Name: Decade Resistance Box DRB-8
SKU: DRB-8

The Decade Resistance Box DRB-8 is a high-precision resistance calibration instrument engineered for laboratory, R&D, and industrial testing applications. Designed with 8 decades of resistance control, it spans a wide range from 1 ohm to 1.11111 megohms, making it suitable for highly accurate circuit adjustments and reference measurements.

This unit is widely used with Wheatstone bridges, Kelvin double bridges, and micro-ohm meters, offering exceptional stability and repeatability. Its resistors are made from aged non-inductive Manganin wire, ensuring low temperature coefficient, minimal drift, and consistent long-term performance.

The DRB-8 features nickel-plated, low-contact-resistance rotary switches, along with a unique 8-terminal design—providing dedicated terminals for ultra-low ohm ranges to maintain maximum measurement accuracy. High current capability on lower ranges and precision winding ensure dependable calibration even in demanding environments.

Whether for calibration labs, electrical engineering departments, or industrial testing setups, the DRB-8 delivers durable construction, stable readings, and highly repeatable resistance settings.
