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.

HI 9161C

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.

OPERATIONAL GUIDEOPERATIONAL GUIDE

OPERATIONAL GUIDE

RANGE

Each meter is supplied complete with 4 x 1.5V common AA batteries.

Unscrew and remove the back cover, unwrap the batteries and install

them while paying attention to their polarity.

Connect the RH probe to the 7-pin DIN socket on the top of the meter

and fasten the threaded ring tightly. Connect the temperature probe

to the appropriate connector. The temperature probe can be used

independently to take temperature measurements, or it can be used

in conjunction with the RH probe.

If neither the RH nor the temperature probes

are connected, "----" will appear on the LCD.

To switch the HI 9161 and HI 9261on, press

ON/OFF.

To switch the HI 91610 on, press RANGE.

Tomaximizebatterylife,the displayis automaticallyswitchedoffafter

5 minutes of non-use. However, the meter will continue to monitor

(when in the recording/logging mode) RH and temperature.

To reactivate the display, press RANGE.

If neither a temperature probe nor a calibra-

tion test plug is connected, the meter will

display on the primary display and print

"----"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.
