This refers to assessing samples with a specific color and maintaining the same alloted time interval on all parameters to ensure neutrality of variables and reproducibility of lightness in the color. 

True color in chemistry is the color seen in a solution or compound in standardized conditions. It depends on electronic transitions in molecules, specifically absorption of a particular wavelength of light, and this depends on the structure of the compound.

The various colors can be measured by the way a surface reflects, absorbs, or transmits light at different wavelengths. These responses may be measured using instruments such as colorimeters or spectrophotometers to give numeric values in a standardized color space such as L *a*b*.

Inaccurate color rendering, mismatched results, and noncompliance with ISO 3664 or ASTM D1729 can occur when there are deviations.

Yes, we can offer Spectrodensitometer 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.

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.

The haze meter test assesses the degree of light scattering that occurs when light traverses a transparent or translucent material, producing a percentage that quantifies example or cloudiness.

Threenh Technology company adheres to independent design, research and development, production and sales of various measuring instruments. 

A spectrophotometer and colorimeter are certain instruments used by scientists to measure color by quantifying reflected or transmitted light. The results are presented in color spaces, such as L*a*b*, RGB, or XYZ. This enables the accuracy of comparison and tracking of the changes in color in chemical or material research.

Follow the calibration steps form 3nh. Don’t touch the sample and drop the measurement light to eliminate external light.
