Dial Type Resistance Box

Resistance Box Dial Type : The dial studs are machine cut from phosphorous bronze and laminated bush contact are made from hardened copper phosphot bronze leaves. The laminated bushed are connected to the main central contact. Individual resistors are mounted separately. The values of resistors are machine engraved or Screen Painted. Technical Details : Double covered Eureka wire is wounded on Bakelite spools. Each resistor is processed for ageing and heat treatment to avoid shifting of the values and tested individually to accuracy after fixing Carbon Resistance. Resistance are calibrated on imported testing Bridge Accuracy +0.1%
