An Alternative to the Use of a Zero Resistance Ammeter for Electrochemical Noise Measurement: Theoretical Analysis, Experimental Validation and Evaluation of Electrode Asymmetry

Corrosion Science, 2013
AbstractThe measurement of current and potential noise during corrosion generally requires two electrodes, coupled by a zero resistance ammeter (ZRA), and a reference electrode. Statistical methods then enable estimation of the noise resistance, if the electrodes are identical.

Communication—On Zero-Resistance Ammeter and Zero-Voltage Ammeter

Journal of the Electrochemical Society, 2017
Zero-resistance ammeters (ZRAs) are often used to measure coupling currents. The ZRAs may have a resistance of 50 kohm when they are used to measure currents near 1 nA, so calling them ZRA is only an appropriate when the measured current is high, but not appropriate when the current is low.

Zero Resistance Ammeter of Metallic Alloys in Aqueous Solutions

Optik, 2007
Abstract In the present work, the corrosion current density of a low carbon steel, a pure aluminum, a stainless steel, a copper–nickel alloy were obtained in 1 M NaOH, 1 M KCl, 1 M NaCl, 1 M H2SO4 solutions, respectively. The obtained corrosion data from the optical interferometry technique, as a zero resistance Ammeter were compared with corrosion ...

Laser Optical Interferometry as a Zero Resistance Ammeter: Fundamental and Applications

Nondestructive Testing and Evaluation, 2003
It is well known that electronics instrumentation, i.e. Ammeter, Potential-meter, have been used for years to measure electrochemical properties of metallic electrodes in aqueous solutions. One of the disadvantages of using electronic instruments for the measurement of electrochemical properties is the invasive nature of those instruments to the ...

An Electronic Zero Resistance Ammeter With Instantaneous Null Characteristics

Corrosion, 1971
A brief review is made of the operating principles and shortcomings of the traditional manual null balancing zero resistance ammeter. It is demonstrated qualitatively how this instrument, when off balance, can affect the validity of corrosion current data obtained on short circuited elements. The design and operating principles of a modified electronic
