What are the requirements of the gas pressure test for the pressure gauge?
The maximum pressure shall not exceed the upper limit of the pressure gauge, preferably at the 2/3 position, and the measurement accuracy is relatively high. If the production needs to be calibrated by the technical measurement Institute, the validity shall be used within the period of validity. The watch list is better. The dial is larger. It looks clearer.
The measuring range of the pressure gauge should be 1.5 times higher than the measuring pressure, and the outer circle diameter of the meter should be 150mm. This is a standard requirement.
