The thing that sets the Combustion Thermometer apart from almost everything else on the market is the way it uses its readings to track the cooking process and predict when your food will be ready. You can set a target temperature, and the thermometer tracks how quickly your food is heating up, along with the ambient temperature. It then uses that data in a built-in algorithm to estimate how much cooking time is left. It’s not perfect for particularly long cooks (it struggled to deal with a brisket stall in our tests), but for shorter- or medium-length cooks, like when we roasted a whole chicken, it proved quite accurate. It can also alert you when enough of your food reaches the USDA’s minimum internal cooking temperatures for food safety.
Unlike the RFX, the Combustion really could be your only cooking thermometer, as it also works as an instant-read, registering readings in our boiling and freezing water tests in about two seconds. It also has a wide temperature range—the entire upper half of the probe can withstand temperatures up to 900°F, making this versatile enough to use when deep frying or in a pizza oven.
Finally, while you can just use the probe with the Combustion app, you can also get a digital display that shows both temperature and predicted finish time for an added layer of visibility.
What we’d leave: The reason we recommend getting the (slightly more expensive) version of the Combustion with the Wi-Fi booster is because we did have signal issues with the standard version. When using it in the backyard I had to stand outside in order to get a reading.

Thermoworks Thermapen One
Pros & Cons
Pros:
- Fast read
- Automatically rotating display and backlight
Cons:
- A little pricey
Specs
- Probe length: 4.25"
- Temperature range: -58.0°F–572.0°F
- Features: Automatic on-off, automatic backlight, rotating display
- Warranty: 5 years
Instant-read thermometers do not come faster or easier to use than the ThermoWorks Thermapen One.
What we love: The two most important features of an instant-read thermometer are its accuracy and its speed, and the Thermapen One excels with both. It took one second to produce an accurate reading in our water boiling test and two seconds in our freezing water test. The focus on speed might seem excessive, but remember, whenever you go to check temperature, you’re opening the oven or grill and the longer it’s open the more the temperature inside will drop.
Besides its quick read capability, the Thermapen has a few other nice features. It turns on automatically when opened, goes to sleep if not used (you can set the sleep function to kick in anywhere between 10 seconds and three minutes), has an LCD display that rotates so you can read the thermometer easily at whatever angle you’re holding it. And while the battery life is not an issue (we used one for over a year without changing the battery), the Thermapen One has an easier to open battery compartment than the original Thermapen and uses a AAA battery instead of two of those annoying to find circular batteries.
What we’d leave: This is the ideal instant-read food thermometer in our opinion. The only downside is price—it retails for over $100. However, it’s frequently on sale for less.
Best budget meat thermometer: Kizen Instant-Read Meat Thermometer
Kizen Instant Read Meat Thermometer
Pros & Cons
Pros:
- Very affordable
- Has backlight
Cons:
- Slower to read than more expensive instant thermometers
Specs
- Probe length: 4.4"
- Temperature range: -58.0°F–572.0°F
- Features: Backlight button, automatic on-off, hold temperature setting
- Warranty: Limited lifetime
What you sacrifice in speed and features when dropping down from the Thermapen you make up for in a price tag of under $15.
What we love: During our tests, the Kizen proved to be a powerful thermometer for the money. It did take four seconds to read during the water boiling test, but it has a number of other nice features that make it user friendly. A button turns on a backlight for use in dark settings, another toggles between Fahrenheit and Celsius. The display automatically turns on when you unfold it and a magnet lets you stick it on to the door of your range or fridge so it’s easy to keep track of.
What we’d leave: It does take four times as long as the Thermapen to provide a reading, but that is the kind of compromise you should expect to make if you’re spending under $20. The sleep function also takes 10 minutes to turn on and isn’t adjustable.
How we tested meat thermometers
To find the best meat thermometers, we put a range of leave-in and instant-read models through hands-on testing both in the kitchen and on a grill and smoker. We evaluated accuracy, response time, ease of use, and additional features to determine which tools were the most reliable, intuitive, and helpful for optimal cooking performance. Here’s how we tested:
Boiling water and ice water tests
To test accuracy, we used each thermometer to measure boiling water heated with an electric kettle equipped with a thermostat and then into a bowl of ice water to see how close they came to hitting 212°F and 32°F.
Response time
We also noted how long it took the thermometers to reach their final reading. While the difference between a one-second and two-second response time isn’t all that relevant, if a thermometer takes too long to register a reading it can be uncomfortable to use over a hot grill or oven.
Ease of use
For instant-read thermometers we used them repeatedly to check the internal temperature of chicken breasts baked in the oven and burgers on the grill to get a sense of how comfortable and easy they were to use in real life.

Consistency and features
For leave-in digital meat thermometers, we used them to monitor doneness when roasting spatchcocked chickens, checking to see how consistent their signal was and utilizing any special features like predicted finish times or ambient temperature sensors.
