SAFETY INFORMATION
The nickel plated points on the HydroSensor are extremely
sharp. Take care when collapsing the telescoping tubes, to
avoid the points extending by accident. This could cause injury.
Retract the probe points into the shaft when not in use.

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.
HydroSensor
The HydroSensor has a single, non-telescoping shaft.
HydroSensor II
The HydroSensor II has a 3-part telescoping shaft.
1. To extend the HydroSensor II, grasp the smallest tube and
pull until the spring button pops into place. If the tubes do
not extend easily, make sure the knurled knobs are loose.
2. Tighten both knurled knobs, to make sure the telescoping
tubes remain unbending.
3. Do not exert too much force when using. Excess force
may damage the tips or telescoping tubes.

MAINTENANCE
Clean and dry the HydroSensor after each use.
Battery Replacement
The HydroSensor is operates on the current from one 9-volt
battery. Battery life depends on usage and storage care. Do
not allow probe tips to stay in contact with metal, damp cloth,
carpet, water, cork or any other materials that will conduct
electricity. The battery is contained inside the handle below the
indicator light.
1. Remove the small screws which hold the handle halves
together, and gently split apart the handle.
2. Remove the old battery from its connectors and replace
with a new Eveready general-purpose 9-volt battery No.
216 (or comparable).
3. Reinsert battery into handle, taking care not to pinch any
wires.
4. Align the holes of the handle halves and replace the
screws. Do not over-tighten screws.
Note: Probe tips may be sharpened with a file. If points need
replacement because of excessive wear, contact Dri-Eaz
Products for a replacement HydroSensor Point Set Kit.
Other Moisture
Detection Tools
WetChec ✔
The WetChec✔ is a moisture probe similar in operation to the
HydroSensor, since it beeps when its probes contact moisture
or urine. It is an inexpensive marketing tool that contractors
give to customers on their restorative drying jobs, insurance
adjusters, property managers, and other clients.
Moisture Counter Non-Destructive Meter
Use the Moisture Counter for quick measurements when doing
preliminary inspection to determine if moisture is present. The
Moisture Counter allows you to rapidly evaluate where mois-
ture is a problem without penetrating the material's surface. It
also helps you to be positive when materials are completely
dry and returned to original condition.
Moisture PRO Penetrating Meter
The Moisture PRO is a hand-held penetrating instrument de-
signed to very accurately measure moisture content in wood,
drywall and other porous building materials. It is portable, bat-
tery powered and pocket sized, incorporating the latest elec-
tronics in a durable yet lightweight aluminum housing. The
Moisture PRO digital LCD gives moisture readings in wood
from 7% to 42% in 0.1% increments. A choice of interchange-
able electrodes is available including a shallow penetration,
hammer type and deep wall type.
