Can I use a candy thermometer in the oven?

Candy thermometers are not oven-safe, so it’s not recommended to use one to check the temperature in an oven. The candy thermometer is only compatible with temperatures between 100 and 400 degrees, and the oven temperature is above this range. And this temperature change may cause the candy thermometer to crack in the oven.

Can You Put a Candy Thermometer in the Oven? 

You should not put a candy or sugar thermometer in the oven as its usage is bound to a specific temperature limit which you should not exceed. The oven temperature is more than 400 degrees, so there is a risk of the thermometer not giving accurate data.

As a result, Candy thermometers should not be used in ovens since they can pose a safety risk. The candy thermometer won’t give accurate readings if it reaches above the temperature limit; it could break in the oven. 

Also, the candy thermometer uses its bottom to measure temperature, which is made up of glass. So when the oven blasts the heat, the rapid temperature changes, and high heat can cause the glass thermometer to crack.

If you want to calibrate your oven, then use proper tools instead of substitutes as there is less chance of accuracy, and the thermometer might also break. When a product isn’t meant for a specific use, you should avoid using it. So, never place your candy thermometer in your oven if you don’t want an explosion or thermometer breakage.

Ensure this thermometer does not undergo extreme temperature variations as it will shatter on high heat. Also, do not let the thermometer touch the bottom of your pan or pot.
  • The stainless steel thermometer has a rust-free steel body, but it is made of glass from the inside. There is metal mercury inside both thermometers that measure the temperature by expanding and contracting according to temperature.

Involving inventions have brought us digital candy thermometers for more accurate data and convenient usage. The temperature range of a digital thermometer is a bit more than a regular glass or stainless steel thermometer. It is made of silver, so it is unlikely to shatter due to high temperatures. 

As the product has a bit high temperature withstanding capacity and the producers claim it to be safe for oven use, you can use it in the oven for oven calibration. The material of the digital candy thermometer makes it a versatile product and convenient for different cooking processes.
