Sulfr hexafluoride gas - WIKA South Africa

The plant safety of SF 6 gas-insulated switchgear is reduced significantly through low concentrations of decomposition products. These decomposition products arise during operation through arcing in moist or impure SF 6 gas. In order to detect even the smallest leakages or to warn ahead of gas emissions, we have a range of high-quality gas detectors and emission monitors.Get price
