ECA-Zero
Potentiostat without EIS, with the same 24-bit ADC as the rest of the range.
A potentiostat without impedance spectroscopy. It runs voltammetry, amperometry, and open-circuit measurements with the same 24-bit ADC and ±2 V, 50 mA range as the rest of the ECA series.
Highlights
- 24-bit ADC
- ±2 V, 50 mA
- USB powered
- Same ADC as the ECA-5M
Example measurement
Amperometry, −40 to +40 pA in 10 pA steps
Recorded on an ECA-Zero. Test currents were generated by applying controlled bias voltages across a 100 MΩ resistor; 1 mV corresponds to 10 pA. Measurement example, not an accuracy specification.
