ECA-series potentiostats can also be used as lock-in amplifiers.
Check out the measurement below: detection of a 500 kHz signal with 0.01 mV RMS increments.
With the built-in lock-in architecture, you can generate and detect low-level signals even at high frequencies. This enables precise tracking of tiny changes in your sensor, making it ideal for advanced applications like impedance spectroscopy, biosensing, and material characterization.
