A calorimeter is used to measure heat that is gained or lost during a chemical or physical reaction. A sample is taken in an insulated container, and a temperature change is measured. This assists in computing the alterations in energy by the equation Q = mcΔT, where Q is heat.

Colorimeters have fixed wavelength filters and LEDs; it is less precise and simpler. Monochromators are applied to spectrophotometers, which scan a spectrum of wavelengths. Giving more detailed spectral information. Spectrophotometers are more sensitive and flexible in complicated analyses.

Always a pre-production sample before mass production; Always final Inspection before shipment; 

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. 

 A gloss meter measures the amount of light reflected from a surface at a specific angle. It's commonly used to assess surface finishes such as paint, coatings, plastics, and paper for consistency, quality control, and visual appearance evaluation.

The principle of colorimetry is the law of Beer-Lambert, which says that the intensity of light absorbed by a colored solution is proportional to the concentration of the absorbing species and the path length. It measures the extent of light that is absorbed at certain wavelengths.

Yes, we can offer 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.

The automotive, aerospace, metal finishing, marine, construction, and manufacturing industries utilize and rely on coating thickness gauges the most. They ensure that coatings are within the expected criteria for functionality, safety, and durability.

In industrial production and quality control, color consistency is one of the core elements determining product quality. Whether it is the metallic paint for automobile coating, the dyeing effect of textile fabrics, or the ink matching in packaging and printing, subtle color deviations may lead to cost waste or damage to brand image.

The LAB color space defines colors with a three-dimensional model:

1. Lightness (L): It indicates the lightness or darkness of a color, ranging from 0 (pure black) to 100 (pure white).

2. Hue and Saturation (a and b):

• The a-axis represents the red-green tendency, with positive values leaning towards red and negative values leaning towards green;

• The b-axis represents the yellow-blue tendency, with positive values leaning towards yellow and negative values leaning towards blue.

It is a globally recognized standard and supported by most modern color measurement equipment. Color is quantitatively analyzed by measuring Lab values with instruments.
