Precautions for using refrigeration pressure gauge
 Sep 27, 2020|View:1102

⑴ The refrigerant pressure gauge must be vertical: during the installation process, use a wrench to tighten, and the shell must not be twisted; avoid collision during transportation.

When the ambient temperature is -40℃-70℃, refrigerant pressure gauge should be used.

⑶ The working environment vibration frequency is less than 25HZ, and the amplitude is no more than 1mm.

During use, the working environment temperature is too high or the atmospheric pressure of the production and use place

If the indicator value of the refrigerant pressure gauge does not return to zero or the indicator value is out of tolerance, please adjust the zero value before use.

Precautions for using refrigeration pressure gauge

⑸ The use range of refrigerant pressure gauge should be between 1/3~2/3 of the upper limit.

When measuring corrosive gas or high temperature media, please use all stainless steel materials and use safety glass mirrors.

⑺ The refrigerant pressure gauge should be checked frequently (check at least once every three months)

You need to use a refrigerant pressure gauge for measuring corrosive media, and specify the required conditions, such as media material, when ordering.
