Product Code : ILS-EAE-10791
Indian Lab Suppliers supplies the Resistance Box Plug Type (Constantan / Manganin Coil) (Product ID: 10791) as part of its electrical and electronics range. It is a plug-type resistance box in which coils are switched into a circuit by removing brass plugs, offered with constantan or manganin coils.
Quick Answer
The coils are wound non-inductively with double-covered resistance wire (constantan, also called Eureka, or manganin) on bakelite spools and joined through a rectangular brass block about 10–12 mm thick, all housed in a wooden box. Accuracy is ±0.05% to ±0.1% with constantan coils and ±0.02% to ±0.05% with manganin coils. Pulling a plug puts the coil under that gap into the circuit, so the resistance in use is the sum of the unplugged coils. Please confirm the total range and coil values at quotation.
