Description
Refrigeration Pressure Gauge
Applications
Refrigeration Pressure Gauge is used to display pressure and temperature when measuring Freon R404a R507 R134a R22 refrigeration systems. Suitable for all liquid media that will not attack copper alloy parts.
This kind of gauge, also known as Freon manometer, is used to measure pressure in freezing and air conditioning in cold rooms, industrial refrigerators, cold filling equipment coal as well as central air conditioning.
The refrigeration pressure gauge has the same general structure but with stricter specific characteristics, using a special welding gauge and are tested in order to prevent leakage of coolant.
The Freon manometer is used refrigerants such as R22, R507, R404a, R134a,
