RH Systems 973
RH-973-SF6 Portable Gas Analyzer is specifically designed for measurement of
humidity and SF6 purity in gas insulated switchgear systems. Humidity
measurement data is displayed in ppmv, ppmw and dew/frost point at either
system pressure or standard pressure. Purity measurement is displayed directly
in % volume SF6. Both the humidity and purity measurements utilize accurate
and reliable condensation techniques.
The 973-SF6 is equipped with a gas recovery system that stores the sampled gas
during the measurement process in its internal storage tank. After completion
of the measurement, the stored gas may be pumped back into the original
compartment or into another container. Starting and ending system pressures
are also measured.
