Sep 29, 2021The average monthly gas bill in the US is $63.34, though natural gas costs more in some states than others. Natural gas is used to warm your house, to keep the hot water running, and, in many instances, to cook. Reading your gas bill may feel like reading a science report, so let's get down to the most important acronym, BTU.
[email protected]SF6 concentration sensor for gas-insulated electrical switchgear The use of SF 6-N 2 gas mixtures in gas insulated electrical switchgear (GIS) is becoming more wide-spread. This is motivated by the reduction of environmental impact associated with SF 6 emission and the increasing number of GIS located in low temperature environments where pure SF 6 cannot be employed.
