The film thickness Tester is an instrument used to measure the thickness of various coatings, paints, electroplating, spraying and other surface materials, and is usually widely used in automobiles, machinery, electronics, construction and other industries. The following are the selection points and precautions of the film thickness Tester.
select points
Measuring range: select the instrument according to the thickness range to be measured. Different film thickness Testers have different measurement ranges, usually ranging from a few microns to a few millimeters.
Accuracy: Accuracy is one of the important performance indicators of the film thickness Tester. Generally, the more accurate film thickness Tester is, the more expensive it is. The balance between actual demand and economic cost should be considered when choosing.
Measurement methods: Film thickness Testers usually have different measurement methods such as magnetic induction, eddy current, and optical. Choose the appropriate measurement method according to the needs. For example, when measuring metal materials, a magnetic induction film thickness Tester is usually used; when measuring non-metallic materials, an optical film thickness Tester can be considered.
Ease of operation: Choose a film thickness Tester that is easy to operate and easy to learn, which can effectively improve work efficiency and reduce error rates.
Data recording and processing: Modern film thickness Testers usually have data recording and processing functions, which can automatically save measurement results, generate reports, etc., which can improve work efficiency and accuracy.
Precautions
Calibration is required before use: The measurement accuracy of the film thickness Tester is related to calibration. Before use, it should be calibrated and operated correctly according to the instructions.
Measure the flatness of the surface: The film thickness Tester has high requirements for the flatness of the measurement surface. If the surface is not smooth, it may lead to inaccurate measurement results.
Avoid magnetic field interference during measurement: The magnetic induction film thickness Tester will be affected by the magnetic field, so magnetic field interference should be avoided during measurement, such as power transformers, motors, induction cookers, etc. may interfere with the measurement results.
Avoid damage to the paint surface during measurement: Avoid damage to the paint surface during measurement, otherwise it may affect the accuracy of the measurement results.
