  • 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.
