Material characteristics - Portable air pressure gauge with black steel housing and frame, plastic window, built-in brass connection assembly; Center rear mounting design
Application - 1/4 air pressure gauge is suitable for NPT 1/4" thread barometer, widely used in various pneumatic equipment, such as air compressors, pneumatic tools, etc
Applicable medium - The low air pressure gauge can test the pressure of air, water, oil and gas, suitable for a variety of industrial and domestic use scenarios
Note:
1. The instrument should be properly maintained and should not be shaken violently during use or handling to avoid damage to the instrument.
2. The working pressure range of the instrument should not be more than 70% of the upper limit of measurement.
3. The working pressure of the meter should not be more than 50% of the upper limit of the measurement when it is used to work on the violently vibrating object.
4. When calibrating the gauge with the precision gauge, the absolute error of the precision gauge should be less than one third of the maximum allowable error of the inspected table before it can be used.
5. In order to ensure the accuracy of instruments, regular inspection and verification should be carried out. 维
