The P870 Series specifically designed for ultra high purity gas distribution system used in semiconductor industry and electronic, medical, biotechnology, pharmaceutical industry.

Service intended
P870 series provide a superior chemical resistant and non-viscous pressure gauge which employs fluorine resin for the wetted parts. It can be used with highly corrosive fluids. The case material is PP resin and resistance to corrosive environments.
