SF6 Gas Density Monitor 87x8

For Arctic Temperatures

Trafag SF6 gas density monitors use a unique gas density reference principle. The technique is very resilient to temperature changes and the robust design is not subject to wrongful switching (contact bouncing) due to vibrations or shocks.

87×8 is designed for extremely low temperatures with exact temperature independent switches.
