ThermoPro TP20 Review – King of Smoker Thermometers?

If you’re in the market for a relatively simple dual-probe thermometer, ThermoPro’s TP20 model might be right for you. Its intuitive design and durability make it one of the most popular thermometers in the world of smoking and grilling, and it sits at the #1 spot in our roundup of the best smoker thermometers.

In this ThermoPro TP20 review, I’ll share my thoughts on the thermometer, which I’ve been using consistently for the past several months. I’ve tried to avoid just listing features/specs and instead talk about how this thermometer meets my needs as a (borderline obsessed) home BBQ enthusiast. I hope you’ll enjoy!

What You'll Get in the Box

whats included in ThermoPro TP20 box

If you purchase a ThermoPro TP20, here’s what you’ll find when you open the box:

I also received a 10% off coupon, as well as a little card ensuring that I was happy and telling me how to get support. I can’t guarantee that those will be in your box, since they aren’t listed as contents on ThermoPro’s official site.

Quick Overview of How it Works

The photo directly above shows a pretty typical setup for smoking meat. Specifically, this was for brisket. 

On the right is the transmitter, where you plug in the probes. It has one button that turns it on/off and allows you to switch between Fahrenheit and Celsius. The display continually switches back and forth between the two probe temperatures. 

The large numbers on the receiver (left) give the readings of the two probes. Probe #1 displays the smoker’s temperature (257° F), and probe #2 is the meat’s internal temperature (49° F).

The smaller ‘TEMP SET’ numbers to the left are set by the user. You can either choose from presets or input your own custom temperatures. You are essentially setting up notifications for those temperatures, as the receiver will beep if the probe temperature reaches the ‘TEMP SET’ number. So in the photo above, the receiver will beep if either: 1) The smoker temperature starts to get hot and reaches 275°, or 2) The brisket’s temperature reaches 155° – time to wrap it soon!

With regards to the technology behind the communication, RF signals are used. This is not a Bluetooth or WiFi device, so it won’t talk to your phone.

Features Worth Mentioning

  • Upon receiving your TP20, you’ll be happy to find there’s no need to initially sync the transmitter and receiver. Just insert batteries (included), turn them on, and they will start communicating.
  • The transmitter has a metal clip/stand, which can be useful when you’re setting up your probes at the beginning of your cook. If you don’t have a table or other stand, you can just clip the transmitter to your belt. The receiver also has a stand.
  • Both the transmitter and receiver have rubber jackets. These not only provide protection but also make them easier to hold and less likely to slide off of surfaces.
  • The transmitter and receiver work within a 300 foot range. I don’t think I’ve come close to testing the limit, but I’ve had no problems putting the receiver all throughout my house.
  • There are pre-programmed temperatures for 9 types of meat, as well as varying doneness levels. Or you can choose your own temperatures, which is usually what I do.
  • The receiver LCD is backlit for when you’re cooking in the dark. It also flashes when a set temperature is reached (in addition to beeping).
  • Pitmasters from outside of the United States will be happy to hear that you can easily switch between Fahrenheit and Celsius with the touch of a button.

ThermoPro TP20 Warranty

The TP20 comes with a 1-year warranty, but you can extend it to 3 years if you register your device with ThermoPro online. Also, as their site outlines, they have a “stress free” policy when it comes to replacements. You don’t have to send anything back for repairs – instead, they will just send a new unit or probe(s) out.

It’s also worth noting that they provide customer service via email, phone, or online chat five days a week.

Useful Accessories

While the TP20 is great on its own, there are a couple accessories worth mentioning. The main thing you might consider is a case to keep the various components together. ThermoPro sells a hard carrying case that fits the TP20, and there are also similar third party cases, like this one by Caseling.

You should also think about getting extra probe holder clips, which fit between grill grates (or in oven racks). These are easy to misplace, and since you have to pinch them to move them, they get bent out of shape over time.

A Couple (Potential) Negatives

While buyer reviews for the TP20 are overwhelmingly positive, the complaints that do exist usually focus on the probes. Specifically, some folks find that they give incorrect readings or stop working completely over time. Luckily, ThermoPro appears to be committed to honoring their warranty and replacing probes. 

