Hello,

1)
Yes, also possible in the oven. According to the manufacturer "Up To 50m Range With Any Cooker", see link (6 possibilities listed): https://store-eu.meater.com/products...

2)
275°C for "Cooker" as well as 100°C for "Meat", but for us we don't think it would refer to the oven version. We also rarely set the oven to such a high temperature, about 210°C and the grill function on is often enough. Has anyone tried this in the oven?
However, certain oven manufacturers also offer alternatives to this. You could check these to see if they would be more suitable.

3)
If the internal sensor is intended for no more than 100°C, we would refrain from trying thinner pieces of meat in such a way that it would be exposed at the ambient temperature (i.e. then well above 100°C) by slipping, coming loose or the like.
However, if not set above 100°C, it might work.
