Products Frequently Ask Questions

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.


An 18% gray background reduces distractions and color bias, helping in a more accurate assessment.


We provide professional training to customers along with user manuals for the proper operation and maintenance of haze meters. If you have any problems during use, you can contact our experts who will quickly help you solve the problem


Record the L*a*b values of the sample and the reference with a calibrated spectrophotometer or colorimeter. Compute the difference in the color by use of ΔE. The lower the Delta E, the more accurate the result. The difference in energy, ΔE < 1, is generally assumed to be invisible to the eye.


Our machine is packed by standard export wooden box, it won’t be damaged. We’ve delivered many testing machines abroad by sea or by air without damage.

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.


An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.

A haze meter measures the light.  It quantifies the measure of transmitted light across a material and the degree of scattered and diffused light.


Now our testing machines have been sold to more than 80 countries, like USA, Canada, Russia,UK, Italy, Germany, European , India, Pakistan, Philippine, Singapore, Malaysia,Thailand , Vietnam, Korea,Saudi Arabia,Brazil...and so on. We sell to the global market.

Haze Meters are utilized in production and quality assurance in the plastics, glass, films, and coatings industries, where transparency and example are essential.
