Second Sense lead cable

S2 and BiPot

Nexus includes a Second Sense lead (S2) and an optional BiPotentiostat (BiPot) module.

S2 – Additional voltage (potential) measurement point

BiPot – Independent second working electrode for simultaneous current measurement

These two features are independent and serve distinct purposes:

S2 (Second Sense Lead)
S2 acts as an additional voltage-sensing input, with the same specifications as the main reference electrode. It measures the potential at a specific point in the cell and, because the current at that point is known, it can also be used to calculate impedance.

BiPot (BiPotentiostat Module)
The BiPot module introduces a second working electrode (WE2), operating versus the same reference and counter electrodes as the main channel. In BiPotentiostat mode, both working electrodes (WE1 and WE2) are recorded simultaneously. WE2 operates in potentiostatic mode, meaning it can independently control its potential and measure its current.
