The instrument supports LED, HMI, fluorescent, flash, and natural-light sources. Firmware enhancements add expanded interpretation through TM-30, TLCI/TLMF, SSI, and CRI comparisons, along with single and continuous measurement modes. This is particularly useful for photographers, filmmakers, and lighting professionals who need to compare fixtures or evaluate how a source renders color. Illuminance readings in lux, foot-candle, lux-second, and foot-candle-second add another layer of practical utility.
Its main limitation is workflow focus. This is a light meter and spectrum analyzer, not a reflective spectrophotometer for comparing paint, ink, or physical samples. Users needing CMYK density values, sample color libraries, or print-control-strip targeting should choose a specialized surface-color model. Even so, the C-7000's portable form and broad range of lighting metrics make it a flexible instrument for field work and visual-production decisions.
Choose the C-7000 if your main goal is to evaluate illumination across several fixture types or inspect the color-rendering behavior of a lamp. It is particularly appealing for users who want more spectral detail than a basic light meter without moving into print-production hardware. For those needs, it is the most versatile general lighting recommendation in this guide.
Color-Rendering Insight for Creators
The added TM-30, TLCI/TLMF, SSI, and CRI comparisons make the C-7000 useful when evaluating the appearance and color behavior of different fixtures. That information can help creators choose lighting that better supports skin tones, product presentation, and scene consistency.
Illumination and Exposure in One Tool
Lux and foot-candle measurements bring practical exposure context to the spectral data. The C-7000 therefore helps users evaluate both the intensity and qualitative character of a light source without moving to a separate illuminance meter.

Its library of more than 200,000 paint colors includes brands such as Benjamin Moore, Behr, PPG, Valspar, and Sherwin-Williams. Users can also build a cloud-integrated color library, which adds value for teams that want a more structured color workflow than isolated measurements can provide.
Some advanced capabilities are not included outright. Nix Print Pro is a separate purchase, and enhanced Pantone, RAL, and NCS compatibility is offered through subscription access. Buyers whose work depends on one of those libraries should include the ongoing software cost and platform requirements in their decision. The standard package, however, already covers many common color measurement tasks.
Choose the standard Nix Spectro 2 for general color work across multiple material types, especially when portability and app-based library access are priorities. It is a strong choice for print specialists, paint users, and quality-control teams that want more data than a basic color meter. The 2mm version listed separately is better for tightly controlled print targeting, while this model offers the broader workflow.

Customization functions and storage for up to 99 measurements make it practical for repeated set checks and comparisons.
The C-800 is centered on light-source analysis rather than material color. It does not offer the print-density, aperture, or sample-library features found in surface spectrophotometers, so it would not be the primary choice for press control or paint matching. Its cost category also places it above general-purpose handheld tools, which is justified for users who value the refined display, broad measurement range, and dedicated production controls.
Choose the C-800 when accurate film and photography lighting decisions are central to your work and you want more detailed spectral information than a conventional light meter provides. It is especially useful for set technicians, cinematographers, photographers, and lighting designers who repeatedly compare fixtures. For those users, it is the premium lighting-focused choice.
Faster Set-Side Comparisons
The swiveling head and touchscreen reduce the need to reposition the user's body awkwardly when checking fixtures from different directions. Customizable settings and 99-record storage also support busy shooting days with repeated measurements.

We may earn a commission when you buy through this link, at no additional cost to you.
A large five-inch touchscreen presents real-time data and gives users direct access to measurement parameters. Integration times from 50 microseconds to 10 seconds provide control for different signal conditions, while auto-zeroing helps simplify field setup. The included PC software supports data transfer, spectral graph analysis, and more detailed review of captured readings.
The absence of a customer rating means the documented specifications carry more weight in the assessment. It also does not advertise the same integrated workflows for CMYK density, paint matching, or photographic color-rendering metrics. Its 430 g weight and portable form help offset the fact that it is built around technical analysis rather than a simple color-reading task.
