7 Best Candy Thermometers You Can Buy Online (2021)

When making candies, having a thermometer handy makes things a lot easy. Even a small temperature difference can make your soft fudge a rock candy! It’s true, candy making is science. And based on the temperature you cook the sugar, chocolate, etc, you get the result that you desire.

So how do you choose which thermometer is the best for you?

There are several factors to be considered before you purchase a thermometer for making your holiday treats. Here are three of the most important points based on which you can make an informed decision.


How do you want the temperature reading to be displayed? There are glass thermometers that use mercury or non-toxic alcohol level to display the readings and then there are the more sophisticated digital thermometers which display the temperature values digitally. They generally have a quick response time. But digital thermometers need maintenance, with frequent change of batteries, and are mostly not waterproof of dishwasher safe.

Pot clip

Almost all thermometers come with a clip that you can attach to the side of the pot in which you are cooking your candies. This is important, as otherwise, it becomes inconvenient to hold the thermometer with one hand and stir the liquid with the other, at the same time. Some stainless steel thermometers also come with a metal lip at the bottom that ensures that the thermometer bulb does not hit the pan at the bottom and shows a reading that’s higher than the actual temperature of the liquid.

Temperature range

While most thermometers that are available in the market are designed to measure temperature within the range of 100 to 400 °F, there are products with an upper range of 572 °F, and a much lower range starting at – 58 °F. Some thermometers also come labeled with temperature zones that indicate soft ball stage (for making fudge), firm ball stage (for making caramel), hard ball (for making hard candy), medium crack, and hard crack for making brittle candies like lollipops.

A Detailed Look at Our Top Recommended Products

These are our top six picks of the many candy thermometers available.

1. Taylor Candy & Deep Fry Stainless Steel Paddle Thermometer

This stainless steel thermometer gives consistently accurate readings, whether you are using it to fry donuts or heat caramel. The temperature range corresponding to the different stages of making candy is clearly written on the surface, making it a convenient option for both professionals and amateurs.

taylor candy thermometerbuy now


  • 12 inches in length
  • Readings are shown in Fahrenheit and Celsius (Range: 100 to 400°F)
  • Magnified display of temperature readings
  • Made of food-grade stainless steel


  • Has a heat resistant nylon handle to hold
  • Comes with a pan clip which can be attached to a pan of any size
  • Can be wiped clean with a damp washcloth
  • Dishwasher safe


  • Numbers on the display peel off soon
  • Not oven safe
  • The thermometer tip breaks easily

This thermometer is simple and easy to use. Latch it to the side of the pan using the clip, and adjust the height based on the level of liquid that’s in the pan. Make sure that the tip does not touch the bottom as that might give an erroneous reading. After its use, it’s best not to run it under cold water, as the temperature difference can crack the glass, as has happened for a few users. Other than that, this usually gives an accurate reading, whether you are measuring the temperature of your candy when it’s in the ‘thread’ stage, or the ‘hard-crack’ (when it is almost done) stage. It is 12 inches long and fits well in a pot that has enough depth. A heat-resistant holder makes it burn proof. Though it gives a magnified display of the final temperature reading, you might find it a little strenuous to read it sometimes.

2. Wilton Candy Thermometer

If you have a big family of candy lovers, this large-sized thermometer can be your best bet to making a perfectly textured candy glaze, home-made churros, or hard candies.

  • 14.7 inches long
  • Comes with a clip that can be attached to the side of the cooking pan
  • Readings are shown in Fahrenheit and Celsius (Range: 60° to 400° F)
  • Can be cleaned by washing in soapy warm water


  • Has a metal lip at the bottom that prevents the thermometer bulb from touching the pan and showing erroneous reading
  • Shows accurate readings


  • Not dishwasher safe
  • The clip that holds it to the pan is not tight enough in some cases

This thermometer is larger than most that are available in the market. It can be clipped to the side of the pan to monitor the temperature of your candy even as it’s cooking. It clips better on pans with a slightly curved top rather than on ones that have straight sides. There is a metal clip in the bottom that makes sure that the fragile thermometer bulb doesn’t touch the sides of the pan. However, this also makes it difficult for the thermometer bulb to immerse in the liquid if the quantity is too scanty. In such cases, you can tilt the pot just a bit, and stick the thermometer in manually without using the clip. Since it has an insulated hold and has considerable length, there is a low risk of you burning your hands. The thermometer can be cleaned easily with just a quick rinse with warm soapy water. Unfortunately, it is neither dishwasher nor microwave safe.

3. Polder Candy / Jelly / Deep Fry Thermometer Stainless Steel with Pot Clip

A glass thermometer with a stainless steel casing, this is a no-fuss thermometer that is easy to calibrate, easy to use, and easy to maintain. It can be used for making candies, jellies, yogurt, and deep-fried items.

