A service is made up of tub replacement, light source recalibration, internal cleaning, verification of service and color certification retention so that all compliance color standards are retained. 

Opaque liquids and powders can be put into a cuvette for color measurement. 

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.

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

A colorimeter sends light through a solution and measures the amount that is absorbed. It computes the absorbance by comparing the intensity of light before and after passing through. The greater the concentration of the color, the greater is the absorption of the light. It is also possible to quantify the color of the solution.

Smooth and uniform surfaces with a large amount of reflected light directly result in high gloss. Some of the factors are the smoothness of the surface, the type of paint that is being used, the thickness of the coating, and curing. The lesser the surface irregularities, the greater the gloss.

The most important equation is A = 2εcl, where A is the absorbance, 2 is a constant, ε is the molar absorptivity (L/mol cm), c is the concentration (molL-11), and l is the path length (cm). This can be used to relate the absorbance to the concentration, allowing quantification through colorimetric assays.

Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses

Daylight, store light, home light, and UV fluorescence light sources are included in Pantone light boxes as D65, TL84, CWF, A, and UV.