What makes a good meat thermometer
We only tested digital meat thermometers here. You can use an analog thermometer like this, but it will be slower and more challenging to read. Here are the other things we looked for in our tests.
Accuracy
A thermometer is a measuring device—that’s it. If it can’t give an accurate reading, it’s of no use to anyone.
Speed
This is for any thermometer claiming instant-read capabilities. You should be able to get in and get out of a piece of meat quickly. It can be both uncomfortable to hold your hand over a heat source, and it can mess up the temperature inside your oven or grill if it takes too long.
Number of sensors
Makers of leave-in thermometers have started adding multiple sensors along their probes, which make it easy to see if part of what you’re cooking is getting done too quickly (and probably drying out).
Features
Some thermometers come with alarms, some use predictive algorithms to tell you when your meal will be ready, others connect to Wi-Fi so you can check a long cook if you need to step out of the house.
Other thermometers we tested and liked
These thermometers still performed well across our tests, and we think you’ll be happy if you pick one of them, but they lack some of the features of our top picks.
Wireless thermometers
Typhur Sync Gold
Typhur Sync Gold
The Typhur Sync has a lot going for it. It comes with either two or four meat probes to handle multiple cooks at once, reads quickly, and didn’t have issues dropping its signal. The five sensors in the probes provide a robust picture of temperature changes and the base offers a clear display as well as a (very loud) alarm when a cook is done. If you don’t want to use the base, which is quite large, the Typhur app is straightforward and easy to navigate. There is a prediction feature, though it wasn’t as accurate as the Combustion prediction when we cooked chicken.
Meater Pro
Meater Pro
Of the three Meater thermometers we tested, the Pro series was by far our favorite. It read quickly and accurately during our water tests, and the improved high heat capabilities (up to 1000°F) allows use in searing cooking temperatures like a pizza oven or an open fire. It also didn’t drop signal the way the original Meater Plus did during our tests. We tested the single probe Meater Pro, but we’d also recommend the Meater Pro Duo with an extra probe.
Thermopro Tempspike
Thermopro Tempspike
This wireless thermometer is more basic than the RFX or the Combustion (but it is much less expensive). It doesn’t have a separate display and only has a single sensor at the tip of the thermometer. Its charging case doubles as a Bluetooth booster, supposedly extending its range up to 500 feet; however, we found getting that kind of range outdoors required optimal conditions. The companion app is simple but useful, with temperature readings for both what you’re cooking and the ambient temperature as well as the ability to set high and low temperature alerts.
Instant-read thermometers
Typhur Instaprobe
Typhur Instaprobe
The Instaprobe was a close second to the Thermapen One in our testing. It was hard to notice any difference in its read time, and its rotating, bright OLED display is easy to read no matter the angle of insertion. A magnet on the back makes it easy to stick on the stove, so it’s always ready to use. Ultimately, the choice of the Thermapen was a subjective one; We thought the wider base was easier to hold and use compared to the slimmer, sleeker Instaprobe. This is still a terrific instant-read thermometer.
Lavatools Javelin Pro
Lavatools Javelin Pro
For around half the price of the Thermapen One or the Typhur Instaprobe, the Javelin offers many of the same features, including an automatically rotating display and sleep function. The backlight requires pressing a touchpad, and it wasn’t quite as fast to read, but this is still a good, less expensive instant-read.
Thermometers we don’t recommend
Not every thermometer we tested earned a spot in our recommendations. Some were outclassed by newer models, others had usability issues, and a few just didn’t offer enough value for the price.
The original Meater has simply been outclassed by the newer model. We found the Bluetooth signal on this thermometer dropped occasionally, and, because it can only withstand a maximum temperature of 572°F, it isn’t as versatile as the newer Pro models.
The “Block” part of the Meater Block is an interface that is supposed to let you both monitor and set target temperatures. We found it a little small and slow to respond. We haven’t tested the Meater Pro XL, which is a version of the Meater Block updated with Meater Pro probes, and we’ll be interested to see if there are other improvements on the original design.
The probe on the Chef IQ is quite short, making insertion easy, but it still packs four sensors (three on the probe and an ambient sensor). It doesn’t come with a display, but has an app that, in addition to providing real time temperature updates no matter where you are, offers recipes with step-by-step instructions and an Instacart integration to order ingredients. But all of that felt a little fussy for something that should just have one job.
Yes, it’s inexpensive, but the ThermoWorks Thermopop offers much less than the Thermapen One. The Thermopop took five seconds to produce an accurate reading of 212°F in the water boiling; if you are looking for a budget thermometer, we think the Kizen offers much more for less money.
This thermometer has the capability of reading surface temperature using an infrared thermometer, but, even after reading the instructions, we found it confusing to use. Its price tag is also in the same ballpark as the Thermapen One and the Typhur Instaprobe and we’d suggest either of those as better alternatives.
