Product Description

The Decade Resistance Box DRB-161 is a precision instrument designed to deliver accurate and stable resistance values across six decades. With a wide range from 0.1 Ω to 111.111 kΩ, this decade box is ideal for electrical testing, Wheatstone bridge calibration, fault-finding, and laboratory measurements requiring highly precise resistance standards.

Constructed using aged manganin wire, the DRB-161 provides exceptional long-term stability, minimal temperature drift, and consistent repeatability. The resistors are non-inductive wire-wound, ensuring accuracy even in AC measurements.

Each dial employs silver-to-silver plated switches, engineered to maintain extremely low contact resistance—less than 2 milliohms—enhancing measurement precision. The inclusion of four terminals supports Kelvin connections for more accurate low-resistance measurements.

Designed for durability, every resistor in the DRB-161 is rated at 1 watt, and the system supports up to 0.5 A on the 1-ohm dial. These features make the DRB-161 an essential tool for engineers, technicians, calibration labs, educational institutions, and R&D facilities.

For users needing a reliable and high-accuracy resistance reference, the DRB-161 Decade Resistance Box offers superior performance and long-lasting stability.
