Thomas Edison's Edison System Ampere Meter Thomas Edison's Edison System Ampere Meter  This Edison System ampere meter is a rare and important piece of Electrical history. The condition of this large and unusual Edison amp meter is exceptional. The scale reads up to 264 amps, off the scale, indicating this meter must have been used with a huge dynamo or motor.

This Edison meter measures approx. 10" across and 16" tall. The back of the case is cast iron. The etched glass face is flawless. The previous owner made a copy of the paper scale to cover the original scale to help preserve it. The original paper scale is behind the copy on the face in the pics. It is in nice condition.

The wooden case is original finish and in fine condition. The interior workings look like new. The wooden case is stamped in two places with Elec. Eng. Dept. L.S.J.U. which is Stanford University in Palo Alto CA.

A super nice and rare piece of American Electrical History that will display well and be a great addition to the old office, electrical, scientific or related collection! Nice!!
