- The RH Systems Model 973-A Dew Point Mirror was specifically designed for measurement of humidity in gas insulated switchgear (GIS) systems. Humidity measurement data is displayed in PPMv, PPMw and dew/frost point at either GIS pressure or standard pressure. Based on the chilled mirror principle, the 973-A ensures direct and accurate humidity measurement with minimal gas loss.
- Full Color Touch Screen
- Easy, Automated Usage
- Verifiable Calibration
