The Eico Model 1171 Resistance Decade Box is a classic testing instrument built in a sturdy metal enclosure, allowing users to select resistance values from 0 up to 99,999 ohms across five decades with 1-ohm resolution. With an accuracy rating around ±0.5% and a 1-watt power capacity, it provides reliable performance for circuit testing, calibration, and component substitution, all without the need for an external power source. Its straightforward dial-based controls make it easy to “dial in” precise resistance values quickly and efficiently.

Originally produced by EICO, the 1171 has remained a favorite tool among technicians, hobbyists, and educators for decades thanks to its durability and practical design. Whether you’re troubleshooting, experimenting, or teaching, this versatile decade box saves time by eliminating the need to swap out physical resistors.
