Overview
The JKCH-1250 dual-use thickness gauge is a nondestructive testing instrument using magnetic and eddy current thickness measurement methods. It can be used to measure the nonmagnetic film thickness on magnetic metal substrates (such as steel, iron, alloys, etc.) and the nonconductive film thickness on nonmagnetic metal substrates (such as copper, aluminum, zinc, etc.).
Features
1. Adopt the principle of magnetic Induction and eddy Current dual-use thickness measurement.
2. Small measurement error, high reliability and good stability.
3. Easy to operate.
4. Light weight, only 82g (without battery), good portability.
Principle
The instrument works based on the principle of magnetic Induction and eddy Current. When measuring nonmagnetic coatings on magnetic substrates, the principle of magnetic Induction is used; when measuring nonconductive coatings on nonmagnetic metal substrates, the principle of eddy Current is used to realize nondestructive Film thickness measurement.
Applications
Manufacturing, metal processing, chemical industry, commodity inspection
Steps
1. Select the correct measurement mode according to the material of the tested substrate (magnetic or nonmagnetic).
2. Ensure that the measurement area meets the minimum curvature radius and minimum substrate Film thickness required by the instrument.
3. Place the Probe vertically on the surface of the coating to be tested.
4. Read the Film thickness value on the display screen.
Notice
• Make sure that the Probe is perpendicular to the coating surface during measurement.
• The measurement area must meet the minimum curvature radius requirements (convex radius 5mm, concave radius 25mm).
Film thickness requirements (0.2mm) must be met.
• The diameter of the measurement surface should not be less than φ 15mm.
If you don't use the instrument for a long time, remove the battery.
