Sulfur Hexafluoride Dew Point Meter

The sulfur hexafluoride (SF6) dew point meter detects the condensation temperature of water vapor in the gas by cooling a mirror surface, reflecting the dryness of the SF6 gas. It is used for monitoring the humidity of insulating gases in electrical equipment to prevent malfunctions caused by moisture.
Selection
When selecting, focus on a measurement range covering dew points from -80℃ to -20℃, with an accuracy within ±2℃. It must be compatible with SF6 properties, equipped with a pressure relief valve and a recovery interface. Consider an automatic mirror cleaning function to adapt to the on-site environment of substations.
