The RS Series Resistance Substitution Box are the most commonly used decade box on the market today. The RS Series is not only easier to use, but it is also priced lower than almost all of its competition.
The RS Series is an economical, indispensable set of resistors with a variety of uses in engineering, design, troubleshooting, or service fields.
One nice feature of the RS Series is that it uses convenient side by side, color coded, thumbwheel switches.allow for direct reading — There is no fumbling with multiple slide or rotary switches. Simply dial in the desired values and use!
Made of high impact plastic and weighing less then a pound, these substituters are very portable and can reduce clutter on a busy lab bench.
