Coating thickness meter is a professional instrument used to measure the thickness of coating or coating film. It is widely used in electronics, metals, chemicals, automobiles, aviation and other fields. The following will introduce the selection points and precautions of the coating thickness meter in detail.
select points
Measuring range: When choosing a coating thickness meter, it is necessary to consider whether its measuring range meets the actual needs. Different types of coating Thickness Gauges have different measurement ranges, usually between 0.1-3000μm. Therefore, choose the appropriate model according to the actual needs.
Measurement accuracy and resolution: The accuracy and resolution of the coating thickness meter are important indicators to measure its measurement quality. Generally speaking, the higher the accuracy and the better the resolution, the more accurate and reliable the measurement results will be.
Probe size: Different types of coating Thickness Gauges have different probe sizes, and the appropriate probe size should be selected according to the size and shape of the object to be measured.
Display mode: The display mode of the coating thickness meter is divided into two types: digital display and liquid crystal display. The digital display is more intuitive and can quickly obtain measurement results, while the liquid crystal display can display more information.
Data storage function: The data storage function of the coating thickness meter can record the measurement results and measurement time, which is convenient for later data analysis and comparison. Therefore, if you need to save and process data, you need to consider this function.
Automatic calibration function: Some high-end coating Thickness Gauges have automatic calibration function, which can automatically calibrate the probe and zero point to improve the accuracy of measurement.
Precautions
Before use, the coating thickness meter should be calibrated to ensure the accuracy of the measurement results.
When measuring, pay attention to the flatness and cleanliness of the surface of the measured object, so as not to affect the measurement results.
The probe of the coating thickness meter should be in close contact with the surface of the measured object to ensure the accuracy of the measurement.
During use, it is necessary to avoid external interference such as vibration and impact on the coating thickness meter, so as not to affect the measurement results.
