Resistance Box Constantan & Manganin

Eleven position switches are employed.

Decade Resistance Boxes incorporate the latest design switches so as to ensure low contact resistance.

The moving contacts are constructed from phosphor-bronze lamination to ensure long life and repeatability of results.

Panel:

An insulating panel of bakelite enclosed in an elegantly polished teak wood box.

Resistance Coil:

Manganin has a negligible temperature coefficient against copper.

Resistance Coils are non-inductively wound, properly varnished and aged for permanence of values over a long period.

Imported double silk covered manganin or constantan wire is used in Grade A and Grade B resistance boxes separately.

Accuracy:

Accuracy is brought within the field ±0.05% to ±0.1% for constantan coils (B Grade) and ± 0.02% to ±0.05% for manganin coils (A Grade)

Contact Resistance:

Contact Resistance per decade is of the order of 0.0015 ohm.
