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.
