The 10 Best Refrigerator Thermometers

This wiki has been updated 18 times since it was first published in August of 2019. If the temperature in your refrigerator is higher than 40 degrees Fahrenheit, or 4 degrees Celsius, your food is at risk from harmful bacteria. Unfortunately, you can’t tell by feel exactly how cold the interior is, which is why you need one of these handy thermometers. And even if your fridge has one built in, a separate, freestanding unit can help you check for accuracy from time to time. When users buy our independently chosen editorial selections, we may earn commissions to help fund the Wiki.

Editor's Notes

August 23, 2019:

Any of the refrigerator thermometers on this list will help you keep your food out of the danger zone — and most are fine for chest or upright freezers, too. For the tech-savvy, we like the SensorPush Wireless. It has Bluetooth capabilities built in, but if you need information over a longer range, you can add the SensorPush G1 WiFi Gateway. Of course, this bumps up the overall price, but it works with multiple sensors and can monitor the temperature and humidity all over your home. There’s also the Temp Stick Wireless Remote, which has integrated Wi-Fi connectivity. On one hand, this means there’s nothing else to purchase, but on the other, it means that the initial investment is quite a bit higher. For those who want a simple analog model, the Rubbermaid Commercial Instant Read or Wrenwane Digital are both handy choices. The former is NSF certified, too.

You can monitor and adjust the temperature from anywhere with your smartphone, as well as take a peek at the interior with its three built-in cameras.

2di TV2 Master Thermometer For medical and laboratory settings where accurate temperatures are an absolute must, there’s the 2di TV2 Master Thermometer. It offers documentation and monitoring you can count on, even in a power failure, thanks to a 100-hour backup battery.
