Surplus from an AF contract lab which was recently dismantled. The meter powers up fine but I do not have a way to test its accuracy. The case is missing feet and a handle, but is otherwise ok, see photos. Basically been sitting in storage since about 1980 or so. Buyer to pay calculated shipping rate. Thanks for your interest.
