SGB - Model DL 290, 230VAC, pl-box, H4+H6 -Pressure Leak Detector

Pressure leak detector (DL) with 290 mbar alarm pressure for above and underground double-walled tanks up to max. 2,6 meter diameter and 450 mbar minimum test pressure of the interstitial space. For the monitoring of water-polluting liquids of those the (possible) explosive vapor-air mixtures (also such ones that can arise through the stored/conveyed liquids in contact with air, humidity, condensation or the materials used) must be classifiable into gas group II A to II B3 as well as in the temperature code T1 to T3, for example: petrol.
