Add to compare

The 881 Frequency Response Analyzer (FRA) is specifically designed for integrated Impedance and High Frequency Resistance (HFR) measurements. It is available for integration with various test systems, including the 600/840/850/855/857/890/910 test systems, and provides continuous, single-frequency HFR and Electrochemical Impedance Spectroscopy (EIS) analysis of an operating fuel cell. It also supports concurrent HFR measurements with current interrupt (IR drop) for orthogonal determination of cell internal or ohmic resistance, and can be integrated with the Model 910 Multi-Channel Microelectrode Analyzer (MMA) for impedance spectroscopy of electrode and sensor arrays. The 881 FRA meets or exceeds the performance and accuracy requirements needed for fuel cell testing applications, making it a versatile and precise tool for advanced fuel cell analysis.
