The Productimeter was produced by the Durant Mfg. Co of Milwaukee Wisconsin.
Operation is simple
Streamline style is evident in the lines and details of this piece. Even the lever is streamlined-- resembling the cross section of an airplane wing.
A metal plate attached to the front of the housing provides all the important data.
The wing nut is used to reset the counter to zero. The Productimeter has an authentic patina from use in an industrial setting.
Various attachment points are provided so the Productimeter can be mounted to any type of machine.
The internal ratchet mechanism gives a robust clunk when the counter is advanced.
