Product Code : JA-SI-8096

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.
