GENERAL DESCRIPTION

HI 8564 and HI93640 portable Thermo-Hy-

grometers measure both Temperature and
Relative Humidity.

HI93640 is a compact, easy to carry meter
with a convenient wrist-wrap. The built-in
thin film capacitance sensor assures accu­rate humidity measurements from 5.0 to

95.0% RH with a resolution of 0.1%.
The RH probe contains both the sensor and

the electronic circuitry necessary to amplify
the RH as well as the temperature read­ings. Another electronic circuit converts the
amplified signal into a digital readout in %
Relative Humidity.

Note: The RH probe sensor must never

come into contact with water or
other liquids.

HI8564 comes supplied with: HI70601/2,
detachable relative Humidity probe and a
9V battery.

HI93640 comes supplied with a 9V battery.

OPERATIONAL GUIDE

INSTRUMENT PREPARATION

Each meter is supplied complete with a 9V
battery. Slide off the battery compartment
cover on the back of the meter (see page 12),
unwrap the battery and install it.

To prepare HI8564 for use connect the RH
probe to the DIN socket on the top of the meter.

Using the HI8564 or HI93640 thermo-hy­grometer is simple. However, the recommen­dations below should always be followed.

be removed. Whenever the probe is to be
used in a dusty or smoky environment, the
filter must be kept on at all times.

TEMPERATURE MEASUREMENTS

Simply press the °C or °F keys to take the
temperature readings directly from the same
probe.

Note: Press °C key to display
the temperature in °C.

"°C" is displayed when mea­suring temperature in degrees
Centigrade.

EXAMPLE: A temperature
reading taken in degrees
Centigrade would read:

°C

RELATIVE HUMIDITY MEASUREMENTS

• 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
the liquid has evaporated completely. In
order to accelerate the evaporation pro­cess, the humidity sensor could be exposed
to a current of air.

For HI93640 only: in order to obtain a
faster response, the sintered filter should

CALIBRATION

All Hanna hygrometers have been
precalibrated at the factory.
Hanna Instruments uses state-of-the-art ther­mal humidity chambers for this purpose.
It is generally recommended to have all
hygrometers recalibrated at least once a
year.

For an accurate annual recalibration, con­tact your nearest Hanna Service Center.

You can also check the status of your
HI8564 and perform a quick recalibration
(with an accuracy of ±5%) by using the
Hanna mini-calibration cham­bers HI 7101.

The kits are composed of two

each one equipped with a

• When the salt has dissolved

completely, add all the con­tent of the second bottle of
HI 7111.

• Allow the solution obtained
to cool, and then pour it into
the chamber marked
"RH 11.1%", making sure
that no residue remains on
the walls of the glass con­tainer.

BATTERY REPLACEMENT

9 VOLT BATTERY

SHOCKPROOF RUBBER BOOTS

Battery replacement must only take place in a
non hazardous area using the battery types
specified in this instruction manual (see
page 14).

FOR HI93640 ONLY:

When the battery is rundown
"V" is displayed on the LCD to
warn the user.

HI93640 employs the ad­vanced "BEPS" technology.
BEPS will detect a low power
condition and will shut the dis­play off. If the ON/OFF but­ton is pressed again, the
meter will shut off after a few seconds.
When this occurs, replace the 9V battery
with a new one.

When the battery is exhausted or the instru­ment cannot be switched on, simply slide
the battery cover off from the rear of the
instrument and replace with the 9V battery
with a new one.

FOR HI8564 ONLY:

When the battery is run down

Recommendations for Users

Before using these products, make sure that they are entirely suitable for the environment in which
they are used.

Operation of these instruments in residential area could cause unacceptable interferences to radio and
TV equipments, requiring the operator to take all necessary steps to correct interferences.

In HI8564 the trimmers are sensitive to Electrostatic Discharge. It is recommended to use an
antistatic screwdriver during calibration.

Any variation introduced by the user to the supplied equipment may degrade the instrument's EMC
performance.

To avoid electrical shock, do not use these instruments when voltages at the measurement surface
exceed 24VAC or 60VDC.

To avoid damages or burns, do not perform any measurement in microwave ovens.
