Best Refrigerator Thermometers of 2025

"I recently got these thermometers for my new refrigerator and placed one in the fridge and one in the freezer. They confirmed that my LG settings of 37 and 0 degrees were accurate. After just two hours, the readings matched perfectly with the digital display. Even though they aren't digital, the dials are easy to read, and I feel confident in their accuracy."

"These thermometers are perfect for my RV fridge and freezer. They're accurate and match my fridge's built-in thermometer. The large dial and red indicator make it easy to spot the temperature at a glance. Plus, they fit nicely in my RV and have a hook for easy hanging. No issues so far!"

"I purchased a pair of these thermometers to monitor my deep freezer. They work wonderfully! I feel it's a great investment considering what it could save me in terms of food loss and health if the freezer temperature rises. Highly recommend!"

"I found this thermometer to be a gamechanger. I had no idea my oven's temperature dial was slightly off, and it has eliminated the guesswork in my baking. We're able to produce better food more reliably now, and I believe it's definitely worth it!"

"I purchased this thermometer to adjust my new oven's temperature. The large numbers make it easy to read, and it's been quite accurate. I'm satisfied with the purchase and consider it a great value for the price!"

"I have three chest freezers, and I was worried about losing their contents if the GFCI tripped. After seeing this system recommended, I decided to try it.

"I find this thermometer absolutely essential. It's surprising how many people lack one in their fridge. This tool helps verify the exact temperature, which is crucial for food safety. For under $20, it's a small investment with great benefits. I now monitor my fridge's temperature closely, ensuring it's always at the right levels to prevent bacterial growth."

"I've purchased this thermometer three times, and I've never faced any issues. It’s extremely accurate, easy to read, and works quickly. I highly recommend it for anyone looking to maintain proper temperatures in their fridge and freezer."

It’s definitely a quality NSF approved thermometer and worth the investment."

"Initially, I faced the same issue as others regarding the suction cups not sticking well enough. To make them work, I wet the underside of each cup and pressed them firmly into place before freezing them. A few hours later, I reattached the thermometer, and it held up well even with the added weight of my keys, showing that the suction cups can work if applied correctly."

"This thermometer has been a bit of a disappointment. It's quite hard to read; you have to tilt it just right to see the mercury, and they fog up once inside the fridge. I attempted to use the suction cups, but they frequently pop off, making it tricky to mount them on glass shelves. I wish I could return them."

"I've tried various dial-style thermometers, but I find this one to be far more consistent in its readings. It's definitely easier to read than others I've used, and the price is fantastic."

"I purchased one of these thermometers back in 2020, and after keeping it in my freezer for nearly four years, I finally replaced the battery in 2024. Despite the display dimming, it maintained its accuracy. It uses a CR2032 battery. It’s easy to use, and the temperatures reported align well with my other thermometers. The magnet holds well on flat surfaces, and the kickstand is handy for propping it up. I’ve dropped it multiple times, and even after being frozen for years, it still works great. I’m getting another one for my second freezer!"

"I bought these to replace a previous thermometer that had issues in cold temperatures. They are reasonably priced and pretty accurate. The compact size is perfect for hanging in my extra freezer, which only has a knob to indicate coldness. Now I can ensure it’s set to the proper temperature."
