Coating thickness Tester is an instrument used to measure the thickness of various metal and non-metal coatings. Coating thickness Testers are usually used in quality control and surface treatment in the industrial field. Here are some key points and considerations when choosing a coating thickness Tester:
1. Measuring range: When choosing a coating thickness Tester, the instrument should be selected according to the coating thickness range to be measured. Generally, the measurement range of the instrument should be able to meet the application requirements, and at the same time, do not over-purchase a measurement range higher than the requirement, so as to avoid unnecessary cost waste.
2. Measurement accuracy: Accuracy is an important index to measure the performance of the coating thickness Tester. When selecting a coating thickness Tester, an instrument with sufficient precision should be selected to ensure the reliability and accuracy of the measurement results.
3. Measuring principle: The measuring principle of coating thickness Tester is usually divided into many kinds, such as magnetic induction, eddy current, optics and so on. When selecting an instrument, the appropriate measurement principle should be selected according to the application requirements.
4. Coating type: Different types of coatings have different requirements for the selection of measurement principles and instruments. For example, magnetic induction techniques are suitable for the measurement of metallic coatings, while optical techniques are suitable for the measurement of non-metallic coatings.
5. Use environment: The coating thickness Tester is usually used in different environments, such as in the laboratory, workshop, field or outdoors. Therefore, when choosing a coating thickness Tester, the use environment should be considered to choose a suitable model.
Precautions
1. When using the coating thickness Tester, follow the instruction manual, and perform calibration and maintenance as required.
2. Before measuring, the measuring surface should be cleaned to ensure the measurement accuracy.
3. When using the coating thickness Tester in different environments, you should pay attention to the influence of temperature and humidity on the measurement, and make corrections.
4. For different types of coating thickness Testers, appropriate calibration standards should be selected, and calibrated and maintained as required.
5. Attention should be paid to factors such as the operating temperature of the instrument, battery life and storage conditions
