Measuring principle

This instrument has an in-built probe which uses the principle of electromagnetic induction to measure the thickness of non-magnetic coatings on magnetic substrates(steel/iron) and eddy current principle to measure thickness of non-conductive coatings on non-magnetic substrates(aluminium, copper, brass).

Applications

The Gauge is designed for non-destructively measuring the thickness of coating and painting. It is essential for material surface treatment and widely used in manufacturing industry, metal-processing industry, chemical industry, commodity inspection area, and able to work steadily in the laboratory, workshop and outdoors.

Features

  • Large Display for better readability.
  • Zero-point calibration and multi-point calibration.
  • Two measure modes: single and continuous.
  • Selectable um/mil measuring units.