  • Temperature reference guide makes it easy to monitor the temperature


  • Some find the reading inaccurate
  • The numbers on the display come off after a while

Encased in a rust-resistant stainless steel casing, this thermometer can be used without the fear that you might crack it. As with many others, this thermometer also comes with a metal stand at the bottom of the thermometer so that the bulb doesn’t hit the bottom, and always remains half an inch above it. Polder’s thermometers give you the flexibility of either latching it on the side of the pan or let it stand on the base of the pan. Either way, the readings come consistently. Some users have found the readings inaccurate. To reduce the chances of this occurring, it would be a good practice to calibrate the thermometer frequently. Dip it in a glass of ice cubes, and measure after three minutes. It should read 32 °F. If it doesn’t adjust the glass against the stainless steel casing to remove the offset.

4. GoodCook Classic Candy / Deep Fry Thermometer

A glass thermometer with a protective sleeve, this item can be safely stored and traveled with. As a bonus, the sleeve mentions the required temperature for candies and other fried items and can be a quick reference guide for those who are new into the world of candy making.

However, care should be taken that the tip, though encased in glass, does not hit the sides or the base of the pan, as it is likely to break or give a wrong reading. The thermometer has a fast response and displays the readings in just a few seconds. However, the print is small, and sometimes because of the high temperature, the inside of the glass gets foggy making it difficult for one to read the marking. The thermometer sleeve also includes a quick temperature guide for making french fries, donuts, syrup, fudge, etc.

5. CDN DTC450 Digital Candy / Deep Fry / Pre-Programmed & Programmable Thermometer

This digital candy thermometer comes with pre-programmed candy making and deep frying settings that make it easier to create that professional-looking caramel glaze.

cdn dtc450 digital candy programmable thermometerbuy now


  • Shows temperature readings between the range of 40 and 450 °F
  • Includes seven pre-programmed candy stages
  • Features a nine and a half-inch stainless steel stem
  • Comes with an adjustable stainless steel clip that can attach it to the pot
  • Comes with a plastic case for storage after use
  • Gives an alert warning when desired temperature is reached 
  • Shuts down automatically

  • There is a temperature guide on the sheath for quick reference


  • The digital readout is unclear when measuring high temperatures
  • Sometimes the reading gets stalled
  • Maintenance involves changing batteries often

This digital thermometer can greatly reduce the chances of you overcooking your candy. It is designed to give alert warnings through the cooking process. For example, if you want to cook at a certain range of temperature, you can set it in the thermometer, and it will beep when it’s about to reach the low range, again when it is in the range, and yet again when it has touched the higher range. At any point, it will show both the current temperature of the item that’s being cooked in the pot and the temperature that has been set for it to reach. Unfortunately, the display sometimes seems distorted when used to measure temperatures of over 240 °F. Some customers have complained that the reading gets stuck, and to resume it to work, they have to give it a shake. However, since the thermometer also beeps besides giving a visual reading, your candy glaze will still turn out okay. If you are not clipping the thermometer to the side of the pan, you can dip it while making sure that the tip doesn’t touch the base. This is a good buy if you are looking for a thermometer that will make sure you get your candy consistency right. With features such as alert warnings, automatic off, and pre-programmed settings, this is probably what you want if you are new into candy making.

6. Habor 022 Digital Candy Thermometer with Super Long Probe

This sleek pen-look-alike thermometer is easy to carry or store, and is the best choice if you are looking for a product that can help you not just with chocolate and jam making, but also to get accurate readings of a cooked turkey or milk.

Although when left by itself the thermometer does turn off automatically. It can be used for measuring the temperature of a diverse variety of foods including meat, barbecue, water, besides candy. The temperature reading is displayed within six seconds and a majority of the customers have found it to be accurate with an error of maybe a little over 1 °F. There is no mechanism to calibrate it, and you just have to take into account the offset while using it. The probe is long enough and convenient to use. Though there have been some complaints of the battery cover being loose and falling off. Another thing to be careful about while using this sleek item is not to run it underwater, as it is too sensitive and its performance can be affected.

7. Defull Candy Thermometer

This is a sturdy easy-to-maintain thermometer with a stainless steel casing and can be used for making candies and jams.

  • Length is 11.87 inches
  • Displays temperature in Celsius and Fahrenheit (Range: 100°F to 400°F)
  • Measurement accuracy: plus or minus 4°F
  • Uses rust-proof stainless steel
  • Includes pot clip attachment to hold the thermometer in place

To get the best results hold it in the middle of the pot, instead of clipping it on the side of the pot. The reading is pretty accurate, though some customers found that following the labels for candy stages blindly often failed to give them the desired results. So it would be best to keep an eye on the temperature value rather than follow the temperature zones. Now, the thermometer is easy to use. It can be slid into the pot, or clipped on the side. The height can be adjusted using the clip. It comes with a gourd at the bottom that protects the thermometer bulb from touching the sides or the bottom of the pan. This works best when you are making candy, jam, or syrup. There is no fuss to clean as it is dishwasher safe.
