EISCO Two Gap Wheatstone Bridge

By: Eisco Item#: 2010833
This high-quality product is of meter bridge design and is intended primarily for the comparison of two resistance. A resistance wire negligible temperature coefficient is stretched over a meter ruler with millimeter graduations. Terminals, mounted on five plated brass strips, provide means for connecting resistors and a voltage source. These strips are separated by gaps that can be eliminated (as required) by using two further brass strips. A robust “jockey” (moveable contact) with lead is supplied for taking readings on the wire. A sprung clip provides convenient storage for the jockey. Kit includes: Wheatstone bridge, jockey, and covered wire lead with two conductive ends. Additional required equipment (not included): a center-zero galvanometer, typically reading 1mA, 01mA. (More sensitive instruments can be used but care must be taken not to create current overloads which, on analogue meters, can result in bent needles.) As well as a dry cell (or equivalent with similar internal resistance). The use of low-voltage packs or secondary cells is inadvisable as over-heating and distortion of the resistance wire can easily occur. The Wheatstone bridge apparatus measures 1 meter long.