Personally, I haven’t had any problems with the two original probes. They have darkened over time from several smokey cooks, but still work like new. With that being said, I’m careful not to put the probes or wires over direct flames, and I’ve never submerged them in water (or left them out in the rain).

A second potential negative is the lack of “smart” device features. As mentioned earlier, there is no Bluetooth capability. This thermometer isn’t going to talk to your phone via an app (or through any other method). I personally don’t have any desire for additional high-tech features, but if you do, check out Weber’s iGrill, which allows you to check temps through an app on your phone.

ThermoPro TP20 vs TP08

ThermoPro TP20 next to TP08

I haven’t actually handled the TP08, so I decided to email ThermoPro and ask about the main differences between the TP20 and TP08. They got back to me within a day and let me know about a few differences.

First, they mentioned that the TP20 is the “upgraded” version of the TP08. The TP20 has more preset meat options. Additionally, the TP20 has a more intuitive design. If you look at the comparison photo above, you can see that the TP20 (left) shows the preset option at the top, which the TP08 does not. The TP20 also has the target temperatures to the left of the current probe temperatures.

Thermopro TP20 vs Maverick ET-733

First off, it should be said that the ThermoPro TP20 and the Maverick ET-733 are quite similar in that they are both wireless, dual-probe thermometers. Additionally, they both have roughly the same receiver/transmitter setup, and both have built-in presets for different kind of meats.

So what’s the difference between the ThermoPro TP20 and the Maverick ET-733? It mainly comes down to ease of use, with the TP20 being easier to use. The Maverick sometimes has issues syncing, and you have to use the “re-sync” button to get the transmitter and receiver on the same page. With the TP20, syncing is always automatic. Additionally, the TP20’s design is easier to navigate, with the ET-733’s menu system being more cumbersome and requiring more button presses to get set up.

Final Thoughts

I hope this ThermoPro TP20 review has been helpful. I love the intuitive, straightforward design of this model, and so far I have no complaints about accuracy or reliability. I can also rest easy knowing I have a 3-year warranty, and ThermoPro is known for responsive customer service. If you’re interested in learning more about the TP20, check it out on Amazon.

  1. Hi guys

    I have a webber style meat thermometer and after about 6 uses it for want of a better word ( shit itself ) doesn’t work anymore. Would you recommend me to buy the

    Thermo Pro T20 as a replacement????

    • Hi Pat, which Weber thermometer did you have? Was it an iGrill that works with your phone through an app? The TP20 doesn’t have any smartphone functionality, so that could potentially be a difference. Aside from that, if you just need a simple, accurate, two-probe thermometer, then the TP20 is amazing!

  2. Hey Tim I just got the T 20 and was just wondering how deep into the meat should the probes go? I noticed the Thermoworks thermometer says only 1/8” or so as the sensors are in the end of the probes. And some other models say to go in at least 1/2” or more. I understand you want to get to coolest part of the meat for accuracy. Thanks

    • Like you said at the end of your comment, I try to get the tip of the probe dead center so it’s measuring the coolest part. I’ve never had any problems this way.

  3. Hello,

    I just bought myself the 18″ Weber Smokey Grill and the TP20-S thermometer. To accurately gauge the smoker temps, what would you recommend? I was thinking of inserting the non-pointy probe and somehow securing it in one of the food grates to monitor the temps. If so, does it matter which grate (top or bottom)?

    • Hi Robbie, I would definitely recommend having one probe in the meat that you’re cooking, and the other measuring the smoker’s temperature. Did your thermometer come with a grate clip? If so, use that to set up your probe on the same level as your meat – the other empty grate might have a slightly different temperature. You could also experiment while your smoker is empty (but fired up), to see how much the two grate levels vary in temperature.

      If you check out the first photo in my article here, you can see the basic two-probe setup with one in the meat, and other to the left (in a grate clip). Definitely buy a couple grate clips if for some reason your thermometer didn’t come with one!
