When deep-frying or making candies and jellies, the temperature of the liquid must be closely monitored using a thermometer. These thermometers must withstand much higher temperatures than oven thermometers. They are usually much larger and come with a hook to attach to the side of the pot to keep them from touching the hot metal. Temperatures usually range from 100 to 400 degrees F.

This less expensive dial probe thermometer measures temperatures from 150 F to 400 F in 50-degree increments. If your recipe specifies an in-between temperature, such as 287 F, you might have difficulty with accuracy. The temperature guides are printed on the probe storage sleeve, not the dial.
