Ammeter
Accession Number: 2009.ph.171
The ammeter is a metal cylinder with an attached metal bottom. The top face is open, although similar models suggest glass once covered the top face. The top shows a needle and scale. The scale runs from 0-3, although under the scale it has been penciled with numbers and does not correspond to the factory numbers. The needle is fixed to a point in the middle of the face. On either side of the cylinder is a threaded terminal with a nut.
