Products Frequently Ask Questions

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


D65, TL84, A light, CWF, and UV are the most common standardized sources used for precise color matching.

A Spectrophotometer color measuring device objectively determines the color of a surface. It is used wherever accurate color matching, reproducibility or deviation control is needed – for example in quality assurance, product development or incoming goods inspection.

Spectrophotometer color measuring devices primarily perform three key tasks:

Capture color information: They detect light reflected, transmitted, or emitted by a sample using optical sensors.
Quantify color data: They convert the captured optical signals into standardized numerical values, such as RGB, CMYK, or CIELAB coordinates.
Compare color consistency: They compare the measured color data of a sample against a target or standard to assess color accuracy and uniformity.


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.

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. 

Light booths and color matching are essential for the textiles, printing, automotive, plastics, cosmetics, and coatings industries. These fields rely on tight color alignment to protect brand value and meet global quality demands for color. 


A colorimeter is a quick and inexpensive method to measure color and to control color in a material or solution. It is used to maintain color consistency during production and to check the chemical concentration. It also assists with the quality control of labs, food, textiles, and pharmaceuticals.


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. 


Inaccurate color rendering, mismatched results, and noncompliance with ISO 3664 or ASTM D1729 can occur when there are deviations.
