Switching operations (i.e. discharges in SF6-filled equipment) lead to an increasing amount of moisture and highly toxic and corrosive decomposition products. These impurities impede the safe operation of switchgear. The WIKA GA20 SF6 Moisture-Humiditor Analyzer is a cost effective way to determine the level of moisture (H2O) in SF6-filled equipment to secure the safe operation and prolonged lifetime of electrical equipment.

WIKA GA20 SF6 Moisture-Humiditor Analyzer features:

• Polymer-based capacitive humidity sensor measuring principle
• Measuring range of -60 ... 20 °C dew point
• Accuracy of ±2 °C dew point at -40 ...+20 °C dew point and ±4 °C dew point at < -40 °C dew point
• 20 liters/hour
