SF6-alternatives Density Monitors

SF6-alternatives Density Monitors

Oct 29, 2018SF6 alternatives. Given its environmentally hazardous nature, viable alternatives to SF6 are currently being sought and tested for industrial use. The challenge is finding a gas with comparable insulating properties, similar material compatibility and a significantly lower greenhouse effect.

  • Gas density monitors and gas density sensors for SF6

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.
