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 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

Calibrated my ovens!

"I have new nice ovens but the temps were off. This gadget is amazing! It gives you a 20 minute average temp after preheating. One oven was hot & the other cold. I was able to calibrate them then run the test again to verify. Next I baked cookies & used the temp probe to verify before putting them in the oven. They came out perfect. Haven't tried the the other features yet."

— Evie D. (5/5)

Great for a higher level of cooking

"The square dot allows to to not only monitor your food cooking in the oven, it also allows you to have a real idea of you actual oven temperature right where your food is positioned in your oven with the air probe. As always a solid product"

— Jeffrey R. (5/5)

No Low Alarms

"The product description states the Square Dot has independent high and low alarms,... but in reality it only has a high alarm, no low alarm. I called customer service and they transferred me to a technician and he agreed there is no low alarms, only a high alarm on the Square Dot. Other than that it works great!"

— Bob F. (3/5)

Difficult to position

"How do I hang/secure the temperature probe to read the temperature inside my oven, my rack shelves wires are wider than the device stabilizer,any suggestions,this isn’t working for the purpose I intended when I purchases the device. Specifically bought this to know if my oven is heating to a desired temperature."

— Colleen Q. (2/5)

Best Steak I Ever Cooked

"I used the Square Dot to cook two steaks on the grill and they both came off perfect. I always left it up to a simple timer and guess work. Using the dot was night and day. Perfect medium rare on both steaks, which needed slightly different times. Highly recommend."

— Andrew L. (5/5)

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."

— Craig W. (4/5)

Not sure

"Used once, read 160F but chicken was not done. Not sure can say it works or not."

— Lynne P. (4/5)

Huge disappointment

"Used it 3 times. 3 times the meat was not cooked properly. Twice overdone, once under. I've been bbqing for years and years without a thermometer. I don't know what I was thinking about buying this product. I guess I like just throwing money away."

— Mike B. (1/5)

"Solid construction"

— Dakota (5/5)

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)
