I picked up this unit at a hamfest as it was so cheap .
It is very sensitive, holding it by hand warms it enough to move the indicator across the dial. It says .0002mm per div.
I think it is a part of a measuring device. You calibrate it by a thumbscrew in the base , turn the screw and the needle moves across the dial.
