The key points of film thickness Detector selection
The film thickness Detector is an instrument used to measure the thickness of various coatings, coatings or films. The following are the key points and precautions for the selection of film thickness Detectors:
select points
Measuring range: When choosing a film thickness Detector, it should be considered whether its measuring range can cover the thickness range of the coating, coating or film to be measured. Generally speaking, the measurement range of the instrument should be between 0-5000um.
Accuracy: Accuracy is a very important indicator that affects the accuracy of measurement results. Therefore, when choosing a film thickness Detector, you should choose an instrument with high precision.
Display mode: The display mode of the film thickness Tester should be convenient and fast. The digital display mode is more common, and some advanced instruments also have LCD screen and backlight function.
Data storage: Some advanced film thickness Detectors can store multiple sets of data, and can transmit data to computers or mobile devices via USB or Bluetooth.
Probe type: The type of probe for the film thickness Detector should be selected according to the material and shape to be measured. Generally, there are needle-shaped, plate-shaped, spherical and other probes.
Precautions
Calibration: Calibration is required before using the film thickness Detector. The purpose of calibration is to ensure the accuracy and reliability of the instrument.
Cleaning: Before measuring, the instrument should be cleaned to avoid contamination such as dust or grease from affecting the measurement results.
Measurement location: When measuring, a representative measurement location should be selected to ensure the accuracy of the measurement results.
Environmental factors: The measurement results of the film thickness Detector may be affected by environmental factors, such as temperature and humidity. Therefore, attention should be paid to the stability of the environment during use.
Maintenance: During use, attention should also be paid to the maintenance and maintenance of the film thickness Detector, cleaning and replacing accessories such as probes in time, so as to ensure its long-term use effect.
