Energy Concepts, Inc. manufactures a wide range of test and measurement instruments that are specifically designed to withstand the rigors of the classroom. The qualities of these rugged and reliable instruments are unmatched. To meet the most critical applications, ECI's instruments are designed with a dynamic overload protection. This feature disconnects the input/output from the circuit and eliminates the need to replace fuses and downtime is avoided.

A comprehensive Operation Manual is provided with each instrument. These highly-illustrated manuals include instructions on how to maximize use of the instrument and include practical application exercises. If you need to observe a complex waveform, measure frequency, count pulses or generate a square wave, we've included easy-to-follow, "how to" procedures.

Calibration procedures, schematics, parts list and circuit analysis are covered in a very descriptive maintenance manual.

All of these features coupled with a full three-year warranty make ECI's instrumentation the right choice!
