Picking the Best Instant Read Meat Thermometer – Factors to Consider

Now that you've decided to enter the wonderful world of instant read meat thermometers, it will help to understand more about them.

Benefits of an Instant Read Thermometer

Eating raw or undercooked meat products comes with several dangers. You can develop many different food-borne illnesses – everything from E. coli to salmonella.

Instant read thermometers can help you determine if the meat is cooked to the recommended temperatures inside. They work in any meat too, from roasts to seafood – anything with a recommended temperature range.

Keeping an accurate tab on your meals can keep you (and whoever else you're cooking for) safe. These thermometers also make things easier on you in the kitchen since you're not stressing over whether you've cooked the meat for too little time or too long.

Who Should Use Instant Read Thermometers?

In all honesty, I feel that every cook can benefit from having an instant read thermometer in their kitchen. You don't have to follow rules of thumb-hardness, guess, or cut open your meat in any way to see if it's cooked.

I know that you may be tempted to cut a little slice into that steak to make sure it's the right level of pink (or not at all). Trust me, most of us have been there. But a cut can take away that flavorful juice inside. A meat thermometer is just a small poke that won't hurt the flavors.

An instant read thermometer is quicker, too, especially compared to the traditional dial thermometers. If time is a factor and you don't want (or can't) leave a thermometer in the food, then instant read thermometers might be better for you.

Features to Look For

These digital instant read thermometers come in a few different styles, so if you want to cut down your choices to just one, consider some important features and whether they measure up to what you need in your kitchen.

Accurate and Fast Readout

The right instant read meat thermometer has both precision and speed. Check for accuracy ratings around ±1°F or ±0.9°F, which equals out to around ± -17°C. Those are generally safe ratings, so you know your meat is as close to accurate as possible.

Speed can be connected to accuracy because you don't want to sacrifice one for the other. Many quality instant read thermometers can tell you the results between 2-5 seconds. With this speed, you won't disturb the meat that long as it tries to cook.

What might be more useful is the ability to adjust between Celsius and Fahrenheit readings. This way, you can use your choice of metric or imperial units.

Temperature Range

A feature that has a connection to a thermometer's precision and speed is the temperature range it can detect. Wider temperature ranges can lead to more accurate results, allowing you to serve adequately cooked meat.

Quality instant read meat thermometers tend to have a range of -58°F - 572°F (-50°C - 300°C). I think this provides a healthy range for a variety of meats that need to be cooked at different temperatures.


What good is a digital meat thermometer that you can't read? The display is just as important as the speed and accuracy of the thermometer.

It can help if the LCD is a bit on the larger side so you can read it after a quick glance. Some of these thermometers are even backlit. This way, you won't have to hover it under the light to read the numbers. It isn't a necessary feature, but it may be a useful one.

Another useful feature in an excellent display is a rotating function. This can help you look at the thermometer in different ways without having to crane your neck since the screen rotates itself for you.

If you haven't looked at instant read thermometers before, you may be surprised to learn the probes aren't all made the same way.

You may see a thermometer with the ability to fold the probe in when it's not in use. This is usually the safer choice – there's no risk of you or anyone else accidentally poking yourself when you reach into a drawer or bag. As a father, I understand how vital it is to keep your kitchen as safe as possible with kids around, and looking for a foldable instant read thermometer can help with that.

With a folding design also comes a neat ability: reading temperatures at multiple angles. Some can turn 240° or so, allowing you to check the meat at really awkward angles – like if you don't want to pull it out of the oven or check multiple types of meat on the grill.

Of course, you can still find quality instant read thermometers with a traditional straight probe design. Just take caution when storing this type.

Reliable Construction

The best instant read thermometers are all well-designed. Being made from sturdy ABS plastic, for instance, will help keep your thermometer safe from accidental drops.

Also, an ergonomic design will allow you to keep a firmer (and more comfortable) hold on it to prevent those mistaken impacts. You want a good grip if you're going to (certainly, not recommended) try taking temperatures by reaching into a hot oven.

Some instant read meat thermometers even have a waterproof rating. You may not want to submerge them completely, but you can wash these thermometers under running water without worry about anything getting inside and ruining them.

Also, check manufacturer warranties. Some thermometers have lifetime warranties, while others come with 3-year warranties – or less. A protection policy can ensure that even if something does go wrong, you can rely on the company to set things right.


