Potentiostats
The instruments at the center of electrochemical research — built for accuracy you can publish, with the specifications documented, not estimated.
The instruments you reach for when the measurement is hard
Highest resolution, widest EIS bandwidth, and published accuracy contour plots. The Reference line is what goes on the bench when the current is femtoamps, the impedance is milliohms, or the reviewer will ask.
