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.

Coating thickness is best measured with a coating thickness gauge specific for the type of substrate. Magnetic and eddy gauges are best for metals while ultrasonic gauges are best for non-metals. These devices provide measurement accuracy and consistency. 

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.

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*.

Each haze test can take from 3 to 10 seconds depending on the device and the type of sample.

Yes, we offer free samples for test, you are welcome to order samples to experience our excellent quality and service.

Color evaluation will change based on how a sample is viewed.  A 45° viewing angle to the source is recommended to reduce shading and achieve consistent comparison.

Our professional team will give you the best suggestion as long as you tell us what kind of test you need to do and the required specification.

 Color is measured using devices such as colorimeters, spectrophotometers, and spectroradiometers. Colorimeters are easier and good for simple color quality tests. Whereas spectrophotometers yield detailed spectral information. Hence, suitable for laboratories and industries.
