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. 

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