  • Gas density monitors and gas density sensors for SF6 and

    Trafag gas monitoring devices measure the gas density directly, i.e. SF6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF6 Gas Density Sensors, or by combining both principles, i.e.SF6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF6 gas density.
