Impedance Analyzer Focuses on Fuel Cells

November 1st, 2005

The Amrel Impedance Analyzer simplifies applications in Impedance Measurement, Electrochemistry (EIS) and Fuel Cell and Battery Testing/Research. For hassle-free AC Modulation applications, the instrument outputs an AC signal superimposed onto dc Bias signal to achieve operating currents of up to 5000Adc. User-friendly features include auto-gain control for accurate small signal measurement down to the micro-ohm range, saturation protection to prevent signal overload, auto-zero calibration for increased accuracy and auto-amplitude feature for ac modulation. Precise control is available through configurable sampling intervals to balance between throughput and resolution, 4 display modes and operating current display, frequency and amplitude sweep displayed in Bode and Nyquist plots and V/I waveforms critical to EIS, and selectable gain control. Full functionality is available through VFD display/full-functional keypad and via GPIB/USB/Ethernet/RS-232 remotely using AMREL’s application program.

The analyzer offers a frequency and amplitude range with accuracy minimized at 0.1%, and distortion less than 0.1% to provide precise signal generation. Impedance analysis applications can be realized through a frequency sweep of .1Hz ~ 20kHz and an amplitude sweep of up to 1Vrms and 5Vdc bias, capturing critical test data down to the micro-ohm range displayed on a log/linear scale.

Additional specifications include:

• Four modes:
  • Ch 1 Real and Imaginary Impedance Values
• Ch 2 Real and Imaginary Impedance Values/Impedance measurement in polar form (gain and phase)/measurement in rectangular form (real and imaginary)
