3nh Multi-angle spectrophotometer is used to measure the color difference for the surface paint which is affected by different viewing angles and viewing conditions. Lightweight, Durable, Accurate—Your On-the-Go Color Expert
The Ultimate Tool for True Color Analysis
The 3nh Multiangle Spectrophotometer features up to 12 measurement angles, with a maximum repeatability of ΔEab < 0.04 and color repeatability of ΔEab < 0.02. It is primarily designed for measuring the sparkle, flop, and granularity effects on object surfaces,It can provide accurate and consistent color measurement for metalllics, pearlescents and other complex special effect finished products.
It can not only measure multi-angle color difference, but also measure and characterize special finishes through multiple measuring angles. Even in the curved surface, it also has high measuring accuracy and stability.
From Car Paint to Cosmetic Pearls: Master Every Shade with Multi-Angle Spectrophotometry
The Future of Special-Effect Color Measurement: Multi-Angle Spectrophotometers Lead the Way
A powerful and portable instrument for color measurement, management, transmission, and report printing.


Adopt 7 illumination sources, 2 receivers to measure 12 measurement angles at the same time

Touch screen can display all Angle measurement results, more intuitive view of the comprehensive data.
High - end Hardware Configuration: Dual - array image sensors; Bluetooth transmission; Concave grating for light dispersion.
Stable Measurement: 400 - 700nm blue - enhanced LED, with the standard deviation controlled within 0.08%.
Color Transfer: Measures the sample's reflection spectrum, providing accurate Lab data, applicable for color matching and color transfer.
Measurement Accuracy: Temperature monitoring and compensation. With a built - in temperature sensor, it monitors and compensates for the test environment to ensure accurate measurement results.
User-Centric Design: Its compact, lightweight design (1.2kg) also makes it ideal for both lab-based testing and on-site inspections (e.g., factory production lines, supplier audits).
Traditional colorimeters often miss subtle color shifts visible at different viewing angles, leading to inconsistent products, costly reworks, and disappointed customers. Our Multi-Angle Spectrophotometer solves this challenge by capturing color data from multiple angles, ensuring your products look perfect, no matter how they’re viewed.

FAQs About Multi-angle spectrophotometer
Color measurement methods involve visual approximation (against color charts), colorimetry (by means of filters and detectors), spectrophotometry (a more detailed spectral analysis), and image analysis by computer. These are color measurement methods that are applied in the laboratory, production, and quality assessment.
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.

Threenh Technology colorimeters provide a color deviation prompt function according to the Lab value, which can provide a reference for color matching. The handheld colorimeter can only indicate blacker, whiter, redder, greener, yellower or bluer, but it cannot provide accurate color formulas. Only with the help of a spectrophotometer and professional color matching software can fully realized automated color matching.
Zero calibration of a hazemeter is a critical pre-measurement procedure to ensure the instrument’s accuracy by resetting its baseline to "zero" when no haze or light attenuation is present.
Align the hazemeter’s measurement window with air or a black background, ensuring no objects block the window.
Press the hazemeter’s zero calibration button and wait for the instrument to complete automatic calibration. At this point, the instrument should display a zero haze value and a zero light transmittance value.
Observe the instrument’s display to confirm the zero calibration result stabilizes near zero. If the zero calibration is inaccurate, repeat the above steps multiple times until the displayed haze and light transmittance values stabilize near zero.
Perform 0-degree calibration before testing, this eliminates inherent instrument drift, environmental interference, or residual signal errors, ensuring subsequent measurements of transparent/translucent samples (e.g., plastic films,pvc, glass, coating, displays and cosmetic packaging) are reliable. Correct for minor instrument deviations caused by long-term use, temperature changes, or power fluctuations.
Calibrating a colorimeter before testing is critical for accurate, reliable color data—counteracting instrument drift, environmental interference, and component wear to ensure measurements reflect true sample colors. It guarantees compliance with industry standards, eliminates costly rework from flawed data, maintains brand consistency across batches/locations, and ensures data comparability with clients or regulators.
Calibrating a colorimeter before use is primarily to ensure the accuracy of measurement data and compensate for errors caused by the aging of internal components (such as light sources and phototubes) or environmental changes.
Below are the specific reasons:
Compensation for Component Aging and Environmental Influences
Compensation for Environmental Factors
Standardization of Measurement Baselines
Operational Specification Requirements
3nh colorimeters are designed for immediate measurement upon startup. However, calibration (via black-white correction) is mandatory for the first use, sudden environmental changes, or abnormal data to restore measurement accuracy.
