Accurate readings can be obtained by keeping the sample clean, regular calibration, control of ambient light and appropriate measurement settings.

Colorimeters or spectrophotometers are used to measure liquid color. They measure light coming through or reflecting off the liquid. Readings can be reported as Lab*, RGB, or absorbance units. So that objective color analysis can be used to control quality, or to measure chemical concentration.

Consistency in calibration is important to account for imbalances arising from wear and tear of the probe, probe pressure, variation from the environment, and fluctuations in daily usage. This is also necessary to maintain the best quality to various international standards.

A colorimeter is used to measure absorbance at selected wavelengths with the help of filters, which is suitable for rapid comparison of colors. A more advanced spectrophotometer has a monochromator. It can measure a larger range of the spectrum of light and is more accurate. You can also get detailed color data at visible and non-visible wavelengths.

Set the 3nh booth in a tidy, stable position with neutral, clean surroundings, adequate airflow, and a reliable power source, and position it away from direct sunlight or mirrors. 

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

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. 

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

When using a Pantone light box, each sample should be positioned flat and nearby the other samples, but not overlapping. Each one should also be in the middle of the light box, and the surfaces of the light box should be clean and non-reflective.
