If you’ve decided to delve into the world of candle making, having a good thermometer is essential to the process. The best thermometers for candle making report temperatures quickly on an easy-to-read display, and they’re easy to clean when you’re done. They can also boast convenient features, like pot clips and auto on and off functions, that make them simple to use.

What To Consider When Choosing A Thermometer For Candle Making

When shopping for thermometers, there are three main options to choose from. Keep in mind that candle-making waxes have different pouring temperatures, with the highest being 180 degrees Fahrenheit — the thermometers on this list easily cover this range.

  • Digital probe thermometers are inserted into the wax and display a temperature reading in as little as two seconds. Some also have pivoting probes that may make it easier to hold them at a comfortable angle.
  • Dial thermometers provide non-digital readings on a classic dial face and let you clearly see how your wax is heating or cooling. They don’t require batteries, and the one on this list features an extra-long probe that makes it easier to reach the bottom of deep pots.
  • Digital infrared thermometers are contactless and allow you to simply point the thermometer at the wax and obtain a lightning-fast reading. They’re mess-free, but they may only read the surface temperature of the wax, which could be slightly different than the temperature in the middle of the pot.

As for cleaning, candle-making thermometers are usually wiped down before washing with hot, soapy water. Most of the digital options on this list have a water resistance rating of at least IPX5, meaning they can be rinsed under lightly running water without worry.

Lastly, consider if there are any additional features that might come in handy. Some thermometers have alarm functions that glow red when you’ve reached a pre-set temperature, while others boast rotating displays that’ll automatically show the temperature right side up no matter which way it’s held — an especially nice feature for left-handed people.

Whether you’re just starting out or are an experienced candlemaker looking for an upgrade, scroll on to check out the best thermometers for candle making on Amazon.

1. The Overall Best Digital Thermometer For Candle Making


  • Alarm function when desired temperature is met
  • Clips onto the side of your pot
  • Adjustable display can be rotated up or down for optimal viewing


  • Most expensive option on the list

While this digital thermometer is one of the pricier options on this list, it has a few really convenient features that make it well worth it. First, the included pot clip and 8-inch probe mean you’ll get ongoing readings to follow the progression of your wax. Additionally, the backlit display will flash when your candle wax (or anything else, for that matter) reaches your desired temperature. The LCD display also rotates and can be tilted up or down for optimal viewing, and it has a temperature range between -58 and 572 degrees Fahrenheit. Plus, it’ll automatically shut off after 10 minutes of inactivity. An IPX5 rating means it can withstand light splashes when cleaning the probe, and you can switch between Celsius and Fahrenheit as needed.

One reviewer wrote: “This thermometer was not cheap, but it is worth every penny. It is digital and very easy to read. It has a clip so it stays put on the side of your vessel. And the best part, you can set it to notify you when a certain temperature is reached; this means that you can actually turn your back on the stove while you have something cooking! Just set it for a few degrees under what you want to reach to be safe! Wow! It cleans very easily under running water, and the housing is sturdy and durable. I have used it several times and have not been unhappy with it or disappointed yet!”
