The dial pressure gauges are specially conceived for the measurement of low pressures ranging in mbar, according to EN 837-3 or high pressure in bar. They are suitable to be used on natural gas combustion systems and to measure pressure of noncorrosive fluids at the gaseous state. They are available with 1/4” - 3/8” - 1/2” radial male connection and with 63 - 80 and 100 mm dial diameter size. The standard version is equipped with dual scale in mbar and in H2O mm.
