The thermometer is waterproof and is rated
IP65.

The meter is specifically designed for measuring
the temperature in many chemical processes that take
place during the beer production including mashing, wort
separation, fermentation and finally packaging, distribution
and aging.
Both air temperature and product internal temperature can
be measured with this thermometer.
The dedicated probe FC762N2 shaft is designed for continuous
contact with foodstuffs in accordance with Regulation (EC)
1935/2004.
Temperature plays a central function in brewing operations.
Spot checking temperature throughout the process ensures
daily work routines are carried out at the correct temperature,
and equipment is operating efficiently. Temperature
measurements are made at the hot water tank, the mash
tank, the boil kettle, fermenter, bright beer tank and final
storage area. Temperature checks provide peace of mind
the operation is running smoothly and the batch will be
uncompromised.
Hanna Instruments manufactures the HI935012 Beer
thermometer to meet the tough environment encountered
in the beer sector. Standard features include a ruggedized
professionally designed waterproof case and stainless steel
probe for measurements. The meter provides good accuracy
and includes features such as CAL Check, user calibration at

0.0 °C (32 °F), low battery detection, auto‑off capability,
and has a long battery life.
The model HI935012 thermistor style thermometer
measures temperatures from ‑20.0 to 120.0 °C (‑4.0 to

248.0 °F). It comes with a stainless steel replaceable style
probe (FC762N2).

Each meter is supplied with batteries. Remove the battery
cover, unwrap the supplied batteries and install them
while paying attention to their polarity (see the “Battery
replacement” section for more details).

START UP

Connect the temperature probe to the meter.
To switch the meter ON, press the ON/OFF

button on the front of the meter. If it does not

OPERATIONAL GUIDE

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.

Note: The full display can be frozen by keeping the
ON/OFF button pressed.

Battery Life

Place the stainless steel tip of FC762N2 thermistor probe
into media you wish to measure. The probe should reach
the final temperature in a few seconds. Measurements in
air may take longer to equilibrate.

8

CALIBRATION CHECK

The meter is 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” (“32.0 °F“), ±0.3 °C (±0.5 °F) for a
few seconds.

CALIBRATION

The meter can be calibrated in 0 °C (32 °F) by using an
ice bath.

• Prepare an ice bath with approximately equal volumes
of distilled water and chopped ice made from distilled
water.

• Immerse the temperature probe in the center of the ice
bath, taking care not to touch the ice with the probe tip.

• Ensure that the meter is measuring a temperature within
±1.5 °C (±2.7 °F).

OPERATIONAL GUIDE

• To enter the Calibration mode, press and hold the ON/OFF
button, when the meter is in measurement mode. Meter
will display ”OFF” then “CAL“. Release the button and
the meter will then enter Calibration Mode.

• The CAL tag turns on to indicate that the Calibration
mode has been entered.

9

Note: If the measurement is outside the ±1.5 °C
(±2.7 °F) window, the meter enters Calibration
mode with value blinking. Contact you local Hanna
Instruments office for a check if the blinking persists.

• When the meter reaches the stability condition, which
is detected when the measurement remains within
±0.2 °C (±0.4 °F) for 5 seconds, the calibration is
accepted and the reading becomes 0 °C (32 °F).

• The meter then automatically returns to normal mode

OPERATIONAL GUIDE

displaying “Stor“.

Note: To exit the Calibration mode at any time, press
the ON/OFF button. “ESC“ is displayed and the meter
returns to measurement mode.

10

To erase a previous calibration, from Calibration mode,
press and hold ON/OFF button for a few seconds until
“CLr“ is displayed.

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.

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

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

11

WARNING MESSAGES

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.

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.

OPERATIONAL GUIDE

CALIBRATION CHECK ERROR MESSAGE

If during CALIBRATION CHECK the meter displays more
than ±0.3 °C (±0.5 °F), then an “Err” message is
displayed.

Contact your local Hanna Instruments Office for recalibration.

12

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.

SET button

• 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.

METER SETUP

• 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.

13

METER SETUP

8 minutes

Disabled

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

60 minutes

BATTERY REPLACEMENT

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

BATTERY REPLACEMENT

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

14

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

BATTERY REPLACEMENT

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

15

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 meter and the probe, do not
use aggressive detergents. It is recommended to
use water.
