7 Best Candy Thermometers – Reviews & Buying Guide

Best Candy Thermometer

The only way to precisely make the type of candy that you want is by using a candy thermometer. Candy structure is heavily affected by its cooking temperature, so making candy without a thermometer, is simply gambling.

In addition to displaying the current temperature, many candy thermometers also come with markings on their scales to show you different levels, such as chocolate melting, softball and firm ball candies, plus many more.

There are different types of candy thermometers in the market, so you'll need a candy thermometer review like this one to give you a list of the top offers out there, and to help you make the right choice.

How to Buy the Best Candy Thermometer

How to Buy the Best Candy Thermometer

The very first candy thermometers date back to thirteenth century Germany when Bennet Muzilla used them to measure the temperature of his sugar solutions in 1272.

They've evolved since then, and come in very different sizes, shapes and designs today. You'll also find that most candy thermometers work using different principles.

To make sense of all the diversity, and be able to pick the right thermometer that'll meet your needs, you'll need to gain a better understanding of candy thermometers and their most important features.

They're as follows:

#1. Analog vs Digital

The first major difference that you'll find among candy thermometers is their functioning principle. Today, you can differentiate between analog and digital devices, and here's a look at each.

Analog Candy Thermometers are from older technologies and include both the liquid-filled and the spring dial thermometer types. Important is that each type of thermometer comes with the correct markings on its scale.

Digital Candy Thermometers are those that use digital electronic circuits to work. They'll often have digital displays and press buttons for menu selection and use. These digital models can also offer smart functions that you won't get on an analog thermometer.

#2. Automatic  vs Manual Calibration

One thing you can always be sure of is that your thermometer will offer a false reading from time to time. You can either get rid of it or recalibrate it if it offers the option.

If your thermometer offers this option, then feel free to calibrate it, else you will need to record by how many degrees the thermometer is off and simply add this divergence to your measurement next time you're using the thermometer.

It's worth noting that digital thermometers are usually more accurate than analog liquid-filled or spring thermometers. So, go digital if you want reliability, but be ready to pay a little more for it as well.

#3. Temperature Range

Another thing to keep an eye on is temperature range. While you'll typically get a candy thermometer with calibrations up to about 400 degrees F, the lower ranges tend to begin around 100 degrees F.

If you plan on using the thermometer for purposes other than candy making, then you should try to get a model with as wide a range as possible, and this usually means temperatures less than 100 degrees F.

You'll have more luck here with digital thermometers, which can even read and display temperatures below zero.

#4. Readout Speed

All thermometers are not good enough when it comes to candy making. This is because you need to know as quickly as possible when your sugar solution reaches any specific temperature.

For this reason, thermometers with slow readout speeds are not ideal. You want a thermometer that's as fast as possible, with a 4 to 6-second readout speed being ideal.

#5. Accuracy

In addition to fast readouts, a thermometer should also be as precise as possible. Analog thermometers like the spring dial type are much less accurate than modern digital thermometers, which often have accuracies of up to 0.1 degrees.

Temperature accuracy is very important in candy making because a simple 5-degree difference can turn your lovely chewy caramel into a sweet rock if the temperature goes from 235 F to 240, for instance.

#6. Material

The different types of candy thermometers that you'll find in the market are from different materials, which come with their advantages and disadvantages.

If you get a liquid-filled thermometer, then be ready to take extra care of it because it's usually made of breakable glass.

Those made from metal, are of course more durable and can withstand rough handling for longer periods than plastic or glass designs. The decision here is entirely yours alone to make.

#7. Ease of Use

No matter which thermometer you choose, it's necessary that's it's easy to use. Analog thermometers are in this respect better, because they are very simple to use, compared to digital models that often need you to study their manuals before you can use them.

#8. Price & Warranty

When it comes to price, you should make a budget and stick to it. Analog models are often cheaper, but the digital ones often come with more features and a longer warranty.

How To Test Your Candy Thermometer

How To Test Your Candy Thermometer

Given the tight temperature differences between making certain types of candy, you should understand that if your thermometer is off by just a few degrees, that you can easily make a mistake.

For this reason, you should make it a habit of always testing your thermometer before use, by following after the step by step plan below.

Step #1. Insert Into Pot

The first step is to insert the thermometer into a pot of water and bring the pot to a boil. You should take care that the sensitive tip of the thermometer lies only in the water and that it does not touch the bottom of the pot.

This is important because boiling water measures exactly 212 degrees F or 100 degrees C at sea level. What you want is to get the temperature of the thermometer while the water is boiling.

If you live in an area with an elevation that's different from sea level, then consult the chart in reference #1 at the end of this article, to find out what your ideal boiling temperature is.

Step #2. Give It Some Time

Now give it some time and let the water boil for about five or more minutes to make sure that the thermometer has the exact temperature of the boiling water.

Step #3. Inspect It

After a few minutes, it's now time to inspect the thermometer. It can either show exactly 212 Fahrenheit or the reading could as well be off by some degrees, either higher or lower.

One reason for getting different readings is that higher altitudes make water to boil at lower temperatures below 212 F. So, if you live at sea level and the reading is exact, then there's nothing else for you to do. If it's off, however, then you need to note by how many degrees that it's off.

Step #4. Taking Action

By noting how many degrees off that your thermometer is, you'll now know how much to calibrate it with or what to add or subtract to the readings you are getting when making candy.

So if your thermometer deviates by -9 degrees for instance, and you need to work with 240 degrees. You'll then subtract 9 from 240, making 231. Now, when you're cooking and your candy reaches 231 degrees, you'll know it corresponds to the 240 degrees in the recipe.

The same goes for the other side. If the water boiled above 212 degrees or your reference temperature, then you'll need to add the deviation to whichever temperature the recipe says.

So, if the recipe needs 300 degrees, for instance, and the water boiled at 220 degrees at sea level, 220 minus 212 will make eight degrees, which you'll add to 300 to make 308 degrees correspond to the recipe's 300 degrees.


We've reached the end of this candy thermometer review and you've seen the very best offers out there for helping you make candy and for other kitchen duties, as well.

You've also seen the digital and the analog offers, including their different advantages and disadvantages.

In making the last choice, therefore, it's left for you to pick the candy thermometer that best suits your cooking style and additionally meets your needs as possibly best.
