RV Electronics LCD Double Tank Water Level Indicator Gauge – Black (12V)

Monitor two onboard water tanks with a bright, coloured LCD display. Built for caravans, RVs, motorhomes, camper trailers and boats, this RV Electronics gauge shows five clear water levels at a glance—and can stay on continuously thanks to its ultra-low 50 mA draw.

The kit includes 2 × 7.5 m sender probes. If you want the kit, please select the kit from the variants available above. A double-tank setup requires two probes—this kit has both included.
