Diaphragm seal pressure gauge is suitable for measuring the pressure or vacuum of corrosive liquid that will not crystallize and solidify.

Diaphragm seal pressure gauges are divided into standard type and all stainless steel type, there are difference in material and measuring range between them. Besides of measuring common pressure, stainless steel diaphragm seal pressure gauge can measure the low pressure of 1.6~40Kpa and vacuum. Stainless steel diaphragm seal pressure gauge with flange connector can be used for measuring the pressure of media, in which granule and deposit exist. So the gauges are widely used for measuring the low pressure of corrosive medium in chemical industry.
