SGB DL 280 8S Pressure Leak Detector – 230 VAC, Plastic Housing (QU8/6)
The DL 280 8S is an advanced pressure leak detector designed to monitor double-walled underground tanks for water-polluting liquids—including fuels and solvents. It operates by maintaining overpressure in the interstitial space, triggering both visual and audible alarms on pressure drops. The “8S” variant adds integrated monitoring of up to eight sumps or ancillary chambers via leak sensors (sold separately).
