Well - my subject at last. Thermometers form part of our industrial instrument range of products.
Looking out my office window I can see racks & racks of the bloody things. Just thought you would like to know that.

Bi-metal type, vapour tension, mercury in steel, nitrogen filled systems, digital etc etc.

And if you go into your characters there is a small "o" that you can assign an alt key to so you don't have to keep typing the word 'degrees'.
