Going by your "reply to" header, you must be talking about "werty".
Ignore him/her; it's a troll, and a boring one at that. Killfile
fodder.

I didn't reply at first because I don't know enough about this. I
have a plain 'ol oven thermometer. DH brought home a fancy digital
tempurature probe from work once, and it registered about the same
as the thermometer, within a degree or two. I've never heard anything
about whether the kind you get at kitchen stores have mercury in them
or not. I tend to think your "home warranty" guy is just covering his
own ass. But like I said, I'm not an expert. Hopefully, someone who
is will jump in soon...
