TABLE OF CONTENTS
HI 8564 and HI93640 portable thermo-hygrom-
eters provide reading with high precision in a
very short time for both RH (Relative Humid-
ity) and temperature.
HI93640 is a compact, portable and versatile
instrument to monitor relative humidity any-
where. The built-in thin-film capacitance sen-
sor assures accurate measurements from 5
to 95% RH with a resolution of 0.1%.
Note: The RH probe sensor must never
come into contact with water or
other liquids.
HI8564 is supplied complete with HI70601/2
RH probe, 9V battery and instructions.
HI93640 is supplied complete with probe sin-
tered cap, 9V battery and instructions.

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 hy-
grometers 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 HI 8564
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
thermally isolated chambers,
each one equipped with a
threadedcapandthreebottles
containing the appropriate
precalibrated saturated salts
toproduceaknownRHvalue.
Preparing the Calibration Solutions(HI8564
only)
• Pour approximately 26 cc of
distilled water into a glass
container.
• Immersethiscontainerintoa
bath of ice and water and
shakebriefly.
• Slowly add the contents of
a HI 7111 bottle containing
LiCl into the glass container
while continuing to shake.

OPERATIONAL GUIDE
INITIAL PREPARATION
Each meter is supplied complete with a 9V
battery. Slide off the battery compartment
cover on the back of the meter (see "Battery
Replacement"section),unwrapthebattery and
install it.
To prepare HI8564 for use, connect the RH
probetotheDINsocketonthetopofthemeter.
Turn the meter on by pressing the ON/OFF
button.
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.
•Intheabsenceofairmovement,theresponse
canbeacceleratedbymovingtheprobe.
• The probe sensor must never come into
contact with water or other liquids.
If this happens, or if condensation causes
dropsto form onthesurface ofthehumidity
sensor,turntheinstrumentoffand waituntil
theliquidhasevaporatedcompletely.Inorder
to accelerate the evaporation process, ex-
pose the humidity sensor to a current of air.
For HI93640 only: for a faster response,
remove the sintered cap. Whenever the probe
is to be used in a dusty or smoky environ-
ment, the cap must be kept on at all times.
TEMPERATURE MEASUREMENTS
Simply press the °C or °F keys to display the
temperaturereading.
WhenmeasuringtemperatureindegreesCen-
tigrade, "°C" is displayed.

RH Calibration Procedure (HI 8564 only)
• Bring the calibration kit to a temperature of
approximately 20°C.
• Remove the cap from the
"RH 11.1%" chamber con-
taining the LiCl solution and
insert the probe paying at-
tention not to tip it into the
liquid.
• Remove the adhesive sticker which covers
the calibration trimmer access holes.
• Press the ON/OFF key to
switch the instrument on.
• Waitforthemeasurementto
stabilize (this takes about
4 hours).
• Turn the low humidity trimmer (see Func-
tional Description) until a value of 0.0% is
seenonthereadout(readingbetween0.0%
and 1.0% RH is also acceptable).
• Removetheprobeandtightlysealthecham-
ber containing the LiCl solution.

• Whenthesalthasdissolved
completely, add all the con-
tent 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 con-
tainer.
• Seal the chamber well when not in use, as
the LiCl solution is extremely hygroscopic
andtends tocapturethe humidity presentin
the air causing the solution to expand in
volume and to overflow from the container.
• Pourapproximately12ccof
distilled water into the other
chamber marked "RH
75.4%".
• Add all the content of the
HI 7121 bottle containing
NaCl while continuously
shaking the container to
avoidtheformationoflumps.
Sealthiscontainerwellwhen
not in use.
The calibration kit needs
4 hours for stabilization.

BATTERY REPLACEMENT
Battery replacement must only take place in a
safeareaandusingthebatterytypespecifiedin
this instruction manual.
FOR HI8564
When the battery becomes
weak, the "V" symbol is dis-
playedontheLCDtowarnthe
user.
In order to replace the bat-
tery,simplyslideoffthecover
and replace the 9V battery
with a new one.
FOR HI93640
Whenthebatterybecomesweak,the"V"sym-
bol is displayed on the LCD to warn the user.
HI93640 is provided with the advanced BEPS
(Battery Error Preventing System) technol-
ogy, that turns the meter off when a low
power condition is detected. It is recommended
to replace the 9V battery with a new one.
When the battery need to
be replaced, simply slide off
the battery cover and install
a new 9V battery.

• Remove the cap from the
"RH 75.4%" chamber con-
tainingtheNaClsolutionand
insert the probe.
• Waitforthemeasurementto
stabilize (approximately
4 hours)
• Turn the high humidity trimmer until the
readout on the display is 64.3%.
• Wait for 1 hour and readjust if necessary.
• Leaving the probe in the "RH 75.4%" cham-
ber,adjustthe low humiditytrimmeruntilthe
value of 75.4% is read.
• Now, the humidity calibration is complete.
Spare saturation salts are also available:
HI 7111/P (LiCl) for low range humidity, and
HI 7121/P (NaCl) for high range humidity.

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
unacceptableinterferencesto radioandTVequipments,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 calibra-
tion.
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 24 Vac or 60 Vdc.
To avoid damages or burns, do not perform any measurement in
microwave ovens.
