GENERAL DESCRIPTION
Temperature plays a very important role in the food industry, and it
also has to be checked in the warehouses, loading docks and in
transportation vehicles.
You can choose the Hanna food-thermometer which best meets your
needs, among several models:
HI 9041 and HI 9061 are simple-to-operate instruments that provide
excellent accuracy and can operate with a wide range of interchangeable probes (designed for air, liquid or penetration; see page 15)
without requiring recalibration. HI 9041 and HI 9061 are available
in either °C or °F models.
HI 93501, HI 93502, HI 93503 and HI 935007 are professional,
rugged and waterproof thermometers, designed to be used on a daily
basis in industrial kitchens and catering.
Standard features include low battery detection, auto-off capability
and long battery life.
Moreover, HI 93501, HI 93502 and HI 93503 are provided with the
exclusive Cal-Check feature for checking the meter calibration status at
any time. They use interchangeable probes (see pages 14-15).
HI 935007 is a K-thermocouple thermometer. It offers a wide
temperature range, automatic change of resolution from 0.1° to 1°,
and user-selectable measurement unit (°C or °F).

OPERATIONAL GUIDE
Each meter is supplied complete with batteries. Remove the back
cover, unwrap the supplied batteries and install them while paying
attention to their polarity (see also the "Battery replacement" section
for more details).
Note: HI 93501, HI 93502, HI 93503 and HI 935007 come with
batteries already installed.
TAKING MEASUREMENTS
Connect a suitable temperature probe to the meter (see pages 14-15 for
a complete list of Hanna probes).
Note: HI 935007 has 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; then it enters normal measurement
mode.
Note: The full display can be frozen by keeping the ON/OFF button
pressed.
If a temperature probe is plugged in, the meter displays the measured
temperature.
If no temperature probe is plugged in or the reading is over-range, the
display shows blinking dashes. If the reading is slightly beyond the
measuring range, the meter flashes the closest full-scale value.
To switch the meter OFF, press the ON/OFF key.
AUTO SHUT-OFF (not for HI 9041 and HI9061)
To save battery life, HI 93501, HI 93502, HI 93503 and HI 935007
models are provided with an auto-off feature, which switches the
instrument off after a certain period of nonuse.
The auto-off delay time (default value is 60 minutes) can be changed
by the user (8 minutes, 60 minutes, or disabled) with an internal
button located in the battery compartment (see figure on page 12).
Unscrew the 4 screws on the back of the meter and select the desired
auto-off time period by pressing the button and viewing the value on
the LCD.
10
Reattach the back making sure that the gasket is in place and
tighten the 4 screws to ensure a watertight seal.
CALIBRATION CHECK
(for HI 93501, HI 93502 and HI 93503)
The HI 93501, HI 93502 and HI 93503 models are provided with
the Cal-Check feature, which allows the user to check the instrument
calibration status at any time.
Press and hold the CAL CHECK button.
If the meter is calibrated, the display will
stabilize and show “0.0°C” (±0.3°C) in a
few seconds.
To return to measurement mode, release the button.
Contact your dealer or your nearest Hanna Service Center for recali-
bration, if necessary.
°C/°F SELECTION (HI935007 ONLY)
• The meter displays the measured temperature, automatically
switching to the resolution suitable for the temperature range; i.e.
0.1° up to 199.9°C (399.9°F), or 1° above.
• The user can select the measurement
unit by pressing the °C/°F button.
BATTERY REPLACEMENT
When the remaining battery life is less than
10% the battery tag blinks on the display
to warn the user.
If the battery level is low enough to cause erroneous readings, the
Battery Error Prevention System (BEPS) turns the meter off.
Immediately replace the batteries with new ones.
Battery replacement must only take place in a non-hazardous area
11
using the battery type specified in this instruction manual.
• HI 9041 and HI 9061: remove the battery cover and replace the
batteries (1x9V for HI 9041 or 4x1.5V AA for HI 9061) with new
ones, while paying attention to their polarity. Reattach the battery
cover.
• HI 93501, HI 93502, HI 93503 and HI 935007: the batteries
are accessed by separating the front and the back halves of the
meter. Unscrew the 4 screws on the back of the meter and carefully
replace the three 1.5V AA alkaline batteries located in the battery
compartment, while paying attention to their polarity. Reattach the
back making sure that the gasket is in place and tighten the 4
screws to ensure a watertight seal.

FACTORY RECALIBRATION
All Hanna thermometers have been accurately pre-calibrated at the
factory. It is generally recommended to have all thermometers
recalibrated at least once a year. For an accurate recalibration,
contact your nearest Hanna Customer Service Center.
Hanna Accuracy Test Plugs provide a quick and easy way to check
the meter's accuracy by simply connecting these Test Plugs to the
probe connector of the meter. If the reading differs by more than
±0.4°C (±0.8°F) from the Test Plug value, the meter is due for
recalibration.
Choose the right Test Plug to suit your needs:
FOR HI 9041 AND HI 9061
HI 765-18C Calibration key, -18.0°C
HI 765000C Calibration key, 0.0°C
HI 765070C Calibration key, +70.0°C
HI 765-004F Calibration key, –0.4°F
HI 765032F Calibration key, 32.0°F
HI 765158F Calibration key, 158.0°F
Recommendations for Users
Before using these products, make sure that they are entirely suitable for the
environment in which they are used.
Operation of these instruments in residential area could cause unacceptable interferences to radio and TV equipments, requiring the operator to take all necessary
steps to correct interferences.
Any variation introduced by the user to the supplied equipment may degrade the
instruments' EMC performance.
To avoid electrical shock, do not use these instruments when voltages at the measurement surface exceed 24VAC or 60 VDC.
To avoid damages or burns, do not perform any measurement in microwave ovens.
Note: To clean the meters, do not use aggressive detergents. It is
recommended to use water.

TEMPERATURE PROBES
Hanna offers a wide range of probes to meet your needs with air,
liquid, penetration and surface measurements.
All Hanna temperature probes are pre-calibrated at the factory and
ready-to-use. These interchangeable probes make it possible to
switch from one probe to another without requiring recalibration.
Hanna probes are also available in different handle colors to avoid
cross contamination during testing.
