Matters needing attention in coating measurement

Matters needing attention in coating measurement:
1. During the test, it should be noted that the metal magnetism and surface roughness of the standard sheet should be similar to the test piece. 2. During the measurement, the probe is perpendicular to the surface of the measured object. 3. Pay attention to the critical value of the metal on the surface of the measured object when measuring. 4. Pay attention to the curvature of the base when measuring. 5. Remove all magnetic objects around before measuring. If there are objects around, a magnetic plant can be generated. If it will interfere with the magnetic thickness measurement method. 6. Be careful not to measure corners during measurement. 7. Also, keep the pressure constant during measurement, otherwise it will affect the measured reading. 8. Keep the probe of the paint thickness gauge in direct contact with the measured object when performing the test.
