Magnetic Coating Thickness Gauge is an instrument for measuring the thickness of coatings, especially for measuring the thickness of magnetic coatings on ferromagnetic materials. The following are the key points and precautions for the selection of magnetic coating Thickness Gauge:
select points
Measuring range: When choosing a magnetic coating Thickness Gauge, the coating thickness range that needs to be measured should be considered. Different types of magnetic coating Thickness Gauges have different measurement ranges, and the selection should be made according to actual needs.
Resolution: Resolution refers to the smallest unit that the instrument can measure the thickness of the coating. The higher the resolution, the more accurate the measurement. Therefore, when choosing a magnetic coating Thickness Gauge, you should choose a model with high resolution as much as possible.
Accuracy: Accuracy is the degree to which a measurement differs from the true value. Typically, magnetic coating Thickness Gauges are accurate to ±3%. For some applications with higher requirements, models with higher accuracy should be selected.
Display mode: There are two display modes of the magnetic coating Thickness Gauge: digital display and pointer display. Digital display has the advantages of accurate and intuitive readings, while pointer display has the advantages of wide display range and low price.
Data storage: Some high-end magnetic coating Thickness Gauges have a data storage function, which can save the measurement data to the instrument for subsequent analysis and processing.
Precautions
The magnetic coating Thickness Gauge should be calibrated before use to ensure that its measurement results are accurate and reliable.
During the measurement process, the magnetic coating Thickness Gauge should be placed at the position to be measured to ensure that the sensor is fully in contact with the surface of the measured object.
When measuring coating thickness, care should be taken to avoid corrosion, abrasion, scratches, etc. in the measurement area, otherwise the accuracy of the measurement results may be affected.
During use, care should be taken to avoid strong magnetic field interference and avoid contact with other magnetic materials.
After use, the magnetic coating Thickness Gauge should be kept in a safe place to avoid damage such as impact and drop.
