      Provide a leak protection in and around secondary containment tanks and sumps with optical liquid sensors from Grainger. Interstitial leak detection switches can be horizontally mounted a tank wall or bottom of the sump. The flat profile and minimal float rise allows for mounting in tight spaces. The normally closed switch opens to alert when liquid is detected.
