Every kitchen needs to have a thermometer that has multi functions like this unit. In my classes for Cheesemaking, Sourdough, Sugar art, Chocolate-, Meat, Soap and Skincare production, Ice Cream making and MANY more food crafts, this unit will be there to service you for life. It is a digital thermometer and is water resistant. The unit can change between Degree Centigrade to Degree fahrenheit. The unit can measure sub zero temperatures and temperatures upto 320 Degree Centigrade. It comes with a nifty cap to protect the tip of the thermometer. Must have items in your house.
