Impedance measurement of a test samples
  • Air humidity-, water level- and temperature sensors monitor environment
  • Heat tank maintain samples at elevated temperatures (heat stess)
  • Different aging voltages can be applied, alternating, DC or application-specific waveforms (voltage stess)
  • Impedance analyser for electrochemical impedance spectroscopy
  • Samples are stored in individual test tubes
