This Thickness Gauge is used to measure the thickness of electroplating or coating on metal surfaces, specifically the thickness of non-magnetic coatings on the surface of magnetic materials such as steel/iron (such as chromium/paint/ceramics, etc.), and the thickness of the coating on the surface of non-magnetic materials such as copper/aluminum (such as paint, etc.). The instrument has a built-in precision probe that automatically detects substrate properties and detects coating thickness through electromagnetic induction and eddy current effects.
This instrument can measure the thickness of coating and plating without damage, quickly and accurately. It is widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields, and is an instrument required for material surface treatment engineering. It can work stably in the laboratory, workshop site and outdoors.


1. Fe indicates that the substrate to be measured is a magnetic material: steel/iron, etc
2. NF indicates that the substrate to be measured is a non-magnetic material: copper/aluminum, etc
3. Automatic shutdown logo, the machine will automatically shut down without operation for 5 minutes
4. Battery level indicator
5. Measurement reading display
6. The SNG indicates that it is currently a single point measurement mode
7. The CON indication is currently in fast continuous measurement mode
8. Numerical units: um is micron, mil is the American customary unit mil
9. Power on and off button
10. UM/MIL key, function 1: unit switching, function 2: press and hold for more than 3 seconds, the machine will be restored to factory settings
11. ZERO button, SNG display (single point mode) is: clear the screen; When the CON is displayed (fast continuous mode), it is: calibration key
12. MODE button, switch mode SNG/CON, SNG display is single point mode, CON display is fast continuous mode
13. Anti-slip groove, convenient for thumb and index finger to pinch the machine during measurement
14. Measure the probe
15. V-groove, which is used to measure convex surfaces, such as the surface of steel pipes
16. Remove the battery cover of the machine and install 4 No. 7 batteries
