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.

Nominal diameter	50 mm
Accuracy	±1.5 % of full scale (Only available with 0.6 and 1 MPa) ±2.0 % of full scale
Scale range (MPa, kPa, bar)	0 ~ 0.1 MPa to 0 ~ 1 MPa
Working pressure	Steady pressure : 75 % of full scale
Working temperature limits	Ambient : 10 ~ 30 °C
Temperature effect	Accuracy at temperature above and below the reference temperature (20 ℃) will be effected by approximately ±0.8 % per 10 ℃ of full scale
