It's important to keep food at the optimal temperature -- usually 40 degrees Fahrenheit or below -- to ensure it stays fresh and bacteria-free. While many refrigerators have built-in thermometers, some don't. If you don't have a thermometer in your fridge or freezer, or if you just want to keep an eye on certain areas of your appliance (like the crisper or meat drawer), a separate thermometer can help. When looking for a refrigerator temperature gauge, consider its connection (magnetic, hanging, clip-on, or vertical), display type, and whether it is waterproof.
We like this refrigerator thermometer to cover all the bottom because it has two channels and two probes and it can be used in the refrigerator and freezer at the same time. Simply place one probe in the freezer and the other in the refrigerator. You can also set high and low temperature limits, so you don't have to take readings manually all the time.
The thermometer also includes a handy fold-out stand and magnetic back clamps, so it can be placed wherever you put it. Plus, it has a very easy to read LCD monitor to make sure you get the temperature readings just right.
The other, magnetic refrigerator thermometers have many advantages: There's no worry that your thermometer will tip over, making it harder to read. Plus, if you can stick it to the wall of your fridge, you save valuable space. We love this round device that has precious magnets, but it also comes with a clip and a stand if you want to collect it the old-fashioned way.
