Remove the meter from the packing material and examine it to
make sure that no damage has occurred during shipping. If there
is any damage, contact your local Hanna Instruments Office.

Each meter is supplied complete with:

• Temperature probe

• Alkaline batteries: 1.5V AAA (3 pcs.)

• Quick reference guide

• Instruction manual

Note: Save all packing material until you are sure that
the meter functions correctly. All defective items must
be returned in the original packing with the supplied
accessories.

PRELIMINARY EXAMINATION

The thermometers are waterproof and are rated IP65.
The meters are specifically designed for measuring

the temperature in all areas of the food sector.
Both air temperature and product internal

temperature can be measured with these thermometers.
The probe shaft is designed for continuous contact with foodstuffs

INTENDED USE

in accordance with Regulation (EC) 1935/2004.
Refer to the probe section of this manual for more information

on the available probes.

The process variable temperature plays a central function in food
commerce. Many aspects of safe food handling require the accurate
measurement of temperature. Food service, food preparation,
packaging, storage and transport of food require temperature
to be monitored or controlled. Spot checking temperatures with
Hanna food thermometers ensures daily work routines are carried
out at the correct temperature.
Hanna Instruments manufactures food thermometer models to
meet the tough environment encountered in the food sector.
Standard features of all models include a ruggedized professionally
designed waterproof case and stainless steel probe for measure‑
ments in semi solid foods, liquids, pastes or air. They provide
good accuracy and include features such as CAL Check, low battery
detection, auto‑off capability, and long battery life.
The model HI93501 is a thermistor style thermometer. It
measures temperatures from ‑50.0 to 150.0 °C (‑58.0 to

302.0 °F). It comes with a stainless steel replaceable style
penetration probe (FC762PW).
The models HI935001 and HI935007 thermometers utilize a
K‑type thermocouple style probe and provide the large range
of temperature measurement; from ‑50.0 to 300 °C (‑58.0 to
573 °F). The model HI935001 uses a replaceable style probe
(FC766PW) and the model HI935007 has a fixed thermocouple
probe and is not replaceable.
The models HI935004 and HI935008 thermometers utilize a
T‑type thermocouple style probe and provide the large range
of temperature measurement; from ‑50.0 to 300 °C (‑58.0 to
573 °F). The model HI935004 uses a replaceable style probe
(FC767PW) and the model HI935008 has a fixed thermocouple
probe and is not replaceable.
Models HI93501, HI935004 and HI935008 are compliant to
standard EN 13485.

section for more details).

OPERATIONAL GUIDE

Battery Life

TAKING MEASUREMENTS

Connect a suitable temperature probe to the meter (see page
21 for a complete list of Hanna Instruments probes).

OPERATIONAL GUIDE

Note: HI935007 and HI935008 have a fixed probe.

To switch the meter ON, press the ON/OFF button on the front
of the meter. If it does not turn on, make sure that the batteries
are properly installed in their place.

At start‑up the thermometer displays all LCD segments for a few
seconds, followed by the percentage indication of the remaining
battery life. It then enters CAL Check mode followed by measurement
mode.

HI93501

CALIBRATION CHECK

All the models are provided with an automatic CAL Check
feature at start‑up, which allows the user to check the meter
calibration status.

If the meter is calibrated, the display will stabilize and show
“0.0 °C” (±0.3 °C) for a few seconds.

MEASUREMENT

If a temperature probe is plugged in, the meter displays the
measured temperature.

If the measurement is unstable, the meter will display ⌛ until
the measurement becomes stable.

17

If the reading is slightly beyond the measurement range, the
meter flashes the closest full‑scale value.

E.g.HI93501

To switch the meter OFF, press the ON/OFF key.

If no temperature probe is plugged in, or the signal is interrupted
the display shows blinking dashes and the “NO PROBE” message

Enter Setup Mode to change the temperature unit (°C or °F) or
to adjust the auto‑off time. To enter the Setup Mode, press the

SET button located inside the battery compartment.

NO PROBE message

If no temperature probe is plugged in, or the signal is interrupted
the display shows blinking dashes and the “NO PROBE” message
is displayed.

DAMAGED PROBE message

When the readings are very far from the measurement range,
the probe may be damaged. The display shows blinking dashes
and “NO PROBE” message is displayed.

CALIBRATION CHECK ERROR MESSAGE

If during CALIBRATION CHECK the meter displays more than
±0.3 °C, then an “Err” message is displayed.

• Use the ON/OFF button to switch between “°C” or “°F”.
Long press the ON/OFF button once to save and continue
to auto‑off settings.

• Use the ON/OFF button to cycle through the following
Auto-Off choices: 8 minutes (“d08”, default value),
60 minutes (“d60”) or OFF (“d---”). Long press the
ON/OFF button once to save and continue to normal
operation.

8 minutes 60 minutes Disabled

Contact your local Hanna Instruments Office for recalibration.

18

Each model is provided with an auto‑off feature, which
switches the meter off after a certain period of non‑use, to
save battery life.

19

BATTERY REPLACEMENT

When the remaining battery life is less
than 10% the battery tag blinks on the
display to warn the user.

If the display shows battery level “0%” it means the battery
charge is not enough to guarantee good measurements and
the Battery Error Prevention System (BEPS) turns the meter off.

Immediately replace the batteries with new ones.

BATTERY REPLACEMENT

The batteries are accessed by opening the battery cover on
the back of the instrument.

Replace the three 1.5V AAA alkaline batteries located in
the battery compartment, observing the indicated polarity.

Replace the battery cover making sure that the gasket is in place.

All Hanna Instruments temperature probes are pre‑calibrated at
the factory and are ready‑to‑use. These interchangeable probes
make it possible to switch from one probe to another within the
family without requiring recalibration.

Note: To clean the meters and the probes, do not use aggressive

detergents. It is recommended to use water.

Recommendations
for Users

Before using these products, make sure
they are entirely suitable for your specific
application and for the environment in
which they are used. Any variation
introduced by the user to the supplied
equipment may degrade the meters’
performance. To avoid electrical shock,
do not use these meters when voltages at
the measurement surface exceed 24 VAC
or 60 VDC. For yours and the meter’s
safety do not use or store the meter in
hazardous environments.

Ensuring proper product and battery disposal
prevents potential negative consequences for
the environment and human health, which
may be caused by inappropriate handling. For
more information, contact your city, your local
household waste disposal service, the place of
purchase or go to www.hannainst.com.
