Boiler pressure gauge is designed to measure pressure in liquid and gaseous, non-viscous and non-crystallizing measured media, with temperatures up to 150 °C, non-aggressive to copper alloys. The pressure gauge can be operated at an ambient temperature of -60 °C to +60 °C. The increased case diameter (250 mm) and a large, clear scale allow you to read readings at a great distance from the device. The accuracy class of pressure gauges of this series is 1.5. Degree of protection corresponds to IP40. Devices have radial accession. Scope: heat supply systems, heat power facilities.
