The color measurement theory is the quantification of the interaction of materials with light, either absorption, transmission, or reflection. It employs standard colour spaces (such as CIELAB) and devices (colorimeters, spectrophotometers) to code the visual colour into objective and reproducible data.

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*.

We provide professional training to customers along with user manuals for the proper operation and maintenance of haze meters. If you have any problems during use, you can contact our experts who will quickly help you solve the problem

To keep a neutral background, helping to reduce color distortion and bias.

A haze meter is precise and accurate if the sample is clean, there is a light contamination, and the sample is condition.

Gloss level is the extent of reflectance of light on a surface. It measures the shininess or dullness of a finish, from flat or matte to high gloss. It is important in aesthetic, functional, and quality control applications.

Readings of gloss meters in gloss units (GU) are used to measure shine on the surface. Low GU (0-10) is matte, 10-70 semi-gloss or satin, and above 70 is glossy. Measurement angle is given to the readings: 60° is the normal, 20° is the high gloss, and 85° is the low gloss.

Haze captures the scattering of light, transmittance measures the light that passes through a said material.

Ensure the source, viewing angle, and background are all neutral and standardized, and the samples are clean, and positioned for a side-by-side comparison under each light condition.
