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

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."

— Matthew S. (5/5)

I bought it to track

"I bought it to track the temperature inside my oven and so far I am liking it as long as it is truly accurate. Not sure how I would know if it is. It is saying my brand new Viking is 25 degrees off."

— Peggy H. (5/5)

Works as expected

"So far I've only used one time but very happy I decided to buy. It was a relief not to have to keep taking my food out of the oven to check the temperature. I like my meats medium rare but I was always leaving them in the oven a little too long, this time I had the perfect amount of pinkness. My only wish was that I had more directions on setting up the Dot and how to correctly place probe wires. Maybe a few more pictures on oven placement of the probe wire on the website or YouTube directions."

— Pamela F. (5/5)

Written instructions totally suck. Customer

"Written instructions totally suck. Customer "Support" was lame. Product might be good if I could figure out how to use it. Plus, I was advised to get the model with two probes & I probably only need one."

— Better D. (1/5)

Works great!!

"I like using 2probes on 1 device."

— Zeph P. (5/5)

Works

"Not sure I got the meat probe right. The oven averaging worked well but instructions are not real clear and use is more complicated that seems necessary."

— DEAN R. (4/5)

"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)

Excellent accuracy snd wife loves

"Excellent accuracy snd wife loves the color"

— Steve D. (5/5)

Game changer!

"Love it. I finally feel in control of my oven temperature, which was not accurate to the dial!!!"

— Pamela R. (5/5)

Square Dot review

"Purchased to check oven temperature. Works beautifully. I also am exploring with ways to use the probes in my baking, meat and fish dishes and at the charcoal grill. Now I wonder how I served perfectly cooked food without it. Very pleased with the product. The online marketing is a bit annoying and I wish it would stop."

— Catherine W. (5/5)
