In order to simplify the measurement of electrochemical noise in field applications, three identical electrodes, one acting as reference electrode (RE), are often used. However, the intrinsic noise of the RE introduces errors in the noise resistance values computed in this way. In this work, a measurement scheme, which employs two REs and is based on the properties of the crosspower spectrum, is proposed, which can reduce the error due to the RE's noise. An example of its implementation is also presented.
