Overview
LEEB Coating thickness gauge leeb261 is a High Accuracy Coating thickness gauge that can quickly, non-destructive and precise measurement of coatings and platings. It can be used in both laboratories and engineering sites. By applying different probes, it can also meet a variety of measurement needs.
Features
1. Full Chinese menu interface operation, simple and convenient
2. Adopt eddy current thickness measurement method for nondestructive measurement of rubber, plastic, paints, oxide films, etc. on nonmagnetic metal substrates
3. There are two measurement methods: continuous measurement method and single measurement method
4. It has two working modes: direct mode and group mode
5. There are five statistics: Average, MAX Maximum, MIN Minimum, Number of Tests, Standard Deviation
6. A variety of calibrating methods: the instrument is basically calibrated to zero, and the system error of the instrument can be corrected by calibrating five test pieces
7. With storage function: can store 4 types of workpieces, each type of workpiece 26 groups, each group of 15 measurement values, a total of 1560 measurement values
8. With deletion function: delete a single suspicious data appearing in the measurement, and delete all data in the storage area
9. Set the limit: the measurement value outside the limit can automatically alarm
10. There is a beep prompt during the operation
11. Highlight LED backlight display, easy to use in gray environments with rays of light
12. There are two shutdown modes: manual shutdown mode and automatic shutdown mode
Principle
This instrument adopts eddy current thickness measurement method, and conducts coating thickness measurement through eddy Current principle.
