A lot What goes into making a great meal, whether it’s a steak on Tuesday or Thanksgiving, is your ability to control the temperature. No amount of chopped parsley or sprinkled fennel fronds can make meat overcooked. (Although mayonnaise can rescue a leftover turkey sandwich.) And that’s just the unpleasantness of chewing on tough supermarket steaks, because accidentally putting in raw chicken is more serious. However, only one in four adults say they use a thermometer frequently when cooking proteins.
Wireless no-rinse probes intended for outdoor cooking, which have been out of service for years, have issues with connectivity. These probes work… until you close the oven door on a bird, the lid of a pellet smoker grilling a brisket, or step away from the ribeye on your grill. That’s when the faulty behavior starts: dropped connections, repair requests, timeouts, or temperatures that didn’t seem to change. Some maintain a steady connection, but can be difficult to work with, especially for a hobby cook who might put them to work a couple of weekends a month. What good is a wireless probe without the confidence to step away from the stove or smoker and take a nap inside while the collagen breaks down in your pork butt?
I spent a few days testing these probes: using the apps, checking responsiveness, and checking connectivity in my kitchen and backyard. I then subjected them to the Ironman test: putting the probes in a Staub Cast iron Dutch oven placed on a Yoder pellet smoker (8/10, WIRED recommends), one of the most robust stoves on the market, and checking to see if they stayed connected. I also grilled steaks over hot charcoal to see if the high heat bothered the probes. Fans of Kamado cookers don’t worry: While ceramic grills have thicker walls than any metal smoker, steel is generally harder to penetrate for these frequencies, so these probes should work with your Big green egg also.

Can these probes be used when grilling?
Yes. The probes can withstand temperatures of 800 to 1000 degrees Fahrenheit before risking damage to the sensors, which is typically more than the power generated by charcoal briquettes, which run hotter than a traditional gas grill. There are some scenarios, like caveman cookingwhere the protein sits directly on the coals, or using an infrared gas grill, that could be risky for the probes because it can expose them to temperatures over 1000 degrees, but for most everyday cooking, these probes will handle any whatever you throw at them. them.
What is the temperature range that these probes track?
While the probes can withstand up to 1,000 degrees Fahrenheit, don’t expect to see readings from a steak that has reached 400 degrees. Sensors buried in food typically track temperatures from 14 to 212 degrees Fahrenheit. You can use probes to confirm that the freezer is humming at 0 degrees Fahrenheit, the refrigerator is chilling at 40, and the birds are hitting 165, which is about the highest internal temperature of the proteins you’re eating. If the sensors on the main part of the probe heat up above 212 degrees Fahrenheit, you’ll get an alert to cool things down. For example, you cannot place the probe in a vat of oil and use it as a frying thermometer. A notification could mean that part of the probe is touching a metal grate or is exposed to ambient temperatures above 212 degrees, such as in a deep fryer.
The outlier is the environmental sensor at the rear end of the probe. This specific sensor is located outside the food, so it is designed to accept more heat than the main probe because it receives more convection, conduction, and infrared energy. Those who bake, roast, and roast at lower temperatures for longer periods tend to worry more about room temperature than those who grill hot and fast.
Can the probes be calibrated?
Not precisely. One laboratory has verified the accuracy of many of these probes within the plus or minus range they provide, which is typically around 1 degree. If you suspect the probe’s accuracy is off, a quick way to check is to dip the tip into boiling water, which should read 212 degrees Fahrenheit. (at sea level) and then in a ice water bathwhich should read 32 degrees Fahrenheit (if you avoid touching a cube). If the probe reading is outside the indicated range, contact the manufacturer.
If the probes have multiple sensors, what temperature is displayed on your smartphone?
The lowest temperature inside your food. Once you set your target temperature, the probe tells you what the coldest reading is within your dinner. While the app displays a number, from a bird’s eye view, most allow you to dial in and view the temperature of individual sensors inside the probe, which can be useful for larger cuts, like brisket or rib roast. The temperature read by the ambient sensor is not taken into account on the screen displayed by the thermometer.
Do all probes track room temperature?
Yes, but the accuracy of that specific reading varies and not all probes verify it the same way. Most probes include an environmental sensor on the rear end, designed to withstand the most heat since the air, frying oil, or, in the case of sous vide, water, around the food is hotter. than the center of whatever you are cooking. ThermoWorks is the only system that tracks room temperature with a wired probe that connects to a base station.
The reasoning is the second law of thermodynamics: inserting a conductive metal probe into cold food moves the temperature away from the built-in ambient sensor as hot turns to cold. Beyond that, in a hot oven, that large block of thermal mass (cold food) is covered by a blanket of cooler temperature, caused by water evaporating from the surface. Unfortunately, the location of the ambient sensor inside the probe, which protrudes about an inch out of the food, is in that misleading area that indicates a temperature colder than the actual ambient temperature. To solve this, ThermoWorks uses a wired probe held by a spring clip that is designed to rest on the oven rack or the grate of a grill or smoker close to the food, but far enough away that it doesn’t pick up the cooling. by evaporation. Tracking room temperature is less important if you’re cooking a steak or pork chop, but it’s something backyard grillers pay close attention to, because the name of the game is low, steady heat that’s maintained for hours.
How do you insert a probe into food?
Each probe axis has a minimum insertion line marked. In practice, approximately ¾ of the length of the thermometer is buried in the food so that the main sensors are protected from heat. Try to rest the tip of the probe in the center of the fattiest part of the food, avoiding bones or pockets of cartilage or fat, which can alter temperatures. With more sensors, electronics, and a battery built into the probe, placement can be complicated compared to wired probes, which only take readings from the tip. You may be able to insert a wired probe into a thick fillet across the top of the cut or at an angle, but that won’t work well with a wireless probe, which is typically heavier, more flexible, and requires all of the sensors in the shaft are submerged. meat to avoid a high heat alert. Wireless probes don’t work well in all situations, such as thin chicken cutlets, narrow sausages, or very delicate fish; These probes have a wider diameter than the wired versions. It is good practice to position the probe so that the end, which often houses the environmental sensor, does not touch the grille or any other metal, which can give a false reading.
My process for setting up a probe begins by syncing it with the app on my phone to see that the thermometer registers the room temperature. I then set the target temperature in the app and check again for low battery warnings. Finally, I insert the probe into the thickest part of the food, making sure the temperature changes, which it should since the protein is usually around 40 degrees Fahrenheit outside the refrigerator. If you are ever in doubt about the probe’s performance, you can always grab or pinch the probe with clean hands and wait for the temperature to rise a few degrees upon application.
Will you need an app?
In most cases, checking the smartphone app helps and may be necessary. Not all probes have a base station with a display, which means you’ll need an app to set target temperatures and receive notifications. Some probes offer Apple Watch apps that handle the basics of communicating the current temperature.
Is this the only thermometer you will need?
No. Wireless probe thermometers are a good option for indoor grilling or searing, or outdoor grilling or smoking, and while they are responsive, they are not a substitute for an instant-read thermometer that can show the temperature inside the food. in a couple of seconds. . Instant-read thermometers are also thinner, making it easier for them to temper things like chicken tenders and wings.
