Hongqi Instrument, established in 1993, is one of the leading manufacturers and suppliers of 150mm lower/back mount high precision pressure gauge m20*1.5,g1/2'',1/2'' npt ±0.25/0.4% accuracy in China.

In the circumstances of strong corrosive atmosphere, more dust and easy spraying liquid, the suitable shell material and protection grade should be selected according to the environmental conditions.

The selection of measuring range for pressure measuring instruments should meet the following requirements: 1) when measuring stable pressure, the maximum working pressure should not exceed 2/3 of the upper limit of measurement. 2) when measuring the pulsating medium pressure (such as pump, compressor and fan outlet pressure), the normal operating pressure should be 1/3 to 1/2 in instrument range.12.png
