Measuring principle 
This instrument has a unique external probe which uses the principle of eddy current to measure the thickness of non-conductive coatings on non-magnetic metals, specially designed for thin coatings on small workpieces.
Applications
The Instrument is designed for non-destructively measuring the thickness of thin coatings on non-ferrous substrates. It can be used to measure thickness of anodizing layer, varnish, paint, enamel, plastic coatings, powder coatings, etc. It can be used both in engineering fields and laboratories in surface protection and coatings industry.
Features
- Precision measurement of thinner coatings and on smaller workpieces.
- Zero-point calibration and multi-point calibration.
- Single and continuous measuring modes, helpful for curved and tiny objects.
- Metric/ Imperial measuring units (um and mil), auto -power off.
