Average Mode sets Square DOT apart from other alarm thermometers. Most ovens and pellet smokers fluctuate around their set temperature — often swinging 20–30°F above and below the target. Instead of reacting to every spike when you open the lid or when the heat cycles, Square DOT displays a rolling 15-minute average of your cooking environment. The result is steadier adjustments, more consistent heat, and better outcomes — especially for breads, roasts, and longer cooks where temperature stability matters.

Square DOT is a two-channel alarm thermometer built to give you a clear picture of what’s happening during longer cooks. Monitor your food and your oven, grill, or smoker at the same time — or track two proteins — with independent high and low alarms that notify you when attention is needed. Insert the probes, set your limits, and let Square DOT handle the monitoring while you focus on the rest of the meal. Commercial-grade Pro-Series® probes and a large backlit display deliver reliable data at a glance.

  • Dial In Your Oven Temperature: Most ovens and smokers cycle 20–30°F above and below the set temp. Average Mode shows a rolling 15-minute average so you can adjust for normal heat swings instead of reacting to every spike.
  • Monitor Two Temperatures at Once: Track food and oven temps simultaneously — or keep tabs on two dishes — for better timing and consistency.
  • Set Precise Temperature Limits: Independent high alarms help you catch doneness, stalls, or overheating before they affect results.
  • Read Everything at a Glance: Large, easy-to-read digits show current temperatures, alarm points, and averages on a backlit screen.
  • Built for High-Heat Cooking: Includes Pro-Series® probes rated to 700°F for ovens, grills, smokers, and fryers.
  • Hear It from Across the Kitchen: A 70 dB alarm cuts through everyday noise so you don’t miss key moments.
  • Ready for Kitchen Chaos: IP66 splash-resistant housing protects against spills, splashes, and steam.
  • Stays Visible Where You Need It: Magnetic back and fold-out stand keep Square DOT secure and easy to see.
  • Runs for the Long Haul: Up to 5,000 hours of battery life on two AAA batteries.
  • Verified Precision: Each unit is accurate within ±1.8°F and ships with a NIST-traceable calibration certificate.

Reviews

The Square DOT itself is

"The Square DOT itself is really nice and works well. I use it to monitor my oven temperature when I’m baking things. The device that holds the air temp probe is a different story- it’s way too small to work with my oven racks. I had to fabricate a gadget to hold the probe. Oh well, nothing is perfect."

Probe Mix-Up

"I ordered a 2nd probe for meet do my husband could keep up with my meet and his. I eat smaller and often thinner cuts. We used the wrong probes and the meet got way over cooked before reaching medium rare temperatures. $48 worth of steak was ruined. We will read more on this or call customer service to see how to do better."

Pamela B. (5/5)

For My Oven!

"I bought the Square Dot because I was having temperature issues with my oven and needed a really accurate thermometer to go inside the oven. Works SO well!!!"

Vivian L. (5/5)

It’s the only oven thermometer that works for me

"I just need a dual probe thermometer to take the ambient temp as well as food temp with an alarm that I can shut off. This fills that need."

Jane C. (5/5)

I need practice.

"I’m sure the Dot is a great thermometer it’s me that needs to learn where to place the probe in boneless chicken thighs."

Stephen L. (4/5)

Very nice! The unit and

"Very nice! The unit and included probes are accurate! It’s so nice to know the actual temp in the oven/grill and of the food being cooked."

Kenneth R. (5/5)

"This is the thermapen for the oven. Reliable air and cook temps, without having to open the door to check. If you care about precision, this is a good supplement for baking, roasting, reverse sear, anything oven."

Elijah (5/5)

Square Dot is Great

"The thermometer is easy to use and I was able to calibrate my oven with it"

David Z. (5/5)

No Instructions on proper usage

"I did not get any directions with my Square Dot unit. Once I removed the plastic strip that was protecting the batteries it turned on and started blinking that the probe(s) was not attached. It has been blinking for 2 days and I have not found a way to turn it off. It would also be nice to find out the proper way to use the attachment for the grill or pot that came with it. The unit was recommended, but the information provided with it definitely needs help."

Mommajor (2/5)

Best Investment

"Love it. Best Investment for the oven or BBQ. I did a brisket this past weekend and with the Square I was able to watch and hear the right temperature being reached. I should have bought a thermometer like this years ago."
