Fridge thermometers monitor the current temperature of the fridge, ensuring that food is stored at a safe to eat temperature until served. If the refrigerator is too warm, food incurs bacterial growth and spoils; whereas, if the refrigerator is too cold, electricity is wasted. Generally speaking, homeowners should aim to keep their refrigerator between 2 and 3 degrees Celsius.
Analogue vs. Digital Thermometers
Analogue, or dial, thermometers display the temperature on a dial. Conversely, digital fridge thermometers have electronic liquid crystal display (LCD) screens, making them easier to read. The LCD screen shows the temperature in either Fahrenheit or Celsius degrees. These digital temperature thermometers offer increased accuracy and come in a stylish and compact form. Most modern fridge thermometers have a digital display. When choosing a digital LCD thermometer, remember to change the thermometer battery periodically to prevent power-related issues.
Many fridge thermometers store readings over time. This grants homeowners the ability to review the range of temperatures inside the refrigerator during a specific time period, which helps point out any malfunctioning. Some also feature an alarm that sounds when the fridge rises above or drops below a specific temperature or temperature range. These food thermometers also generally provide a weekly temperature average. Moreover, those who live in an area susceptible to power outages can consider a wireless fridge thermometer, as this allows them to check if the refrigerated food is still safe for consumption without having to open it and let out cold air. These units come equipped with a temperature remote sensor, that when placed in the fridge, sends the temperature reading to wireless LCD screen. For increased versatility, look for wireless fridge freezer thermometers that come with two sensors for the freezer and fridge.
Some refrigerator thermometers are designed for on-shelf placement, while other models are meant to be secured to the interior fridge wall. As for the latter, look for ones that feature a suction cup; this design firmly secures the thermometer to the wall of the refrigerator. Still, other fridge thermometer models feature Velcro that holds the unit in place. Generally speaking, the best place to mount the thermometer is where you can easily read it. The middle shelf or back wall typically offers the most accurate temperature; avoid placing the fridge thermometer near or on the door. You must make sure that the thermometer is compatible with your brand of fridge, whether it be Miele or Samsung.
