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.

Square DOT features a fold-out stand and a magnetic back for surface mounting. Includes a Pro-Series® penetration probe, and a Pro-Series air probe with Grate Clip.

  • 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.

Overall rating: 4.5867767 / 5 from 484 reviews.

Reviews

Four stars, not five, and I'm being generous.

"The clip that holds the thermometer on the grate doesn't work very well in my oven. I have to bend it. It's always flashing some message. Does it matter which hole the oven temperature probe is plugged into? And if I don't need the food probe, the missing-probe message blinks nonstop, which is annoying. The up-and-down temperature arrows are very clunky. I have to press them several times just to move one degree. The directions on the instruction sheet should be more complete. And it needs some kind of foldable, attached stand. It only lies down on its back."

— Douglas N. (4/5)

love the dual probes to measure the food and the oven

"I bought this so test the operating temp of my ovens. Both were off, one by 15 degrees too warm the other by 5 degrees too cold. I measured boiling water to check the accuracy of the device, and based on that, decided to trust its accuracy in the oven. Tonight I will be trusting it to tell me when a fancy piece of steak is done cooking!"

— Jonathan P. (5/5)

Perfect for monitoring oven temps

"We just moved into a new place with an oven that does not have a temperature read out, temp ready alert, or many controls at all. It works well, but can be hard to gauge the temp. the square dot solved that instantly. it worked perfectly out of the box. one thermometer is always in the oven and one can used as a probe. The probe with the alarm setting nailed the temp exactly on the first try. Otherwise, we would have overcooked it. The average temp feature and alarms are extremely useful and work well. no more guessing!"

— Sam (5/5)

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)

How to get average oven temp

"I can’t figure out how to record the average oven temperature. I attach the first probe to the oven rack to tell me the current oven temperature. Does the second probe just need to lay on the rack in the oven to provide the average temp."

— Sherry M. (3/5)

Verified Oven Temp

"We thought that our Thermador oven had issues with heating accuracy, but the SquareDOT was able to indicate there was no issue."

— CRAIG L. (5/5)

I am a home cook

"I am a home cook and bought this to watch the temperature of my oven. It has nice features with the probe for food which I know I will like. I called your customer service to ask a question and had a very good experience. Your products are very good quality."

— JO G. (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)

Square DOT first use

"Very useful in analog ovens, where temprature is difficult to adjust. Oven has peaks and valley mode so you have to monitor. Easier to use than an in oven temprature gauge."

— Francisco G. (5/5)

You Need This

"I was having problems with a new grill, temps everywhere, lower than displayed, higher than displayed. I needed to know what the temp was. This confirmed all of my suspicions. Now I know what the temperature really is."

— Maxie J. (5/5)

Q&A

How do I change the battery? Nothing in the literature says how.
On the back side of your Square DOT you will see a battery door secured with a phillips screw. Loosen that screw and lift the battery cover to access the battery compartment. There you will find 2 AAA batteries. Replace the batteries then reinstall the battery cover and you will be ready to go!
Can you use the Square Dot with 1 or the other probe only? So if I wanted to only monitor oven temp and not use the food probe? Or Vice versa? Would you just not connect the one you didn't want to use or just not insert/set alarm?
Yes, you can use your probes in any configuration (including only one at a time). However, Average Mode is only available on channel two so be sure to use the lower port if you want to take advantage of that feature.
what is included and why do parts come seperate?
SquareDOT® includes the main dual-channel display unit, a 2-inch Pro-Series® Air Probe with a grate clip (for monitoring oven or smoker air temperatures), a Pro-Series® High Temp Straight Penetration Probe, AAA battery, and a Quick Start Guide. Separate probes make it easy to replace an individual probe if one wears out, saving you from replacing the whole unit. They also allow you to mix and match different Pro-Series® probe styles depending on what you are cooking!
How long are the probe cords for the square dot?
The Pro-Series probe cables are 48 inches long.
I have the regular round DOT. Can you explain how the Square DOT differs, what the numbers exactly represent & how accurate those numbers are. Thank you.
Square DOT expands on the original DOT by giving you two channels to track two temperatures simultaneously, like meat and air temp! The screen displays your live probe readings, set high-alarm targets, and a rolling 15-minute average on Channel 2 that smooths out normal oven cycling so you can dial in true heat. It delivers rock-solid accuracy within ±1.8°F in normal cooking ranges (-4°F to 248°F) and comes verified with an individual NIST-traceable calibration certificate!
