X-Y-Z positioning system

Potentiometric pH sensors are probably the most employed in corrosion studies. The simplest design is based on the introduction of the selected ionophore after silanization of the tip of the pulled capillary in which a silver chlorinated wire is immersed to serve as the internal reference electrode. This kind of microelectrodes can be mounted on the X-Y-Z positioning system to control the position and program the sweeping of the microelectrode. " " ...
