A nice price for a 0-10 volt DC voltmeter. The black-plastic housing is 4" x 5-1/2" x 3-3/4" high overall, with a slanted gauge face about 3-1/2" x 4". Red and black thumbscrew terminals for positive and negative inputs. Great for small school projects or testing batteries around the house.

Sometimes leftovers provide not only a bargain, but some good clean fun. Our each is (5) 50-sheet pads of 4” x 6” Post-it® notes.
