CIE 1931 XYZ uses tristimulus values to quantify color, while CIE 1976 L*a*b* is derived from XYZ and is more convenient for describing color direction and comparing perceptual differences. Learn how XYZ, the xy chromaticity diagram, Lab, and spectral measurement data relate.

Metamerism occurs when two samples look similar under one light source but show a visible color difference under another. Learn why it happens, why a low ΔE under one illuminant may not tell the whole story, and how to assess it in product development, color matching, production and acceptance.

Both colorimeters and spectrophotometers can report L*a*b* and ΔE, but they do not obtain color information in exactly the same way. This guide compares tristimulus sensing with spectral measurement and explains why the same sample may produce different readings.

SCI and SCE can produce different L*a*b* and ΔE values for the same sample because they handle specular reflection differently. Learn how gloss affects readings and which measurement conditions customers, suppliers and labs should standardize.

Meat color is a first visual cue for freshness and quality across processing, inspection, cold-chain transport and retail. This guide explains myoglobin, compares visual checks with instrument-based methods, and outlines practical measurement, interpretation and troubleshooting steps using CIE L*a*b*.

From color-changing protective helmets and climbing ropes to anti-counterfeiting packaging, fluorescent mechanochromic materials are finding new uses. A spectrophotometer can quantify color changes under force and help assess the consistency and reliability of these materials in safety applications.

The 3nh TS7700 spectrophotometer measures L*a*b* color values and ΔE on metal enclosures. With SCI/SCE modes, D65 illuminant, a 10° observer and integrating-sphere geometry, it supports consistent color inspection for electronics housings, painted metal and automotive parts.

Water colorimeters measure the color of drinking water, groundwater, mildly contaminated water and other liquid samples. This guide explains calibration, what to check on a calibration certificate, key items under JJF 1689-2018, and TS4010 applications across water, food and beverage, pharmaceuticals, petrochemicals and cosmetics.

Learn how window tint transmission meters measure visible, ultraviolet and infrared light, compare LS160/LS162/LS163/LS182/LS110 models, and choose a meter for different film types. Includes Taiwan’s current VLT requirements effective February 28, 2026.

The YG60L Plus is an in-line, non-contact gloss measurement module with Bluetooth, USB and RS485 connectivity, real-time feedback and a 0.2-second response. Learn how it supports automated, continuous inspection and quality control on production lines.

A color assessment light booth provides a consistent standard-light environment for visual comparison. Learn the uses of D65, D50, TL84, CWF, A and UV sources, and how to choose a booth based on customer requirements, sample size and the actual inspection environment.

Learn when to use 20°, 60° and 85° gloss measurement angles. This guide explains their suitable gloss ranges, a practical selection workflow, industry applications and the benefits of a three-angle gloss meter.

Learn how gloss meters quantify surface reflectance, how 20°, 60° and 85° measurement geometries and international standards work, and how to select, operate and maintain a meter for consistent quality control.

Homogenizers and mixers work differently and suit different processes. Compare their particle-size capability, viscosity range, speed, cleaning, scale and applications to choose the right equipment or combine both.

Compare ASTM D1003, ISO 13468 and ISO 14782 for haze and light-transmittance testing. Learn what each standard measures, how scattering relates to haze, which instruments may fit your sample and what to confirm before acceptance testing.
