product overview

Used for monitoring sealed containersSF6The density of gas can be displayed on site, and an alarm will be triggered when the density value reaches the set value. It is suitable for detecting high-pressure systems. We can provide various solutions such as supporting new substations and intelligent transformation of existing substations.
