Johnson Pump Bilge Water Alarm 12V

The water level alarm uses new digital technology - the patented MIRUS field effect. The protected cells detect a break in the electrical field caused by water or liquid. The sensors are fully protected and never come into contact with water. They do not oxidize and are not affected by oil or debris. The bilge water alarm detects water and warns with a loud signal sound (90 db). The alarm can be tested, deactivated and activated using a three-position rocker switch.
