Differential pH electrodes designed for pH measurements in very difficult applications where standard pH electrodes cannot work because the reference electrode life would be too short as, for example, those processes including fouling or fatty substances that would deposit on the reference electrode making the measurement impossible and processes containing substances that react with traditional reference electrodes destroying them, such as Hg++, Pb++, Cu++, ClO4-, Ag+, Br-, I-, CN-, S= ions. These sensors are fully interchangeable with any other pH electrode and are suitable to be used with any pH meter and even with voltmeters and PLC. An economically interesting solution is the use of these sensors in conjunction with our standard pH meter Mod.uP01, uPLT01, uP01R, TX01, TX-HMI 01. The reference electrodes used in differential pH electrodes are not subject to the negative effect that stray currents have on inner metal electrodes of traditional reference electrodes. In all these applications, where traditional pH electrodes would have a short life, the differential pH electrodes assure long term reliability with almost no maintenance requirements. Mod.125 is a differential pH electrode, PP (Mod.125A1xx) or PVDF (Mod.125A2xx) body, 40 mm diameter, 245 mm length, suitable for immersion installation; it includes the threaded connection for the installation into Mod.SI0V immersion probe, available in various materials and different lengths. The measuring electrode has hemispheric glass membrane, the reference electrode is included inside the body and is immersed into the salt bridge, separated from it by a glass membrane.
