Hydrostatic Interstitial Brite™ Sensor (HIS)

The hydrostatic interstitial Brite™ sensor (HIS) detects leaks in double wall tanks where the interstitial space is filled with a liquid brine solution. For use with all EVO™ Series fuel management systems, the HIS polyester, Nitrile, and epoxy construction is compatible with all types of brine.
