Low pressure pressure gauge has sensitive element for measuring small pressures. It is generally used to measure the micro-pressure and negative pressure of gas.

Diaphragm pressure gauge is a pressure measurement instrument that separates the measured medium and the sensitive element with an isolation diaphragm. Diaphragm seal type pressure gauge is suitable for measuring the medium pressure of strong corrosion, high temperature, high viscosity, easy to crystallize, easy to solidify, and solid floats. Diaphragm seal material can be stainless steel 316, Hastelloy C276,titanium or Tantalum materials, it can be used to measure such as wet chlorine, hydrochloric acid (HCL), NaClO sodium hypochlorite.,etc.

Low pressure pressure gauge can be used in chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering and plant construction.
