DESCRIPTION

The RS Series Resistance Substitution Box is 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 most of its competition.

The easy of use and 0.1% accuracy makes the RS Box ideal for daily verification of test equipment before measurements, troubleshooting in the field or on the factory floor.

One nice feature of the RS Series is that it uses convenient side by side, color coded, thumbwheel switches allowing 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 than a pound, these substituters are very portable and can reduce clutter on a busy lab bench.
