This is the thermometer of choice used by the lab where I last worked. It can be calibrated and is very accurate. I use it to check all the other thermometers and controllers that I use. Mine was calibrated to 100°F by a lab tech friend. They are currently on sale for $19.
Thanks,, now I have to decide, do I incur the wrath of the daughter of the wicked witch of the south and buy a second thermometer or wait on the one I have coming...Hmmmm
