About Sound Levels
To choose an alarm or speaker that’s loud enough, first determine the decibel (dB) rating of background noise.

Water Overflow Buzzers

When water contacts the sensor, it triggers a buzzer to alert personnel to a leak or overflow hazard. Frequently used to monitor sinks, pipe lines, tubs, and sump pumps.
Volume | Sound Pattern | Ht. | Wd. | Dp. | Cord Lg., ft. | Material | Batteries Included | No. of Batteries Required | Battery Size | Includes | Each | |
96 dB @ 1 ft. | Pulse | 3 1/4" | 2 1/4" | 7/8" | 5 | Plastic | No | 3 | AAA | Hook and Loop Mounting Tape | 0000000 | 000000 |
Wi-Fi Enabled Water Overflow and Freeze Detectors
Keep an eye on leaks, overflow, and temperature changes near your equipment, even when you’re offsite. These detectors connect to your Wi-Fi to send alerts about moisture, temperature, and humidity to your smartphone or tablet. Place them near tanks and tubs to watch for overflow, or near sump pumps and pipe lines to monitor temperatures and prevent frozen pipes. When water touches one of the sensors on the detector, a buzzer also goes off, alerting anyone nearby. Rated IP44, these detectors are protected from objects larger than 1mm, such as wires, and from water splashing in any direction.
Download an app onto your smart device to program temperature and humidity ranges and set up alerts. You can also create reports that show changes in temperature and humidity over time.
To extend the area they monitor, these detectors come with a detachable cable sensor that senses moisture along its entire surface. Swap in replacement cable sensors for worn sensors, or link several together to wrap around large equipment or trace the path of a pipe. Extend them up to 500 feet from detectors.

High Liquid-Level Alarms for Sump Pumps

An alarm and a red light alert you when water levels rise too high. A float detects water level and activates the alarm. Alarm has a plastic housing that meets NEMA 3R for protection from dirt, falling liquids, and light splashing.
Voltage | Volume @ Distance | Plug Type | Cord Lg., ft. | Environmental Rating | Each | |
120V AC | 82 dB @ 10 ft. | Three Prong | 20 | NEMA 3R | 0000000 | 0000000 |
Chemical-Resistant Vertical-Mount Liquid-Level Gauges for Tanks
With a stainless steel float and float rod, these gauges resist corroding from chemicals. Their indicator moves up as your tank fills. Check the indicator against the graduation marks to see how full your tank is and if you need to fill or drain it. Plastic protects the indicator's movement, saving you from inaccurate readings.
Alarms can be set to flash and sound at levels critical to your system.
Remote-reading displays let you check readings from up to 100 ft. away. They have an alarm that sounds when the level is too high or too low.
