Calculating time taken to boil water

[cjl]

Is there a concern about moisture affecting the curing of the paint?

This is the big one, in my opinion. If you're putting this in an oven with curing paint, you'll be dramatically raising the humidity in the oven as the water evaporates. I'd be worried that this would affect the paint curing.

Is there any reason the device can't stay outside of the oven, with wires running to the inside of the oven where the thermocouples are?

Steam in ovens: If I want really crusty bread, I put a tray of water in the bottom of the oven. It certainly makes a difference - and it hits you right in the face if you open the door. Better check with the paint people.

But, there are plenty ways of remote monitoring of those sorts of temperatures. Do you just need extension leads on your thermocouples? You may be letting the tail wag the dog, as they say.
