Look for dirty or fingerprinted glass along the optical path, recalibrate with standards, and check the set-up for outside light so that it is controlled. If the problems still exist, please reach out to the helpdesk or book a service with your professional service.

The best tool for measuring clear coat thickness is an ultrasonic coating thickness gauge. It is capable of measuring the thickness of each layer of paint on the vehicle, even the clear coat. This is common in automotive refinishing and inspection.

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.

The Colour Assessment Cabinet (CAC) is a controlled environment used for the visual evaluation of color wherein the light sources are consistent.

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

A coating thickness gauge measures film layers by identifying shifts in magnetic flux, eddy currents, or ultrasonic echoes as they penetrate the coating. The gauge calculates thickness based on the magnitude of these signals. This universally accepted approach results in quick, reliable, and non-invasive measurements. 

Color measurement methods involve visual approximation (against color charts), colorimetry (by means of filters and detectors), spectrophotometry (a more detailed spectral analysis), and image analysis by computer. These are color measurement methods that are applied in the laboratory, production, and quality assessment.

Plastics, glasses, films, coatings, and packaging materials are common uses of hazemeter to monitor consistency and quality. 

Ambient light, heat, and moisture levels should be regulated. The use of colored walls and reflective surfaces should be avoided, as they can damage the assessment of the sample colors visually.

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.
