However I've also discovered, to my surprise - nay, amazement - that it

out there!

I've just tried mine, and it seems to be OK so far. Just popped
it into the freezer, and it seems to show minus values.
I think it is only the indoor sensor which isn't declared to work
below 0.

Yes - As Pete C also said in an earlier post: thanks chaps: I did
mis-read the handbook.

I will try the freezer dodge: you never know, it might get the humidity
