In this contribution a vectorial impedance meter suitable for measurements on two-electrode and three electrode electrochemical sensors is described. The impedance meter is based on basic instruments that are commonly present in an electronics lab (a digital oscilloscope and a signal generator), on a personal computer (PC), and on an 'ad hoc' developed front-end circuit. It can perform impedance measurements up to 5 MHz with a 10% maximum magnitude error and a 10 degrees maximum phase error.

Abstract
In this contribution a vectorial impedance meter suitable for measurements on two-electrode and three electrode electrochemical sensors is described. The impedance meter is based on basic instruments that are commonly present in an electronics lab (a digital oscilloscope and a signal generator), on a personal computer (PC), and on an 'ad hoc' developed front-end circuit. It can perform impedance measurements up to 5 MHz with a 10% maximum magnitude error and a 10 degrees maximum phase error.
