Unique SF6 monitoring with reference gas comparison

The Gas Density Monitor functions on the principle of reference gas comparison and therefore does not require
temperature compensation.

It is much more accurate than bimetal compensated pressure  gauges and it is extremely vibration and shock resistant. Since no recalibration of switch points is needed, it operates maintenance-free.

Since no recalibration of switchpoints is needed, it operates maintenance-free. The operating temperature ranges are from –60 °C up to +80 °C.
