General Information
GDSF-311WPD is ideal instrument when it is necessary to test water content, purity and decomposition products of SF6 gas. The core component of dew point test is DRYCAP series sensors produced by Finland Vaisala company. With professional hardware chips and excellent software algorithms of STMicroelectronics, we have produced a new generation of gas moisture test instrument.
Application
Technical parameters
SF6 Humidity:
Measuring range | Dew point -100 ~ +30 ºC(support ppmv, etc. ). |
Dew point accuracy | +-0.5degree (when the dew point temperature is below 0 degree, the sensor output for the frost point). |
Repeatability | +-0.5 degree. |
Gas flow | SF6 adjustment in 0.5 ~ 0.9L/min; |
Measuring range | 0 ~ 100% SF6 |
Accuracy and repeatability | +-0.5%, nothing to do with the flow |
