A high temperature Thickness Gauge is an instrument used to measure the surface thickness of an object in a high temperature environment. The following are the selection points and precautions:

Measuring range: When choosing a high temperature Thickness Gauge, it should be considered whether its measuring range is suitable for the required measuring task. Generally speaking, the measurement range of the instrument should be between 0-5000um.
Measuring temperature range: The high temperature Thickness Gauge needs to be used in a high temperature environment. Therefore, when selecting, it should be considered whether its measuring temperature range can meet the requirements of the required measuring task.
Accuracy: Accuracy is an important indicator that affects the accuracy of measurement results. Therefore, when choosing a high-temperature Thickness Gauge, you should choose an instrument with high precision.
Display method: The display method of the high-temperature Thickness Gauge should be convenient and quick, and the digital display method is more common. Some advanced instruments also have LCD screen and backlight function.
Data storage: Some advanced high temperature Thickness Gauges can store multiple sets of data and can transfer data to a computer or mobile device via USB or Bluetooth.
Operation method: When choosing a high-temperature Thickness Gauge, you should consider whether its operation method is simple and easy to understand, and whether it needs special training to master it.
Probe material: The probe of the high temperature Thickness Gauge needs to be made of high temperature resistant material to withstand the measurement requirements in high temperature environment.

Calibration: Before using a high temperature Thickness Gauge, calibration is required. 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 high temperature Thickness Gauge may be affected by environmental factors, such as temperature, humidity, etc. 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 high-temperature Thickness Gauge, and timely cleaning and replacement of accessories such as probes will ensure its long-term use effect.
