Ammonia pressure vacuum gauge

The ammonia pressure gauge is mainly used to measure the pressure of ammonia liquid, gas or mixtures in the fertilizer production process or in refrigeration equipment. The ammonia pressure gauge can also be used to measure the pressure of ordinary carbon steel and austenitic stainless steel. , alloy structure, and the pressure of various non-corrosive, amorphous and non-solidifying media such as tin-lead alloy brazing materials. Main technical parameters of ammonia pressure gauge Accuracy level: 2.5 (dial 60); 1.5 Operating environment conditions: -40~70℃, relative humidity not greater than 90% Temperature effect: no more than 0.4%/10℃ (the operating temperature deviates from 20±5℃) Selection of pressure gauge for ammonia: model Measuring range(Mpa) Connector thread 60 100 150 -0.1~0;-0.1~0.06;-0.1~0.15;-0.1~0.3 -0.1~0.5;-0.…
