General Info

IEM is an engineering oriented company located in Palatine, Illinois. We have been producing bench top test equipment for the coil winding industry since 1976. Our staff includes engineers with backgrounds in magnetic field modeling and process control engineering. We have focused on development equipment with easily used features and reliable design. Interaction with our customers has allowed us to refine ideas for product improvement and has led to a series of innovations in its product offering. The growth of the IEM line of coil test equipment has been a natural progression. Each new product has been an extension of technology used in previous designs. Our traditional product line consists of turns counters for both bobbin and toroidal coils, shorted turns testers for bobbin coils and transformer ratiometers. By applying a modular approach to circuit designs, work done in one system can be used in other products as well. This has allowed the construction of integrated test systems that provide complete testing capability at one station.
