All Hanna Instruments meters are warranted for two years against defects in work-
manship and materials when used for their intended purpose and maintained according
to instructions. This warranty is limited to repair or replacement free of charge.
Damages due to accident, misuse, tampering or lack of prescribed maintenance are
not covered. If service is required, contact the dealer from whom you purchased the
instrument. If under warranty, report the model number, date of purchase, serial
number and the nature of the failure. If the repair is not covered by the warranty, you

instrument, make sure it is properly packaged for complete protection.
Recommendations for Users
Before using this product, make sure that it is entirely suitable for the environment in
which it is used. Operation of this instrument in residential areas could cause inter-
ference to radio and TV equipment. Any variation introduced by the user to the
supplied equipment may degrade the instrument's EMC performance. To avoid elec-
trical shocks, do not use this instrument when voltage at the measurement surface
exceeds 24 Vac or 60 Vdc. To avoid damage or burns, do not perform any measure-
ment in microwave ovens.

The HI145 thermometer is the ideal solution for
temperature monitoring of semi-solids, such as fro-
zen foods, as well as applications, such as in food
preparation and during cooking.
The HI 145 series is equipped with the exclusive
Cal-Check®feature. When teh instrument is turned
on, it performs a self check of its calibration status
and displyas it on the LCD.
HI145-00 (°C) and HI145-01 (°F) are equipped with
a 125 mm (5”) long AISI 316 stainless steel probe.
It has a conic sharp tip which provides fast re-
sponse and improved accuracy over the entire range.
HI145-20 (°C) and HI145-30 (°F) are supplied with
a 300mm (12”) long stainless steel probe and are
ideal for monitoring hot liquids in cooking applica-
tions, such as deep frying and soup preparation.
OPERATION
• Turn the HI145 on. The “CAL” message on the
LCD indicates that the instrument is performing
an automatic calibration check. If the test is suc-
cessful, the LCD will display “-0-”. If the calibra-
tion check fails and the meter requires re-calibra-
tion, the LCD will display “ERR”.
After performing the calibration check, the instru-
ment will automatically enter the normal mea-
surement mode.
• Insert the probe into the sample to be measured.
Thanks to the special probe shape, the insertion
even into semi-solid samples is very easy.
• Wait for a few seconds for the display to stabilize.
• To freeze the display, press the HOLD button. A
blinking M appears on the right side of the LCD to
indicate that reading has been memorized. Press
either button to return to the normal mode.
• After use, switch the instrument off, or the meter
automatically turns off after 8 minutes of non-use.
•Variations in readings or fading display can
indicate a low battery level.
FACTORY CALIBRATION
If the meter needs re-calibration, contact your deal-
er or the nearest Hanna service center.
It is recommended to recalibrate the thermometer
once a year.
BATTERY REPLACEMENT
When the HI145 cannot be switched
on or the display fades, unscrew the
two screws to access the battery com-
partment and replace the 1.5V AAA
battery, while paying attention to its
polarity.
Battery should only be replaced in a
safe area using a 1.5V AAA alkaline
battery.
PROTECTIVE CAP
The thermometer is supplied with a
protective cap, which can also be
used to hold the thermometer on the
side of a vessel.