Choose this model for LED engineering, spectral research, wavelength tuning, or any workflow that needs near-infrared coverage. It is best suited to users who want to inspect and export spectral curves rather than simply match a visible color. For laboratory and product-development applications, that distinction makes it a more specialized and potentially more useful instrument.
Visible and Near-Infrared Coverage
The 1050 nm upper limit allows analysis beyond ordinary visible light. This is valuable for LED development, environmental measurements, and research applications where near-infrared behavior is important.
Software for Spectral Review
Real-time visualization on the touchscreen is complemented by PC-based transfer and graph analysis. Users can retain more detailed spectral information instead of relying only on a single summarized metric.

This dedicated design improves repeatability in workflows where an operator might otherwise struggle to hold a handheld instrument over a tiny target. The product is suggested for use with Nix Print Pro, which is sold separately and is intended to surface actionable production insights. That workflow can help reduce waste and minimize downtime by turning measurements into process decisions.
The targeting requirement is also its main constraint. The manufacturer recommends it only for color professionals in the print industry, and it will not function without the jig. Users outside print production may find that restriction unnecessarily limiting, while print specialists may see it as essential for consistent placement. Pantone, RAL, and NCS compatibility is available through subscription rather than as a standard included library.
Choose the 2mm model when consistent measurements on print control strips are the priority and the team already works with compatible print software. It is less attractive as a general color meter but well matched to press-side and packaging quality-control tasks. For professionals in those fields, the targeting jig justifies the specialized format.
Repeatable Small-Area Sampling
The 2mm jig gives operators a physical reference for placing the instrument consistently. That is valuable for control strips, spot-color targets, and other compact print areas where hand placement alone can introduce variation.
Production-Oriented Print Software
Nix Print Pro compatibility adds context to the raw measurement by supporting a wider print-quality workflow. Because it is a separate purchase, teams should verify that the software fits their existing press processes and reporting needs.

We may earn a commission when you buy through this link, at no additional cost to you.
Purple light uses a peak wavelength of 395 nm, blue light uses 430 nm, and visible light spans 380–760 nm. The meter provides 0.1% resolution and stated accuracy of ±2% for colorless and transparent material. Self-calibration and auto-calibration reduce the need for manual adjustment, while simultaneous PL, BL, and VL readings simplify comparison.
This focused design means it cannot replace a full spectral analyzer for lighting evaluation or a surface spectrophotometer for paint and print. Its value lies in delivering transmission results that may not be practical to infer from a general instrument. Buyers should also consider that no customer rating is available in the supplied data, so the documented performance claims deserve careful review against their own standards.
Choose this meter for eyewear, lens, optical-material, or anti-blue-light testing where transmission is the central concern. It is especially convenient for repeat inspections because the sample can simply be placed in the test position and multiple results appear together. For general laboratory analysis, choose a broader spectral or color instrument instead.
Fast Material Comparison
Simultaneous PL, BL, and VL readings make it easier to compare transparent samples during product development or quality checks. The straightforward placement workflow also reduces setup time for recurring inspections.
Built-In Calibration Simplification

Buying Guide – How to Choose the Best Spectrometer 2
Choosing a spectrometer 2 starts with the material or light source you need to measure. Spectral range, optical geometry, repeatability, software, and operating environment determine whether a model will fit your workflow.
Define the Measurement Task
A lighting analyzer, reflective spectrophotometer, print densitometer, and transmission meter may look similar while answering entirely different questions. Photography and cinematography users need CCT, CRI, SDCM, spectral curves, and illuminance. Print teams need density, dot area, overprint, contrast, and target positioning. Paint and coating users need reflectance, Delta-E, and access to color libraries. Eyewear and lens testing centers need transmission rather than reflected-color data. Selecting the task first prevents a technically capable device from becoming an expensive mismatch.
