The HI145 thermometer is the ideal solution for temperature monitoring of semi-solids, such as frozen 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.

HI 145-00 (°C) and HI 145-01 (°F) are equipped with a 125 mm (5”) long AISI 316 stainless steel probe. It has a conic sharp tip which provides fast response and improved accuracy over the entire range.

HI145-20 (°C) and HI 145-30 (°F) are supplied with a 300mm (12”) long stainless steel probe and are ideal for monitoring hot liquids in cooking applications, 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 successful, the LCD will display “-0-”. If the calibration check fails and the meter requires re-calibration, the LCD will display “ERR”.

After performing the calibration check, the instrument will automatically enter the normal measurement 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 dealer or the nearest Hanna service center.

It is recommended to recalibrate the thermometer once a year.

BATTERY REPLACEMENT

When the HI 145 cannot be switched on or the display fades, unscrew the two screws to access the battery compartment 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.
