nice bit of kit. providing it is accurate it knocks, the spots off a spirit item, and makes those LCD things look as stupid as they are. let us know how you find it!
i have two "commercial" thermometers, whilst they are more accurate than most shop bought items, they also cost close to £100 each. an investment that, for most of us, is not worth while. they cost £30 every year, or so, to be calibrated too. lol they both spend 99% of the year in a draw, but i find that for that 1% they are invaluable.
