Catalogue No: 1091140/1

Works on the principle of variation in the resistance of a conductor with length and useful as a potential divider for various electrical experiments such as in null point detection. Comprising a 24SWG bare constantan wire stretched along a meter rule (graduated in millimeters) and is clamped to brass plates. The clamping system is designed to make electrical contact with the wire at the exact ends of the scale thus virtually leaving no margin for end errors. The terminating strips are provided with heavy-duty 4mm socket terminals.
Supplied with jockey.

Catalogue No: 1090800/2

Comprises circular dials mounted, inside sturdy Aluminum extrusion case. Each dial has 10 resistances, with a knob at the top which rotates with positive click stop to select the desired value as indicated alongside index mark on the knob. Provided with a pair of 4mm sockets for connecting the resistances across a circuit and a green safety socket for earthing. Multiple dials are connected in series to add to the total resistances of each dial. Accuracy +-1%.
Note: Other ranges also available on specific request.
