The ESAW Potentiometer 4-Wire with Pencil Jockey (EEC-9889) is a high-precision educational instrument widely used in physics, electronics, and electrical engineering laboratories. Constructed with four constantan wires of 24 SWG (1 meter long), clamped under heavy brass strips (SWG 18), it minimizes end errors and ensures long-term durability.
Mounted on an 18 mm thick plywood board with mica top, the setup includes lock-type brass terminals, dual full-length meter scales, and a pointer for accurate readings. Supplied complete with Pencil Jockey, leads for connections, and a detailed working manual, this potentiometer is an essential component of electrical experiments and teaching demonstrations.
