SF6 Air Sensor Measurement for gis

SF6 Monitoring System - ENEIDA.IO. SF6 is an inert gas mixture with excellent dielectric properties, and it has been widely applied on very high voltage parts such as Gas-Insulated Switchgears (GIS) in order to reduce its size or increase the working voltage. SF6 also has a high contribution for the Greenhouse Effect so its use is deeply regulated.
