RH Systems 973-SF6 Analyzer

RH Systems Model 973-SF6 Analyzer

For measurement of humidity and SF6 purity in gas insulated switchgear systems

The RH Systems Model 973-SF6 Analyzer is expertly designed to measure humidity and SF6 purity in gas-insulated switchgear systems. This advanced analyzer presents humidity measurement data in ppmv, ppmw, and dew/frost point, available at either system pressure or standard pressure. Purity measurement is directly displayed as % volume SF6. Both humidity and purity measurements utilize precise and reliable condensation techniques, ensuring accurate and dependable results.

Advanced Gas Recovery System

The RH Systems 973-SF6 Analyzer is equipped with a sophisticated gas recovery system that securely stores the sampled gas during the measurement process in its internal storage tank. Once the measurement is complete, the stored gas can be efficiently pumped back into the original compartment or transferred to another container. This feature not only conserves gas but also minimizes environmental impact. Additionally, the system records starting and ending pressures, providing a comprehensive overview for effective gas management. This ensures that the integrity of the gas is maintained throughout the process, promoting safety and operational efficiency. With its robust design and cutting-edge technology, the RH Systems 973-SF6 Analyzer stands as a vital tool for maintaining the optimal performance of gas-insulated switchgear systems.
