Film Thickness Gauge is an instrument used to measure the film thickness of various coatings, coatings, thin films, thin plates, etc. It is widely used in industrial manufacturing, material research, quality inspection and other fields. The following are the key points and precautions for the selection of Film Thickness Gauges:
select points
Measuring range: Select the appropriate instrument according to the film thickness range to be measured, usually different probes and measuring ranges can be selected.
Accuracy requirements: Different applications require different accuracy requirements, usually you can choose instruments with different accuracy levels.
Measurement method: Select the appropriate measurement method according to the size and shape of the measured object, including single point measurement, scanning measurement, area measurement, etc.
Probe type: Different probes are suitable for different types of objects to be measured. Select the appropriate probe type according to your needs, such as magnetic induction, eddy current, ultrasonic, etc.
Functional requirements: Select instruments with functions such as automatic calculation, data storage, and data transmission according to needs.
Precautions
Calibration is required before use to ensure measurement accuracy and reliability.
When measuring, it is necessary to keep the probe in parallel and close contact with the measured object to avoid interference with the measurement accuracy due to air or pollutants.
When measuring, it is necessary to pay attention to the relative position of the probe and the measured object to avoid measurement errors caused by position deviation.
During the measurement process, it is necessary to avoid excessive force or wear on the probe, so as not to affect the measurement results.
It is necessary to pay attention to the maintenance and maintenance of the instrument during use, clean and calibrate the instrument regularly, so as to ensure the normal use and long life of the instrument.
