973-SF6 Datasheet
The RH Systems Model 973-SF6 Analyzer is designed for measurement of dew point (moisture content) and Sulfur-hexafluoride (SF6) purity via the chilled mirror technology. High accuracy minimizes costly reading mistakes and ensures consistent readings. SO2 measurement for decomposition product indication. Pump back feature ensures that no SF-6 Gas will be discharged into the atmosphere. Sample test hose and the most common DN8 and DN20 fittings are included with the device. Alternative fittings are available in a kit to suit almost any application.
