Water Level Sensor, 100 dB High or Low Sump Pump Alarm, 79in Cable

SWITCHABLE HIGH OR LOW LEVEL ALERTS：Set the float sensor for one monitoring mode at a time. Low-level mode alerts when water falls below the selected point; reverse the float for high-level mode to warn when water rises too far, helping you respond before pump dry run or overflow causes damage.
LOUD LOCAL ALARM, NO WIFI REQUIRED：The water level alarm sounds up to 100 dB and offers 4 volume settings, including mute. It works independently without an app, hub, internet connection, or subscription, and the alarm can be paused for 10 seconds with a quick button press.
78.7 INCH EXTRA-LONG DETECTOR CABLE：Keep the alarm unit in a dry, easy-to-hear location while positioning the float sensor at the water level you need to monitor. The 6.5 ft cable provides flexible placement in deep tanks, sump pits, aquariums, pools, and cisterns.
BATTERY POWERED WITH LOW-BATTERY REMINDER：Powered by 2 AAA batteries for flexible installation without a nearby electrical outlet. The battery-operated design continues monitoring during power interruptions, while the low-battery reminder lets you know when replacement is needed.
BUILT FOR WATER LEVEL MONITORING：Use this water level detector for sump pump pits, water tanks, aquariums, swimming pools, cisterns, and other containers. It monitors a selected high or low threshold; this local alarm does not measure exact water depth or send phone notifications.
