About Us

3nh specializes in high-precision color measurement instruments, including colorimeters, spectrophotometers, and haze meters, serving industries like textiles, plastics, and coatings. With innovative R&D and global reach, we deliver reliable solutions for color management and quality control, trusted by customers in over 80 countries.

Multi-angle spectrophotometer

The Ultimate Tool for Precise Angle-Dependent Color Measurement

Are you struggling to capture consistent color data for metallic, pearlescent, or effect finishes? Do standard fixed-angle spectrophotometers fail to match real-world viewing scenarios in your production line? The 3nh Multi-Angle Spectrophotometer solves these challenges—becoming the go-to color measurement solution for industries where color accuracy defines success.


Why 3nh Multi-Angle Spectrophotometer Stands Out for Your Color Testing Needs

Unlike basic spectrophotometers that only measure color at a single fixed angle, 3nh’s advanced multi-angle design simulates how humans actually perceive color in daily life. This makes it indispensable for materials with angle-dependent color effects (e.g., metallic car paints, pearlescent cosmetics, or iridescent plastic films).

1. Unmatched Accuracy for Angle-Sensitive Colors

2. Tailored for High-Demand Industries

Our multi-angle spectrophotometer is engineered to meet the unique needs of sectors where color matters most. Search terms like “multi-angle spectrophotometer for automotive” or “cosmetic color measurement tool” lead customers straight to 3nh because we deliver industry-specific value:

3. User-Friendly Design for Seamless Workflows

Even with advanced technology, 3nh prioritizes ease of use—so your team can focus on results, not complicated setup:


Intuitive Software

Built-in tools for color difference calculation (ΔE), data analysis, and custom reporting. Export results in Excel/PDF formats for quick sharing with suppliers or internal teams.


Portable & Durable Options

Choose from benchtop or handheld models (depending on your needs) for flexibility—whether testing in a lab or on the production floor.


Global Support

3nh offers technical support and calibration services worldwide, ensuring your spectrophotometer stays accurate and reliable long-term.

Multi-angle spectrophotometer Frequently Ask Questions

Pick a haze meter that correlates with your materials, precision needs, and applicable testing protocols. For lab-level precision, a bench-top version is advisable; for a rapid field check, a portable haze meter is appropriate. International standards must be met at all times.


The ΔE (Delta E) formula of the CIELAB color space is usually used to measure color difference. The difference is measured in a colorimeter or spectrophotometer to gauge the level of perceptibility of the difference between two samples in terms of L*a*b*.


Color evaluation will change based on how a sample is viewed.  A 45° viewing angle to the source is recommended to reduce shading and achieve consistent comparison.

Now our testing machines have been sold to more than 80 countries, like USA, Canada, Russia,UK, Italy, Germany, European , India, Pakistan, Philippine, Singapore, Malaysia,Thailand , Vietnam, Korea,Saudi Arabia,Brazil...and so on. We sell to the global market.

With over 1 million measuring instruments sold, our expertise is our greatest asset, enabling us to work with our customers on solutions to complex measurement challenges.

The number of reflected light is a measure assigned by a gloss meter as a gloss unit (GU). It is a normalized quantity in which 100 GU is normally a perfect reflection at 60°, and 0° GU is a full diffusion.


Yes, we can offer quality certification issued by our lab free of charge, or issued by third-party international inspection Organizations with extra charge, please contact us for confirmation.

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses


A powder coated surface is most commonly measured for thickness post curing using a digital coating thickness gauge. This method is non-destructive, helps verify coverage uniformity and meets quality control standards. A powder comb gauge is used to estimate thickness for a pre-cured coating.

Samples should be cleaned, dried, and scratched-free to obtain consistent haze measurements.


Of course. Light booths can determine the color of plastic materials, paints, and coatings used in cosmetics, leather, and even pottery. Light booths used to assess and determine precise color comparison can be used on a variety of materials.
