The impedance value of a metal microelectrode for neurophysiological research is a very important parameter to characterize the recording performance of the microelectrode. The Metal Electrode Impedance Tester Model EIT-201 is a precision instrument for measuring metal electrode impedance at a frequency of 1kHz. It is designed as a bench-top model. The model EIT-201 will measure electrode impedance in the two ranges 100kOhm...1MOhm and 1MOhm...10MOhm and displays the impedance value on an easy to read high quality digital liquid-crystal-display (LCD).

A toggle switch is provided to select one of the two impedance test ranges. The EIT-201 has its own sine wave oscillator integrated which generates a very stable 1kHz sine wave test signal. The electrode impedance is measured with a constant current of 5nA.

The EIT-201 measuring circuit is largely unaffected by microelectrode offset or tip junction potentials. The EIT-201 is delivered with all required accessories like for example a stable laboratory stand for mounting microelectrodes, a beaker for saline solution, connection cables, test resistors and external power supply (100-240VAC/50-60Hz).

Furthermore the EIT-201 is a complete stand-alone system for measuring the impedance of metal microelectrodes. There are no other components necessary.
