Automatic differential potentiometric titration apparatus in the preceeding report(<I>J.Chem.Soc.Japan, Ind.</I>, 55, 189, (1952))dealt with an apparatus of piston-driven injector type burette, in which, when the potential difference of the solution reached a certain voltage, the potential is vaccum tabe amplified to move the relay, the piston in the burette is pushed by the mechanism of revolving shaft, connecting to the press of an automatic recording tape until the action of relay is stopped, to give the volume of titrating solution to the end point by taking 1/2 length of the recorded tape.In the present report, a smooth atomatization is effected by decreasing the rotation of shaft for diminishing the pushing speed of the piston to one-half by an automatic change of gear attached to the schaft of the relaying motor and the volume of titrating solution is automatically indicated by the counter mechanism attached to the rotating shaft.
