80mm Painted Steel Case Refrigeration Ammonia Pressure Gauge 500 psi Cryo Refrigerator Manometer
Description
Usually, a Bourdon tube pressure indicator is mounted vertically. Deviations of +/- 5° relative to the vertical position are permitted. A deviation of more than 5° will have an impact on accuracy.
Applications
Measuring refrigerant ammonia pressure and temperature
Suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system
Process industry: chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering and plant construction
Special features
Excellent load-cycle stability and shock resistance
All stainless steel construction
Ammonia refrigerant scales on dial
