PRINCIPLE OF OPERATION
The HydroSensor Moisture Probe is designed to detect mois-
ture in carpets, cushion, floors, walls, and furniture. When the
probe tips on the HydroSensor are pushed into materials to
penetrate the surface, an electric current is sent between the
probes. The amount of moisture present in the material deter-
mines how easily the electrical current passes from one probe
to the other.
When moisture is present in a material, the light on the Hy-
droSensor will flash and the transducer will beep. This will oc-
cur at a varying rate (slower or faster flash and beep) depend-
ing on the amount of moisture present.
The 7/8” probe tips are long enough to penetrate shag carpets,
cushion, and flooring materials. With care, the HydroSensor
can also be used to find moisture in furniture, walls, and ceiling
materials.
The HydroSensor will also detect the presence of urine resi-
dues in carpet and cushion. This is because urine salts attract
and hold enough moisture to be detected. A black-light is rec-
ommended to confirm that urine is present.
MODELS
Both Models
1. To expose the sensor points, loosen the black plastic
knob. Push it down and around the “J,” then tighten to lock
in position.
2. Test the unit by placing your fingers across the shaft of the
points and observing the response of the unit.
3. Probe the suspected moisture area with the points.
Flashing and beeping indicates that carpet and/or pad are
wet.
