How to calibrate the Elcometer 456 Coating Thickness Gauge in accordance with ISO 19840, for rough surfaces (or blast coated substrates), on ferrous substrates.
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.
The Elcometer 456 Dry Film Thickness Gauge can measure the thickness of a coating on smooth, and on rough or blast coated substrates; and there are a number of calibration methods for each substrate profile.
When measuring on rough surfaces, if you have access to a sample of the uncoated substrate you will be measuring, then you should undertake a rough surface (or 2-point) calibration.
However, if you don’t have access to the uncoated substrate, then you can use the Elcometer 456’s patented Zero Offset calibration method, which helps measure film thicknesses in accordance with ISO 19840.
ISO 19840 simply states that if a blast profile is unknown, you should calibrate on smooth steel and then subtract a predefined correction value from the measurement taken on the coated surface.
The Elcometer 456’s patented zero offset calibration automatically subtracts this correction value from the measurement, so you don’t have to.
The Elcometer 456 is an intelligent gauge, so, once the gauge has been set to the Zero Offset Calibration, it will guide you through the calibration process, one step at a time.
