GENERAL DESCRIPTION

HI 9064 and HI 9065 are heavy-duty hygrometers specially designed for
field applications such as HVAC.

They are housed in a rugged water-resistant case to provide maximum
protection in the field.

The relative humidity probe houses a thin-film polymer sensor, which
quickly performs all RH readings to 98% accuracy.

A “HOLD” key will instantly freeze the reading on the LCD.
HI 9065 can also measure temperature with an internal sensor in the RH

probe from 0 to 60°C as well as from 32 to 140°F.
You can also connect a separate temperature probe for gas and liquid

measurements (HI 765 series).

Note: The RH probe sensor must never come into contact with water

or other liquids.

OPERATIONAL GUIDE

INITIAL PREPARATION

Each meter is supplied complete with four 1.5V
AA batteries. Remove the back cover, unwrap
the batteries and install them while paying
attention to their polarity (see “Battery Re­placement” section for details).

Connect the RH probe to the DIN socket on the
top of the meter and fasten the screw tightly.

Note: HI 9065 can be used with just one

probe (RH or temperature) at a time.

RH (RELATIVE HUMIDITY) MEASUREMENTS

Turn the meter on by pressing ON/OFF.
Press the RH key to display the RH% measure-

ment. The "H" symbol on the display indicates
RH measurement mode.

ON/OFF

TEMPERATURE MEASUREMENTS (HI 9065 ONLY)

Connect the temperature probe (HI 765 series, see “Accessories”) to
the socket on the top of the meter and the unit will automatically
display the temperature reading.

Note: HI 9065 can be used with just one probe (RH or temperature)

at a time.

Press the “°C” key and the temperature value is displayed in degrees
Centigrade with the “°C” symbol.

°C

The same reading in degrees Fahrenheit is shown if the “°F” key is
pressed.

°F

For any problem in taking measurements, please contact your dealer
or the nearest HANNA Customer Service Department.

• For reliable 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 they have evaporated com­pletely. To accelerate the evaporation process, expose the humidity
sensor to a current of air.

HOLD FUNCTION

The reading HOLD function is activated by
the HOLD key.

The measured value is frozen on the display
when this function key is pressed. "S" is
displayed to indicate that the reading is also

stored.
Press the same key again to retirn to normal mode.

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 the
nearest Hanna Service Center.

You can also check the status of your hygrom­eter and perform a quick RH recalibration
(with an accuracy of ±5%) by using the
HANNA calibration chamber HI 7101.

The kit is composed of two thermally isolated chambers, both equipped
with a threaded cap and three bottles containing the appropriate
precalibrated saturated salts to produce a known RH value.

PREPARING THE CALIBRATION SOLUTIONS

• Pour approximately 26 cc of distilled wa­ter into a glass container.

• Immerse this container into a bath of ice
and water and shake briefly.

Seal this container well when not in use.

for stabilization.

CALIBRATION PROCEDURE

• Bring the calibration kit to a temperature of approximately 20°C.

• Remove the cap from the "RH 11.1%" cham­ber containing the LiCl solution and insert
the probe paying attention not to dip it into
the liquid.

• Remove the adhesive sticker which covers the
calibration trimmer access holes.

• Slowly add the contents of a HI 7111
bottle containing LiCl into the glass con­tainer while shaking.

• When the salts have dissolved completely,
add the content of the second HI 7111
bottle.

• Allow the solution to cool, and pour it into
the chamber marked "RH11.1%", mak­ing sure that no residue remains on the
walls of the glass container.

• Seal the chamber well when not in use,
as the LiCl solution is extremely hygro­scopic and tends to capture the humidity
present in the air causing the solution to
expand in volume and overflow from the
container.

HI 9064 and HI 9065 are provided with the advanced BEPS
(Battery Error Prevention System) technology that detects a low power
condition and automatically turns the instruments off to avoid
erroneous readings.

Battery replacement must only take place in a safe area and using
the battery type specified in this instruction manual.

To replace the batteries, simply remove the
two screws on the rear of the instrument
and replace all four 1.5V AA batteries with
new ones, while paying attention to the
correct polarity.

• The relative humidity calibration is now complete.
