ThermoPro TP-20 Digital Wireless Thermometer Review


For years now, the ThermoPro TP-20 has been the number one selling wireless meat thermometer on Amazon. If you are new to low-and-slow cooking, then the TP-20 is the thermometer I recommend. Nowadays there are dozens of new hi-tech meat thermometers, but the ThermoPro TP-20 is still in the conversation for the best meat thermometer because of its reliability, accuracy, durability and affordability.

The ThermoPro TP-20 is a wireless duel-probe meat thermometer with an alarm function that alerts you when your meat has reached the desired internal temperature, and the second probe can be used on another piece of meat, or can measure the grill temperature so you can keep track of the ambient temperature of your charcoal smoker, pellet grill or offset smoker.

The TP-20 keeps it simple and can be used out of the box. You don’t need to spend hours reading the manual or watching videos to figure out how it works. It’s also one of the most reliable thermometers on the market, and will give you highly accurate readings.

Receiver and Remote

The TP-20 is a two-piece device with a base unit and a remote unit. The two units connect automatically when switched on and don’t need any setup. The two units are protected by a rubber case that will protect the thermometer from minor knocks and splashes.

Wireless Radio Frequency

Newer meat thermometers use Wi-Fi or Bluetooth to relay signals, the TP-20 uses Radio Frequency (RF). The RF signal is reliable and has a 300 foot range, and unlike Bluetooth thermometers, the signal doesn’t drop out between the walls of your house.

The TP-20 Display

The display on the receiver shows the temperature of the two probes in either Fahrenheit (°F) or Celsius (°C). One of the best features of the TP-20 is the pre-programmed USDA meat temperature recommendations so you can easily set your target temperatures for beef, chicken, pork, fish, poultry, ground beef, etc.

The thermometer allows you to set target temperatures for each probe, and the alarm will sound and the display will illuminate once it has reached the target temperature. The alarm is easily silenced by pushing the main button on the remote receiver.

Duel-Probes

The two probes are 4-inches in length, are 4mm thick, and have a 40-inch heat-proof cable. Some meat thermometers on the market have much longer cables, but 40-inches is sufficient. ThermoPro provide two grill clips which allow you to connect the probe to the grill grate of your cooker so you can measure the ambient temperature of the cook chamber. There is a one-year warranty on the probes, and ThermoPro will replace them if they fail in the first year.

ThermoPro make quality thermometers, and the probes are highly accurate when compared to other thermometers on the market. If a thermometer is inaccurate, then what’s the point?

The TP-20 is Simple

The best thing about the TP-20 is its simplicity. It may not have all the features of some newer, high-tech thermometers, but it is the easiest thermometer to use. Not everyone enjoys spending hours reading manuals or watching YouTube videos to figure out how something works. The TP-20 is ready to use out of the box and is easy to understand. Other thermometers can cause a lot of frustration because of the multiple modes and programming, but the TP-20 keeps it simple.

How Much Does the TP-20 Cost?

One of the best things about the ThermoPro TP-20 is the price. You could easily spend hundreds of dollars on a meat thermometer, but the TP-20 has always been affordable in the $50 range. If you’re new to meat smoking, then fifty bucks is about all you want to spend. You can always upgrade to fancy Wi-Fi thermometer later. Check the latest price on Amazon.

Build Quality

The TP20 is a solid unit but isn’t heavy or bulky. The rubber case gives the thermometer added protection and can absorb pressure quite well. The cover gives the thermometer protection from the odd splash, but isn’t waterproof. The thermometer comes in the one orange color, but that’s what makes the TP-20 so distinguishable.

Why You Need A Good Thermometer

If you’re interested in low-and-slow cooking, then a good meat thermometer will be one of your most important purchases and take all the guesswork out of cooking meat. One of the biggest mistakes people make when starting out is constantly opening the lid of your smoker/cooker. Opening the lid causes the temperatures to fluctuate and can potentially ruin your meat. A wireless thermometer will allow you to monitor the internal meat temperature and the cooker without having to open the lid and peek at the meat.

Don’t Trust In-Built Thermometers

Most smokers and cookers will have a built-in thermometer on the lid, and these factory thermometers are notoriously inaccurate. Some better quality grills may have a good thermometer, but in most cases, it’s best to use your own. If you’re serious about low-and-slow cooking, you need to know exactly what’s going on inside your meat and in the cooking chamber rather than put your trust in a factory thermometer. Also, a wireless thermometer allows you to carry a receiver so you can monitor your meat and smoker/grill while you are doing other things around the house.

ThermoPro TP08S Digital Wireless Meat Thermometer

ThermoPro also sells the TP08S, an older version of the TP-20. There isn’t much difference between the two thermometers accept for price and some minor features. The most significant difference is the TP08s doesn’t have the pre-programmed USDA recommended doneness temperatures. The presets is one of the best features of the TP20.
