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

Techniques of measuring color are visual color comparison, colorimetry (with colorimeters) and spectrophotometry (measuring spectral reflectance), and image analysis. Both techniques measure the reflection or absorption of light by materials and are commonly quantified. Therefore standardized in color spaces such as CIELAB or RGB.

Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.


Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

Gloss level is not given out in percentage but in gloss units (GU). In practice, however, 100 GU is considered 100 percent reflective. To contrast visually, the 20-40 GU is a low-gloss surface, and 85 or more is almost 100 percent mirror-like reflection.


Always a pre-production sample before mass production; Always final Inspection before shipment; 

Take L*a*b* readings of two samples using a colorimeter or spectrophotometer and calculate color difference using the 3 formula (Delta E). The difference in 0 is the reported Delta-E, which shows how visible the change is, whereas the thresholds define the acceptability as per the application requirements.


Spectrophotometers can only measure haze if it has haze measuring capabilities, as many measure color and transmittance.


Gloss is the general reflectivity of a surface, which encompasses a variety of degrees. One particular type of finish is high gloss, which has the maximum shine and reflectance. It increases the richness but emphasizes flaws as compared to satin or matte.

The gloss scale is normally measured against the scale of 0 to 100 gloss units (GU). The scale is zero at matte and 100 at a mirror. Other very smooth surfaces can be over 100 GU at lower angles, such as 20°.
