Tech Thursdays: Ammeter

Tech Thursday is a new, reoccurring post featuring electronic and mechanical items in the Woodson’s holdings. We’re starting with an unprocessed collection of vintage equipment from the University’s Electrical Engineering Department.

An Ammeter is used to measure electrical current in a circuit. This one, a Mil-ammeter, was used for measuring smaller currents. The wood housing is still quite beautiful and can be opened by pressing a small button under the leather handle.

The DC on the face and side indicate that the device was only compatible with direct current.
