This digital meat thermometer with two probes is waterproof and can be used when you have things in the oven. There is a long probe that can be put into the meat you are cooking and the thermometer will be outside the microwave or oven and you can do a continual read on the temperature so that you don't have to open the oven and lose heat! I love t his feature. It also has a stick probe to just test the temp of your food when you pull it out of the oven or whatever you are cooking it in. It is backlit and digital read so easy to use and see. just clean it with soap and water after use and make sure it is clean for the next time. it also has an alarm to alert you. It can be changed between F and C and it uses a CR2450 That lasts a long time. Oh, and did i mention it has a bottle opener on the end? How cool is that? I love this thermometer!
