The LS Series Inductance Decade Box is the most commonly used inductance substitution box on the market today. The LS Series is not only easier to use, but it is also priced lower than almost all of its competition.
The LS Series is an economical, indispensable set of inductors with a variety of uses in engineering, design, troubleshooting, or service fields.
One nice feature of the LS 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 then a pound, these inductance decade boxes are very portable and can reduce clutter on a busy lab bench.
