Applications:

Coating thickness gauge is a kind of portable measuring instrument, can take fast, intact, precise measurement of coating thickness. It can not only be used in engineering field, laboratories, but also meet the demand of multiple measuring by using different probes. It is used widely in manufacturing, metal processing industry, chemical industry, commodity inspection field, etc. As an essential instrument in material protection industry.

The F probes measure the thickness of non-magnetic materials on magnetic materials. The N probes measure the thickness of non-conductive coatings on non-magnetic metals.

Features:

* Two measuring methods: magnetic induction (F) and eddy current (N) 

* Two measurement mode: Single and Continuous（Notice：Continuous mode is convenient to measure the coating thickness of curved objects and tiny objects.） 

* Metric/imperial system selectable. 

* Manual or automatic shut down. 

* Automatic memory of calibration value,and automatic recognize the substrate. 

* Operation process have buzzing reminder,while no buzzing in continuous mode.
