Description
Overview
GAOTek wide measurement range coating and material thickness gauge also called coating thickness tester is an instrument that separates the host from the probe. The measuring range is 5000 μm and the meter can automatically identify the measuring substrate. This instrument uses both Hall Effect and eddy current measurement principles to measure the non-magnetic coating thickness on magnetic substrates and the non-conductive coating thickness on non-magnetic substrates. It is a dual-use instrument for both ferrous and non-ferrous substrates.
Features
- No calibration needed, simple zero adjustment for measurement
- Probe supports trigger power-on, auto substrate identification, and switching
- DC-223 tester measures materials up to 5mm thick
- Advanced digital probe technology ensures accuracy and repeatability
