sulfur hexafluoride Recovery pressure
Typical ApplicationMeasurement PrincipleStandard VersionStandard EquipmentOther VersionsOptions and AccessoriesA typical application of this instrument is the spot measurement in sulphur hexafluoride (SF6). Measurements are made at pressures between 10 mbar and 10 bar (1 kPa to 1 Mpa). Sample gas flow is effected by pressure difference between gas inlet and outlet, with a minimum of 10 mbar (1 kPa). If sample gas pressure is too low or the gas has to be measured in a closed circuit, an optional gas pump is available.See more on rhsAccuracy: < 0,2&C, 1 digit (standard)Readout: Digital, 3½ digitsAnalog Output: 10 mV/&C, 0&C = 0 mV, mA optionalReproducibility: < 0, 1&C, 1 digitDewpoint Instrumentation for Gases | Alpha Moisture Systems dew point2021/8/27Model DS2000 Single Channel Dew Point Hygrometer.