Check the Spectral Range
Visible-light instruments commonly operate from approximately 380 to 780 nm, which is appropriate for most photography, architectural lighting, and color inspection. Devices extending to 1050 nm can also examine near-infrared behavior, making them more relevant to LED engineering and laboratory analysis. Transmission meters may divide the visible range into specialized purple, blue, and broader visible categories. The correct range is the one that includes every wavelength your application and compliance target requires, not simply the largest advertised figure.
Understand Optical Geometry
Measurement geometry controls how light reaches the sample and sensor. A handheld analyzer designed for light sources may have no relationship to a D/8 reflective spectrophotometer used on painted or printed surfaces. Aperture size also matters: a large opening is easier to position over broad areas, while a small opening can isolate fine details. Print-focused versions may use a targeting jig to place the instrument accurately. Verify the geometry, aperture dimensions, and any mandatory positioning accessories before choosing.
Prioritize Repeatability
Repeatability describes how closely repeated readings agree under the same conditions. It is especially important in print, coating, paint, and manufacturing quality control, where a small variation can trigger a reject or process adjustment. Published dE*ab figures can help compare devices, but they should be interpreted with the test method, material, and operating conditions in mind. A visually appealing graph is less valuable than stable readings that a quality team can use as a consistent reference.
Review Software and Data Export
Standalone readings are useful for immediate decisions, but recurring workflows often require stored data, reports, charts, comparison libraries, or integration with existing color-management systems. The Nix models use the Nix Toolkit app and offer optional print or standards-library services. Other instruments rely on PC software, while some support mobile applications. Check operating-system compatibility, data-transfer method, cloud requirements, subscription terms, and whether export formats fit your records before purchasing.
Assess Required Color Metrics
Color temperature, CRI, R9, TM-30, TLCI, SDCM, Delta-E, CMYK values, and spectral curves each reveal something different. Photography users may prioritize rendering indices and visible spectra, while print operators need density and process indicators. Paint users often need search-and-match libraries, while coating specialists may focus on CIE-Lab, LCh, and reflectance. Make a short list of the outputs required for every stage of your process and ensure the candidate supports each one without relying on an unrelated feature.
Consider Portability and Environment
A handheld format is useful for inspecting fixtures, samples, lenses, or production areas away from a bench. Screen size, controls, battery use, protection from water or oil, and operating-temperature limits influence field practicality. A larger display may be easier to read, while a smaller body may be more convenient for repetitive inspections. Rugged construction matters in factories and outdoor sites but may matter less in a controlled studio or laboratory. Select for the environment where the instrument will actually operate most often.
Evaluate Workflow Accessories
Mandatory targeting jigs, calibration bases, reference standards, cables, and application software can be central to accurate operation. The Nix Spectro 2 2mm will not function without its targeting jig, and the D/8 model uses a calibration base and zirconium reference for stability. Some tools also depend on separately purchased print software. Review the full accessory list, expected calibration interval, and physical consumables before treating the instrument as a complete solution.
How to Use and Care for Your Spectrometer 2
Begin by reading the instrument's operating instructions and identifying the correct measurement mode for your material. Clean the sensor window and remove dust, fingerprints, or residue with the approved method. For a light-source analyzer, position the sensor perpendicular to the source at a consistent distance. For surface measurement, place the sample beneath the designated aperture and use the viewing guide or targeting jig. Avoid squeezing the instrument against fragile or curved samples.
Allow the device to stabilize after switching on, then perform the recommended calibration or zero procedure. A dark reading may be required for some lighting meters, while reflective units may need a white reference and a spectrophotometer may need its calibration base. Take several readings from different representative locations and record them with clear sample identifiers. If a target falls near an edge or transition, reposition it and compare the results rather than relying on one reading.
For ongoing care, store the instrument in its supplied case or a dry protective enclosure away from prolonged direct sunlight, excessive heat, moisture, and impact. Keep the sensor aperture free of scratches and do not clean it with unapproved solvents. Recalibrate when the manufacturer specifies, after a significant temperature change, or whenever readings appear inconsistent. Protect mobile connections, charging contacts, targeting jigs, and reference materials, and back up exported data before updating software or replacing a device.
