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-magnetic 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, plating (nickel, copper, chromium, etc.), galvanizing layer, lacquer layer, porcelain enamel, phosphide layer, copper tile, anodizing layer, varnish, plastic coatings, powder, etc.

For coating thickness below 20um, it’s important to zero-calibrate the instrument with uncoated substrate of the sample, and not the provided zero-calibration blocks, for better accuracy.

Features

  • Unique single probe for F and nF with automatic substrate recognition.
  • Zero-point calibration and multi-point calibration.
  • Two measure modes: single and continuous.
