About Resistance box

Resistance box

Resistance Box (Plug Type) is of a superior quality Heavy Brass Metal Blocks Size 7/16" are bound to Bakelite Plate by means of nuts and screws securing rigid fixation and eliminating any chance of contact error creping due to loosening of plugs and lugs which are cut to fine taper and are interchangeable. Plug heads are machine moulded, of heavy insulated Bakelite in beautiful shapes. The boxes are made of Teak-wood and nicely polished. We are renowned as one of the staggering High Power Resistance Box Suppliers in India.

Great care is taken in preparing the wire wound resistance. Selected double Covered Eureka Wire is wound in Bakelite spools. Sufficient ageing and Heat Treatment is processed through to avoid any moisture effects. Solder Joints are sealed after calibration. The Decade Resistance Box is calibrated on imported Testing Bridge Accuracy + 0.1%
