Decade Resistance Box

General :

Decade resistances boxes incorporate 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. Eleven position switches are employed.

 

Panel :

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

 

Resistances :

Resistances are non inductively wound properly warnished and aged for permeance of values over a long period. Imported double silk covered manganin or constantan wire is used in grade A & grade B resistance Boxes separately. Manganin has negligible temp. coefficient against copper.

 

Accuracy :

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