Frequently Asked Questions
What is a spectrometer 2 used for?
A spectrometer 2 measures the spectral characteristics of light or the way light interacts with a material. Depending on the model, it can report wavelength curves, color temperature, CRI, illuminance, reflectance, Delta-E, CMYK density, or optical transmission. The right choice depends primarily on whether you are examining a light source, a printed or painted surface, or a transparent lens.
Is a spectrometer the same as a color meter?
A color meter usually emphasizes a small set of color values, while a spectrometer examines a broader range of wavelengths. Some modern devices combine both approaches, offering spectral data alongside CCT, CRI, Lux, Lab, or Delta-E readings. Always compare the documented outputs rather than relying on the product category label alone.
Which model is best for photography and film lighting?
The Sekonic C-7000 and C-800 are the strongest lighting-focused options in this guide. The C-7000 is compact and includes illuminance plus several interpretation metrics, while the C-800 offers a larger swivel touchscreen, a broad spectral range, and extensive color-temperature coverage. The HP320 is also relevant for simpler visible-light checks and photography illuminance work.
What should I look for in a print spectrophotometer?
Look for CMYK density, dot area, overprint rate, printing contrast, hue error, grayscale, Delta-E, and suitable illuminants such as D50, D55, or D65. Aperture size and positioning accuracy are equally important for small control targets. The Nix Spectro 2 2mm and the multi-aperture digital print spectrophotometer address these needs in different ways.
Do I need a print densitometer for paint colors?
Not necessarily. A reflective spectrophotometer with Lab, LCh, Delta-E, and paint-library functions may be more useful for paint and coatings, while a densitometer is especially relevant to ink density and press-control indicators. The 2mm Nix model is explicitly limited to print professionals, whereas the standard Nix Spectro 2 supports print, packaging, paint, and coatings.
Why does a handheld spectrometer include a targeting jig?
A targeting jig gives the operator a physical way to repeat the same measurement position. Small print targets are easy to cover incorrectly, and even a slight placement shift can change the result. The 2mm Nix Spectro 2 requires this fixture to operate, while other instruments use viewing windows or positioning holes to reduce placement errors.
Can I use one spectrometer for every color task?
No single model is optimized for every task. Lighting meters analyze emitted spectra, reflective spectrophotometers evaluate surfaces, print densitometers add production-specific metrics, and transmission meters assess transparent materials. A broad instrument can cover several related jobs, but specialized instruments usually provide more meaningful results for their intended workflow.
What software should I check before buying?
Confirm the required operating system, mobile or desktop platform, export format, storage system, and cloud behavior. Some products include a full app, while advanced print software, standards libraries, or subscriptions may cost extra. Also check whether calibration records, comparisons, and reports can be integrated into your existing quality-control process.
Final Thoughts on Choosing the Best Spectrometer 2
The Sekonic C-7000 stands out as the most versatile general lighting analyzer in the group, offering spectral interpretation, illuminance readings, and a portable format. The standard Nix Spectro 2 is the stronger choice for surface-color work spanning print, packaging, paint, and coatings, while the Sekonic C-800 delivers the most polished premium instrument for film and photography lighting.
Specialized users should focus on the job rather than on generic spectrometer capabilities. Print teams may need the Nix 2mm targeting setup or a dedicated CMYK densitometer with multiple apertures. Laboratories may value near-infrared coverage, PC spectral analysis, and repeatability. Lens and eyewear testers should choose a meter built specifically for transmission.
Before ordering, verify accessories, software requirements, calibration supplies, supported platforms, and the measurements your process actually needs. Customer ratings and technical details provide useful guidance, but hands-on familiarity with your samples is the final measure of suitability. Prices and bundles can change, so review the current listing and seller information at the time of purchase.
