Dometic Tank Monitor 8 (DTM08) monitors empty, low, mid, and full levels of any waste & freshwater holding tanks with assured accuracy, letting you know when it's time to discharge or refill tanks. A continuous light lets you know the power is on, and an optional relay can be added to shut off power to the toilet when the holding tank is full to prevent toilet system damage. Works with either 12 or 24V.
