Description

This four-page pamphlet shows model 125 of the Lasico square root planimeter, which sold in the 1940s for $135.00. It had a tracer point, unlike the later model 2000-V (2011.0043.01 and 2011.0043.02), which had a tracer lens. The pamphlet explains how to read the instrument and apply its readings to rate of flow calculations.
