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 supplied accessories.

GENERAL DESCRIPTIONGENERAL DESCRIPTION

GENERAL DESCRIPTION

GENERAL DESCRIPTIONGENERAL DESCRIPTION

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. measurements. 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 temperature 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 allocates memory space to store up to 8000 measurements. 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.

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 9261 on, press ON/OFF.

To maximize battery life, the display is automatically switched off after 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.

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 instrument must be turned off until moisture has completely evaporated. In order to accelerate the evaporation process, the humidity sensor 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 temperature 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.

RANGE

1110

If neither a temperature probe nor a calibration test plug is connected, the meter will display on the primary display and print "----" to alert the user. This could also indicate 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.
