SF6, Sulfur Hexafluoride | Concorde Specialty Gases, Sulfur Hexafluoride . Sulfur Hexafluoride (SF6) is an inorganic, colorless, odorless, and non-flammable gas. SF6 primary use is in the electrical industry as a gaseous dielectric medium for various voltage circuit breakers, switchgear and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.
Digital Ohmmeter Schematic | Products & Suppliers ..., Inc. Digital Microohm and Bond Meter There are two models of the R1L-B series: the BR model is more suitable for portable "rugged" applications while the B model is suitable mainly for "in plant" environments. Both instruments utilize the four-terminal Kelvin technique to eliminate errors caused by the resistance of the connecting cables.
Sulfuryl fluoride - Wikipedia fluoride (also spelled sulphuryl fluoride) is an inorganic compound with the formula SO 2 F 2.It is an easily condensed gas and has properties more similar to sulfur hexafluoride than sulfuryl chloride, being resistant to hydrolysis even up to 150 °C. It is neurotoxic and a potent greenhouse gas, but is widely used as a fumigant insecticide to control termites
