For accurate determination of unknown resistances or comparison of resistances of two or more conductors. Decade dial type, with 6 dials (two dials having 4 ratio arms — one fraction and others in multiple of 1, 10, 100 and 1000 Q) and four dials with decade resistance units, total resistance 11,1100). Coils of resistance wire, double silk covered, is wound non-inductively. It is fitted with two enclosed tapping keys for battery and galvanometer. Accuracy +0.1% of unit coils.