As with any digital, electronic product, a good battery is helpful. It keeps things working longer and spares you the annoyance of having to cycle through numerous batteries. Also, thermometers that use a simple, traditional battery type like AAA batteries may be easier to replace.

An auto-off function can help preserve the thermometer's battery life. Some shut off after 10 minutes or so of inactivity for those of you (like me) that may forget to turn it off.

Precautions to Using an Instant Read Thermometer

There isn't too much behind using one of these thermometers since they're meant to make your cooking easier.

Still, they may not have much use if not properly calibrated. Usually, instant-read thermometers come with instructions on how you can calibrate them – this way, you'll get accurate readings when you need them. Calibration most often involves boiling water or submerging in ice water.

This process is recommended when you first purchase a thermometer so that you can check its accuracy. Beyond that, you can use it now and then... or even before each use if you fancy.

ThermoPro TP03 Digital Instant Read Meat Thermometer

The ThermoPro TP03 Digital Instant Read Meat Thermometer is an affordable option that can provide you with accurate results to ±0.9°F. It's designed with a wide temperature range that goes from -58°F (-50°C) to 572°F (300°C). The wide range can help you use it with both indoor and outdoor cooking.

Although it claims the readout should finish within 3-5 seconds, some users have reported that it may take around 10 seconds or longer to display temperature. The display is a good size, though, and the LCD screen is even backlit so you can read it quickly.

The ThermoPro seems straightforward to operate: there are just two buttons to use, one to turn it on, and one to pop the foldable probe out. The probe offers a thinner tip to help keep you safe while using it since it is easier to insert in meat without slipping. You can also switch between Celsius and Fahrenheit.

The overall functionality is simple, and it requires just one AAA battery. There is even a 10-minute power-saving mode that will automatically turn the thermometer off to save battery life.

An issue you may encounter is with longevity. To some users, the build doesn't seem high-quality. It's made with a plastic casing that can seem flimsy, so it's uncertain how long it will hold up to frequent use. There is a 3-year warranty attached to it that can help if things go wrong, though.

Also, the food-grade stainless steel probe feels reliable. The probe rotates safely 180° for ease of use. Once you're finished and it's wiped clean, you can even stick it to your refrigerator for quick access thanks to its magnetic backing.

  • Users praise accurate results


  • Users mention a low-quality build
  • Some users report a slow readout

It has a large head with an easy-to-read LCD screen. There isn't a backlight, so you may want to use it under the lights in your kitchen. However, it does pivot at various angles so that you can check it in multiple ways. There are some user complaints that the readout is lower than it should be, though.

If you think the readout is off, you can always take a peek at the storage sleeve. It's not just useful to keep the probe safe and clean in between uses – it also lists recommended temperatures for various types of meats.

You can alternate between Fahrenheit and Celsius, and this instant read thermometer has a temperature range from -40°F (-40°C) to 302°F (150°C). This is enough of a range to cook most meats. Combined that with its pivoting head, and you can use it with ease on various grills.

As for cleaning, it is recommended that you wipe it down by hand and not submerge it underwater. There is no water-resistance to the probe, so if it were to become wet, water might seep through.

The long-term use of this probe remains in question. Some users claim that the build doesn't seem that reliable from an accuracy standpoint, while others find it breaks easily. It is an inexpensive product, though, so it may be easy to replace if anything happens.

A cosmetic note: you can choose from seven different colors. There is also a magnet on the back so you can stick it in various places for quicker access.

For safety purposes, the probe can fold into the body of the thermometer. The case is made using ABS plastic that feels reliable. However, some users mention there's a chance the probe can bend or snap from the body, but this might be more likely to occur under heavy use.

There is a 30-day warranty with this thermometer, but there's also a 3-year free replacement in case it breaks.

You may see some additional protection with this: it is water-resistant. This can make it easier to clean since you can use soap and running water to wipe it down. The battery life seems long enough, too, more so with the auto-off function that turns it off after 10 minutes.

It sports a 2-inch LCD that has a backlight so you can read it in low light conditions. The numbers are the right size for most users, too. Also, the display has an auto-rotating function. This can help you read the screen no matter which way you turn the thermometer.

Overall, the thermometer has a good build. It has a watertight seal so that nothing can get inside. Beyond that, it is rated IP67 waterproof to protect it further. The ABS plastic body is tough, as is the steel probe. Even with that, it still has a 30-day money-back guarantee and replacement policy on top of the 1-year warranty.
