I Love This Digital Thermometer So Much That I Travel With It

My husband and I go camping more than most of my friends, making us the “outdoorsy” ones in our circle. But we are far from roughing it when we do. We car camp, meaning we drive up to our campsite and park. Then we set up our huge tent (suitable for six people, though there are only two of us), our queen-sized air mattress, and a camping grill. And yes, we bring along our French press and/or travel pour-over dripper because we need coffee before our big hikes! But one thing we recently added to our list of supplies for our trips is the Lavatools PT 12 Javelin thermometer.

What Makes the Lavatools Javelin Thermometer Great?

As much as I love the ThermoWorks Thermapen ONE, the winner of our instant-read thermometer review, it’s expensive and not something I want to carry around in my duffel bag on a camping trip. The Lavatool PT12 is compact, at three-quarters the size of the Thermapen ONE and half its weight. With a foldable probe, it’s easy to use, and even more importantly, it’s reasonably priced at a quarter of the cost of the Thermapen ONE. So if I accidentally step on it, lose it, or drop it in the grill while I’m cooking up some chops, it won’t break the bank to replace it. 

It’s also super intuitive to use. Just unfold the metal temperature probe in the back and stick it into whatever you want to measure—when I’m camping, that’s usually a piece of meat on the grill or a pot of water for coffee. The digital screen in the front quickly gives you a reading. Beyond all that, the thermometer also has a magnetic back that comes in handy at home, where I store it on the side of our microwave.

It’s a fairly speedy read, giving an accurate temperature in about four to five seconds. It’s also IP65 splash-proof, which is great because I’m fairly clumsy in the kitchen. The thermometer also has a loop at the end, so I can attach it to a lanyard or my backpack. Not that I’ve done that, as I’m not that hardcore enough to go deep woods backpacking with a digital thermometer.

FAQs

What makes a good probe thermometer?

A probe thermometer should have a comfortable grip and be intuitive to use. It should read the temperature quickly and accurately, and it should also have a large digital display, making it easy to read.

What is the best probe thermometer?

Our favorite probe thermometer is the ThermoWorks Thermapen ONE; it gives accurate readings nearly instantly, has a large light-up screen, and is easy to use. It has a grippy edge that’s comfortable to hold, and the screen rotates. The Lavatools PT12 Javelin is also a great compact budget option, ideal for travel and as a secondary thermometer in the kitchen.

How do you change the temperature to Fahrenheit on the Lavatools Javelin thermometer?

The Lavatools Javelin displays temperatures in Fahrenheit or Celsius. You can change the settings by opening up the battery door by twisting it with a coin. Remove the battery to find a very small switch that allows you to change the temperature setting. Switch to whichever you prefer, then replace the battery and door.
