Principle
The instrument works based on the principle of magnetic thickness measurement and eddy current thickness measurement. The magnetic thickness measurement method is used to measure the thickness of nonmagnetic coatings (such as paints and plastics) on magnetic metal substrates (such as steel and iron), and to determine the coating thickness by detecting the change of Magnetic flux. The eddy current thickness measurement method is used to measure the thickness of nonconductive insulating coatings (such as enamel and rubber) on nonmagnetic metal substrates (such as copper and aluminum). The high-frequency electromagnetic field generated by Probe is used to form an eddy current in the conductor, and the coating thickness is obtained by measuring the change of eddy current.
Applications
Manufacturing, metal processing, chemical industry, commodity inspection
Steps
1. Select the appropriate Measurement mode according to the material of the tested substrate (magnetic or nonmagnetic).
2. Zero-point calibrating in the coating-free area of the substrate that requires measurement, or Automatic calibration using standard sheets.
3. Place the instrument Probe vertically and smoothly on the coating surface to be tested.
4. Read the measurement thickness value displayed on the display screen.
5. Use the statistics function to view the MAX Maximum, MIN Minimum or Average of multiple measurements.
Notice
• Measurement mode (magnetic or eddy current) should be correctly selected according to the type of substrate before measurement.
When calibrating, ensure that the surface of the substrate used for calibrating is clean, flat, and free of coatings.
• Probe should remain perpendicular to the coating surface during measurement and ensure smooth contact.
• The measured area must meet the minimum measurement surface requirements (25 × 25mm).
• When measuring the curved surface, pay attention to the minimum curvature radius limit (convex 5mm, concave 30mm).
• The thickness of the substrate needs to meet the thinnest requirements (magnetic substrate ≥ 0.2mm, nonmagnetic substrate ≥ 0.05mm).
• Please use it at the Ambient Temperature (0~ 50 ℃) specified by the instrument.
When a low power display appears on the screen, the battery should be replaced in time (1.5V * AA).
When the instrument is not in use, it should be stored at the specified storage temperature (-10~ 60 ° C).
