The DR75 has been developed to measure pressure on freon installations. The unit is unique in that the suction as well as the discharge can be read-out on the same pressure gauge simultaneously.

The pressure gauge is built in a stainless steel housing and filled with glycerin, which ensures long lasting reliable operation of the pressure gauge. The seal between the plastic window and the housing prevents leakage by a bayonet catch with a rubber ring.

Surges in pressure that can occur with temperature differences of the glycerine are automatically compensated by a special bellows. A safety blow-out off valve is fitted on top to guard against explosion. A prosper bronze element in an elastic bourdon tube is used, soldered to a large brass junction.

The DR75 is only available in size 100mm. As an option a back flange can be supplied. The pressure gauge can be delivered with several connections, including solder connections.

A R22 temperature scale is standard on the unit and this dial can also be provided with company logos.
