Product Description


Rectorseal - AquaGuardThe AquaGuard AG-1250E is a multipurpose water sensor that can be mounted directly on HVAC/R units, in a metal or plastic secondary drain pan, on floors or even on a wall.

The multipurpose water sensor features a clip on mounting base, which can be mounted with the included adjustable height clips, double sided adhesive tape, or a screw, for easy cleaning and drying of the sensor.

The AquaGuard AG-1250E is a high-amperage, solid state sensor, which features patent pending Smart Sensor Technology and contains no moving parts that could become clogged like competitors’ float sensors.
