Not too hot, not too cold. The thermometer allows you to monitor the internal temperature of the food you bake and prepare in the Omnia. So the food always turns out perfectly! Primarily, the thermometer is used to measure the internal temperature of the prepared food. However, the Omnia thermometer can also be easily fixed in the hole of the lid using the enclosed fixing screw. Note that then only the temperature in the upper part of the oven is measured. The temperature in the lower part is higher. With the thermometer in the lid, the center of gravity changes. Therefore, lift the lid carefully.
