  • Ease of use.

CHOICE tests are different. We buy the products we test — no freebies from manufacturers. Companies can't buy ads on our site and our work is funded by people like you.

Please note: this information was current as of October 2007 but is still a useful guide to today's market. 

Why a thermometer?

To keep food safe to eat, it must be chilled at below 5°C or frozen at or below –18°C. Any warmer and you have the potential for harmful bacteria growth.

Measuring the temperature in your fridge allows you to accurately set the controls so as to get the best quality and longest storage times for your food.

Thermometers for fridges may even help reduce your household’s CO2 emissions. We calculated that a current-model freezer, running just four degrees colder than is needed (–22°C instead of –18°C, say) would produce around an extra 138kg of CO2 emissions per year.
