Due to the above reasons, SF6 is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin SF6. ENERVAC produces a complete line of SF6 recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.

The Rapidox SF6 6100 Portable is designed for controlling and monitoring the quality of SF6 in MV HV gas insulated electrical equipment. Exceptional accuracy and stability are provided when measuring the purity of SF6 gas, through specially selected sensors.

Micafluid sf6 mixture Calibration in Syria. Sulfur hexafluoride has no lower and upper explosive limits but can severely react with disilane and form a dangerous explosive gas mixture. SF6 easily hydrolyses into fluorinated compounds in water (thionyl fluoride and hydrogen fluoride) that are extremely toxic and corrosive substances.
