Overview
The SMART SENSOR ST9333 Coating thickness gauge is a precision testing instrument using the dual Measurement principle of magnetic Induction and eddy Current. It can nondestructive measurement of magnetic metal substrates (such as steel, iron) on nonmagnetic Coating thickness, and nonmagnetic metal substrates (such as copper, aluminum) on nonconductive coating thickness, with small measurement error, Reliability, easy operation and other characteristics, is an important tool for quality control in manufacturing, metal processing and other fields.

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) on magnetic metal substrates (such as steel). Coating thickness is calculated by detecting changes in Magnetic flux. The eddy current thickness measurement method is used to measure the thickness of nonconductive insulating coatings (such as paints) on nonmagnetic metal substrates (such as aluminum). Coating thickness is determined by measuring eddy current changes.
Applications
Manufacturing, metal processing, chemical industry, commodity inspection
Steps
1. Measurement mode according to the base material (magnetic or nonmagnetic).
2. Zero calibrate the exposed part of the substrate that needs to be measured, or use the Automatic calibration function of the instrument.
3. Place the Probe vertically and smoothly on the surface of the coating to be tested.
4. Read the measurement results displayed on the screen.
5. The MAX Maximum, MIN Minimum and Average values of multiple measurements can be viewed through the statistical function.
Notice
• Measurement mode (magnetic method or eddy current method) should be selected correctly according to the matrix material before measurement.
• When calibrating, the same exposed base material as the workpiece to be tested should be used.
• Make sure that the Probe is perpendicular to the coating surface and in smooth contact during measurement.
• The measured area must meet the minimum measurement surface requirements (25mm × 25mm).
• When measuring curved workpieces, 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.
• Pay attention to the battery level, please charge it in time when it is low.
