ABSTRACT:
Spurious a.c. noise signals impressed upon an electrochemical reference electrode 3 with separate half-cell and junction electrolytes are reduced by a low impedance bypass circuit including a capacitor 25 connected in series between the electrode lead wire 15 and an inert electronic conductor, such as a graphite rod 27, immersed in the junction electrolyte solution.
