Keep a close eye on the temperature of the oven with the MasterClass oven thermometer. Hang the thermometer on a rack in the oven and view the temperature through the glass of the oven. Find out if the oven is getting the same heat everywhere and hang the thermometer in different places in the oven to find out. With the thermometer bowl you will quickly find out why the cake is not quite cooked or whether your oven is working perfectly. The thermometer is made of stainless steel and can hold up to 300 degrees in the oven. The thermometer shows temperatures from 50 to 300 degrees Celsius and the small one shows from 100 to 600 degrees Fahrenheit. After use, you can clean the thermometer with a cloth.
