Product Details

70mm 35 bar Brass Connection Blue Cover Refrigeration Pressure Gauge for Manifold

 

Description
Does the temperature shown by the needle always correspond to the temperature of the refrigerant?

Firstly, this is only true if you read the refrigerant temperature on the correct scale. For example, if you measure a pressure in an R22 system, you must read the temperature on the R22 scale, and not on the scales for R12 or R502 (which are other refrigerants).

Secondly, it is, of course, absolutely correct to say that the temperature scales give you the pressure- temperature relationship of the fluid in use. However, don’t forget that this relationship only exist when a change of physical state is taking place.

 

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
