GENERAL DESCRIPTION

The HYGROCHECK is a lightweight,
pocket-sized tester designed for on-the­spot testing of relative humidity.

The rugged ABS housing has a built-in
LCD that displays the reading in large
digits.

Measurement are simple with
HYGROCHECK. Just turn it on, wait a
few seconds, and read the display. The
relative humidity is expressed in percents
of 100 (10%-90%).

NOTE:

The RH probe sensor must never come
into contact with water or other liquids.

USING THE INSTRUMENT

CALIBRATION

SPECIFICATIONS

Using the HYGROCHECK is simple.
However, the recommended procedure is
as follows:

• The end of the humidity detector
should be exposed to a current of air
moving at 0.5 m (20") per second or
more.

• In the absence of air movement, the
response can be accelerated by mov­ing the probe.

• The probe sensor must never come
into contact with water or other liq­uids. If this should happen, or if
condensation causes drops to form
on the surface of the humidity sen­sor, turn off the instrument and wait
until this water has evaporated com­pletely.
In order to accelerate the evapora­tion process, the humidity sensor
could be exposed to a current of air.

If you experience any problems in taking
measurements, please contact your
dealer or the nearest Hanna Instruments
Customer Service Department.

All Hanna hygrometers are calibrated with
reference to NIST certified instruments.
In addition, the Hanna Service Centers
are equipped with state-of-the-art cali­bration chambers. For an accurate
recalibration of your meters, contact your
nearest Hanna Service Center.
