Measuring principle 
This instrument has a unique single external probe which uses the principle of electromagnetic induction to measure the thickness of non-magnetic coatings on magnetic substrates and eddy current principle to measure thickness of non-conductive coatings on non-magnetic substrates.
Applications
The instrument is designed for non-destructively measuring the thickness of coatings on ferrous and non-ferrous substrates. It can be used to measure thickness of paint, galvanizing layer, lacquer layer, porcelain enamel, phosphide layer, copper tile, anodizing layer, varnish, plastic coatings, powder, etc.
Features
- Unique single probe for F and NF substrates with automatic substrate recognition.
- Zero-point calibration and multi-point calibration.
- Data storage and recall.
- Statistics of max, min and avg value of readings calculated and displayed.
- Backlit LCD display.
- Metric/imperial conversion.
- Single and continuous measuring modes.
