GENERAL DESCRIPTION

These thermometers are specially designed with a food com­patible cable, and can be used for continuous monitoring of
temperature in food care areas.

Simply attach the meter to outside a fridge or metal
cabinet. This is possible thanks to the two magnets located
on the back of the unit. The probe can then be inserted
inside the cabinet or fridge for continuous temperature
monitoring.

This thermometer is provided with the unique Cal-Check
feature, for a rapid of the meter calibration at any time
through the TEST switch on the meter front.

Two models are available:

• HI 147-00 (Checkfridge C) displays temperature in
Centigrade degrees

• HI 147-01 (Checkfridge F) displays temperature in
Fahrenheit degrees.
