Information

The esi Model 250DE Impedance Bridge is an instrument that measures resistance, inductance, capacitance, and the dissipation factor (D) and the storage factor (Q) of inductors and capacitors. The instrument is battery operated and completely portable. An internal Generator supplies ac and dc, and an internal solid-state ac-dc detector indicates bridge balance
