insulating gas - Analytical and Control Technology 2000 Co., Ltd.

The monitoring of sf6 gas gas density in medium and high-voltage switchgear can thus be left to secondary technology. Our gas density monitors are hermetically sealed and temperature-compensated. Measured value fluctuations and misinterpretations caused by changes in either ambient temperature or atmospheric pressure are therefore prevented.
