The electrochemical analyzer must support the following measurement methods: Open circuit potential test (OCPT), Cyclic voltammetry (CV), Linear sweep voltammetry (LSV), Chronoamperometric (CA), Tafel curve test, and Electrochemical impedance spectroscopy (EIS). Voltage range: ±10 V. Resolution: 0.005% of the potential range. Accuracy: < ±1 mV ± 0.05% of the setting value. Current range: ±2 A. Resolution: 0.005% of the current range. Accuracy: < ±0.1% of the range ± 0.05% of the setting. The scanning speed range for CV or LSV testing should meet a minimum of 0.1 mV/s to 200 mV/s. Minimum sampling interval for CA testing should be at least 0.02 ms. Frequency range for EIS testing: 10 μHz to 5 MHz. Including automatic or manual IR compensation. Instrument warranty: 2 years or as agreed to by UND
