Remove the instrument from the packing material and examine it
carefully to make sure that no damage has occurred during shipping.
If there is any damage, notify your Dealer or the nearest Hanna
Customer Service Center.
Each printing thermohygrometer is supplied complete with:
• Relative Humidity Probe (HI 70604/2)
• Temperature Probe (HI 762L/2)
• 1.5V AA Size Batteries (4 pieces)
• Non-fading Printer Paper (5 rolls)
• Rugged Carrying Case
Note: Save all packing material until you are sure that the
instrument functions correctly. Any defective item must be
returned in their original packaging together with the sup-
pliedaccessories.
HI 9161, HI 9261 and HI 91610 are portable, microprocessor-based
printing/logging thermohygrometers.
The housing is made of rugged, lightweight material, making them
truly portable. HI 9261 has been specifically designed by Hanna
Instruments for use in the food industry.
The meters come equipped with a large, easy-to-read LCD.
Measurements can be performed with lab-grade precision in the field
as well as in the laboratory without compromising accuracy.
For prolonged field and lab applications, these meters can be
connected to a 12VDC adapter.
The interchangeable relative humidity probe contains both the sensor
and the electronic circuitry necessary to amplify the R.H. measure-
ments. Another electronic circuit converts the signal sent by the probe
into a digital readout in % Relative Humidity. The standard cable is
2 meters (7') long, and a 5 meter (16.5') version is also available.
Note: the RH probe sensor must never come into contact with water
or other liquids.

For special applications, HI 70606/2 or HI 70606/5 RH probes can
also be used. These probes come with a sintered cap on the sensor
shaft for protection in dusty or corrosive environments.
An independent temperature probe provides highly accurate tem-
perature readings.
While in logging mode, HI 91610 stores the measurements into
memory at a user selected interval from 1 to 180 minutes. The data
can be retrieved at a later date for printing or can be transferred to
a computer through the HI 9200 transmitter. The internal software
allocatesmemoryspacetostoreupto8000measurements. HI 91610
will transfer the data in seconds through the infrared lights with no
need for a cable between the transmitter and the meter.
Two versions of each instrument are available:
•HI 9161C, HI 9261C and HI 91610C are thermohygrometers
with temperature readings in Celsius;
•HI 9161F, HI 9261F and HI 91610F are thermohygrometers
with temperature readings in Fahrenheit.

RELATIVE HUMIDITY MEASUREMENTS
Using the HI 9161, HI 9261 and HI 91610 thermohygrometers is
simple. However, the recommendations below should always be
followed.
•The sensor end of the humidity probe 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 back and forth.
•The probe sensor must never come into contact with water or any
other liquid. If this should happen, or if condensation causes
drops to form on the surface of the humidity sensor, the instru-
mentmustbe turned offuntilmoisturehascompletely evaporated.
Inorder toaccelerate theevaporation process,the humiditysensor
should be exposed to a current of air.
If you experience any problems in taking measurements, please
contact your Dealer or the nearest Hanna Customer Service Center.
TEMPERATURE MEASUREMENTS
The HI 762L/2 temperature probe supplied with the HI 9161,
HI 9261 and HI 91610 is a liquid/general purpose probe with 2 m
(6.6') cable.
Simply plug the probe into the socket located on the top of the meter
(refer to Functional Description on pages 5 to 7).
If it is necessary to monitor temperature continuously, keep the probe
attached to the meter at all times.
To view either the RH% or temperature read-
ing on the display, press RANGE. The reading
will appear without decimal digit when shown
on the lower secondary display. The tempera-
ture range on the secondary display is from 0
to 99°F (or °C).
If the temperature exceeds this range "--" will
appear indicating that the small portion of
the display is unable to accommodate the
reading.

"----"toalert theuser.This couldalsoindicate
that the probe cable is damaged.
Hanna offers a wide range of temperature probes to meet all
temperature measurement requirements. Hanna probes use highly
sensitive thermistor sensors which provide greater accuracy and faster
response than conventional thermistor probes.
Hanna temperature probes are supplied pre-calibrated from the
factory and are ready to use.
Available in four different handle colors to avoid cross contamination
during testing, these completely interchangeable probes make it
possible to switch from one to another without needing to recalibrate
the meter (see pages 34-35 for a complete listing).
In order to keep accurate records of temperature, your monitoring
equipment must be properly re-calibrated. Hanna Calibration Test
Plugs provide a quick and easy way to test the meter's accuracy. If
the reading differs by more than ±0.4°C (±0.8°F) from the Test
Plug value, the unit is due for re-calibration and you should contact
your Dealer or the nearest Hanna Customer Service Center.
See page 36 to choose the right Test Plug to suit your needs.

• 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 hygro-
scopic and tends to capture the humidity
present in the air causing the solution to
expand in volume and overflow from the
container.
• Pour approximately 12 cc of distilled wa-
ter 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 avoid the for-
mation of lumps. Seal this container well
when not in use.
The calibration kit needs 4 hours for proper
stabilization.
CALIBRATION PROCEDURE
• Bring the calibration kit to a temperature of approximately 20°C
and keep it in an area with minimum amount of temperature
variations.
• Remove the cap from the "RH 11.1%"
chamber containing the LiCl solution and
insert the probe paying attention that it
does not come in contact with the liquid.
• Remove the adhesive sticker which covers
the calibration trimmer access holes.
• Wait for the measurement to stabilize
(this takes approximately 4 hours).

All Hanna thermohygrometers have been precalibrated at the factory.
Hanna Instruments uses state-of-the-art thermally-isolated humidity
chambers for this purpose.
Itisgenerallyrecommendedtohaveallthermohygrometersrecalibrated
at least once a year.
For an accurate annual recalibration, contact your dealer or the
nearest Hanna Customer Service Center.
You can also check the status of your thermohygrometer and perform
a quick RH recalibration (with an accuracy of ±5%) by using the
optional Hanna HI 7101 mini-calibration chamber.
The kit is composed of two thermally-isolated
chambers, each one equipped with a 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 wa-
ter into a glass container.
• Immerse this container into a bath of ice
and water.
• Slowly add the contents of a HI 7111
bottle containing LiCl into the glass con-
tainer while stirring gently.
• Whenthesaltshavedissolvedcompletely,
add all the content of the second bottle
of HI 7111.

Capacity: 8000 data samples which are divided into 16 pages.
Capacity per Page: up to 500 data.
Each time a new logging mode is entered, the meter automatically goes
to the next available page. Once all 16 pages are used up, the meter
will overwrite the first lot. During logging, the meter automatically
returns to the oldest page in the memory and if it contains data, it will
overwriteit. In this case the first log will notcorrespond tothe oldestset
of data. It is recommended to periodically “clean” the memory. Save
data into a PC if you need to keep a record and then disconnect the
batteries for about 1 minute. If you do this, remember to reset the time
and date, once the batteries have been reinserted again.
ATTENTION
Data is stored into memory until batteries are removed. If replace-
ment of the batteries is needed and data is not to be lost, first plug
in an external 12VDC power supply and then proceed with battery
replacement as described on page 33. Only once batteries have been
replaced, it is possible to unplug the power supply without losing the
previously memorized data.
