This inexpensive Liquid Alarm may be placed anywhere. The moment a solution touches the sensor, the alarm sounds and a red LED light flashes continually until the liquid no longer touches the sensor.
Place the sensor on the floor to detect spills. It allows taking action before a serious situation develops. A loud, high-decibel alarm sounds and a red LED light flashes until the sensor is removed from liquid. Constantly alarms for over 30 hours. Position the detector on an overflow tube or near a pump to alert you when an accident is occurring. Cable length is 10 feet.
Use with aqueous solutions and liquids that don’t attack plastic. Battery-operated alarm sounds even during power outages. Pays for itself by preventing just one ruined lab test. Size is 1-13/16 x 3 x 3/4 inches. Weight is 2-1/2 ounces. Supplied with 9V battery.
