Description
The iSF6-1800S chilled mirror clean air multi-analyzer aims at the measurement of humidity, helium, oxygen and other component gases of the filling gas in GIS and other electrical switchgear after helium leak detection.

It is suitable for gas detection in switchgear (GIS) with clean air insulation technology. It can measure the concentration of oxygen, carbon dioxide and nitrogen in the switching gas chamber, and the residual amount of helium after helium detection. It can also detect the moisture of the gas, the pressure of the gas chamber, etc.
 
It uses high-precision electronic flowmeters for automatic flow control. Advanced chilled mirror technology is used to measure humidity, while customized sophisticated sensors, ensuring the He volume percentage analysis more accurate. It sets real-time measurement, power management, time management, file system, data management and many other functions in one, with the integration of international advanced sensor technology and information technology, friendly human-computer interaction touch interface, making it the ideal equipment for gas measurement.
