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

Use our 3nh company approved light. Replace all of the same type together and recalibrate to keep consistent 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

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*.

Samples should be cleaned, dried, and scratched-free to obtain consistent haze measurements.

You can check the shipping status of your order on the website. If you are in urgent need, we can consider making special arrangement for you.

A colorimeter measures the amount of light and the wavelength that is absorbed by a solution. It is a sign that colored compounds are present and the level of their concentration. It is applied in the laboratory and industry to check the concentrations of chemicals, the color of products, and purity.
