Rough Substrate Calibration using the Elcometer 456 Coating Thickness Gauge
This video will help you get the best performance from the Elcometer 456 Coating Thickness Gauge and make the best use of the gauge’s ±1% accuracy by calibrating the coating thickness instrument to suit the application.
Rough, or 2 Point Calibration, is the ideal method for calibrating the dry film thickness gauge on rough or blasted profiled metal substrates, or for substrates where there are significant differences in the magnetic or electrical properties of the substrate.
Formal quality systems, such as those described in ISO 9001, require coating thickness gauges to be properly controlled, logged and calibrated. Increasingly, users are specifying that the readings taken by thickness gauges are traceable to National Standards.
