TM-292

TM-292 Coating Thickness Tester

Dual-Mode Smart Detection: Automatically switches between Fe (Magnetic Induction) and NFe (Eddy Current) for versatile applications.
Comprehensive Data Management: 1950 memory capacity with PC software for in-depth statistical analysis.
Real-time Quality Alert: Customizable High/Low limit alarms ensure continuous quality monitoring.

Application

This meter is designed to measure the thickness of non-magnetic coatings on magnetic substrates (Fe) and insulating coatings on non-magnetic substrates (NFe).

It can automatically identify whether the substrate is magnetic or non-magnetic during measurement.
