Car Paint Film Thickness Tester Digital Coating EC-770 Thickness Probe Tester Description: This compact gauge can be used for non-destructive coating thickness measurement of non-magnetic coatings, e.g. paint, enamel, chrome on steel, and insulating coatings, e.g. paint and anodizing coatings on non-ferrous metals. The internal probe can work on two measuring principles, magnetic induction and the eddy currents. The probe can automatically detect the substrates type (Magnetic or not), and calculate the coating thickness and display it fast. There are five data groups, and readings will be automatically stored to memory for general groups (Not for direct group). Each group has individual statistics, alarm limit settings and calibration. User can recall and delete specified readings easily. User does all operations via standard menu so easily. User can press the CAL button to start calibration freely. Features: 1. 128*128 lattice LCD display, standard menu operations. 2. Two measure modes: single and continuous. 3. Two group modes: direct (DIR) and general (GEN), readings will be lost when power off in direct mode, and not be lost in general mode. 80 readings can be stored for each group. 4. 0 point calibration and multi-point calibration (up to 4 points) for each group. 5. User can recall, delete specified readings, or delete group readings. 6. Statistics display: mean, minimum, maximum and standard deviation . 7. Three probe modes: auto, magnetic and eddy current. 8. User can set high or low alarm limit for each group. 9. Power off automatically. 10. USB interface to data transmission. 11. Low battery and error indication. Specifications: 1.

Power supply: 2*1.5v AAA battery(Not included) 15. Operation temperature: 0℃ to 40℃ (32℉ to 104℉)  16. Storage temperature: -20℃ to 70℃ (-4℉ to 158℉)  17. Size: Approx. 110mm*53mm*24mm (4.33"*2.09"*0.94")  18. Weight: Approx.92g (3.24oz) Application: This instrument can measure the coating thickness without any damage so easily. It can be widely used in testing fields such as manufacturing industry, metal-processing industry, chemical industry, commodity inspection, and it is the indispensable instrument of material surface treatment project. It can stably work in the laboratory, workshop and outdoor.
