Coating Thickness Tester, TT270

TT270 coating thickness tester is designed and manufacturedon the basis of current technologies and our years of experience in the field.Hence, it offers many great features as follows:
1. The coatingthickness tester provides two measuring modes: continuousand single.
2. It has two working modes, including direct mode (DITECT)and batch mode (APPL).
3. The thickness tester comes with backlight display, whichenables the user to see the test results clearly even in darkness.
4.Six types of probes are available for various applications, including F400, F1,F1/90, F10, N1, and CN02.
5. The coating thickness tester has low battery indication function andprovides five statistical values: Mean value, Max. value, Min. value, testing numbers.(No.), andstandard deviation (S.DeV).
6. 640 readings can be stored in the memory. The measured values can also beprinted out through an integrated printer.
7. Two measuring calibration modes, manual and auto shutoff modes are available.

Applicationsof TT270 Coating Thickness Tester
The coating thickness tester hastwo measuring methods: magnetic induction (F) and eddy current (N). When it is equipped withF probe, the coating thickness gauge can measure the non-magnetic coatings onmagnetic substrates, e.g., gold, copper, zinc, tin, lead, resin,rubber, glass coatings on the substrates of iron, steel, cobalt and nickel, andmore. When N probe is connected, the instrument canmeasure the non-conductive coating on non-magnetic substrates, e.g., synthetic resin, rubber, glass, paint coatings on the substrates of brass, copper,aluminum, and so on.
