This company made precision instruments ,thermometers, barometers, ect, for medical, engineering and industrial use !! They were in business till the 70`s not sure how much later but they may still be around !! Try looking for a catalogue !! The probe on yours doesn`t have a point so sticking it in a brisket might be difficult !! Figuring out what this one out of many was used for is not an easy task !! Just call it an industrial thermometer !!
