Integrimeter

 

a mechanical analog device designed for the mathematical analysis of graphically given functions. There are many different designs. An example is the polar integrimeter, which is primarily used for computing areas and actual values of physical quantities given graphically. In measurements using an integrimeter, the scale value of the computing mechanism is established. The given curve is traced with a stylus, noting the initial and final readings of the mechanism, and the desired quantity is computed using the proper formulas. The accuracy of these devices is about 0.1 percent.
