The SenTix® Top 41 pH electrodes are designed for a wide range of applications in the laboratory, field and process, from wastewater to emulsions, solutions with proteins, suspensions to purely aqueous samples. This is achieved by the special mechanical and chemical resistance of the PEEK shaft and the tried and tested components of the measuring and reference electrode. The reference electrode has a double reference system with hole diaphragm and labyrinth reference element. This structure significantly complicates the blockage of the diaphragm and poisoning of the reference system. Saturation with the finely distributed KCL of the hardened Duralid® reference electrolyte is another reason for the long zero-point stability and the associated long service life of the SenTix® Top 41 electrodes. The small opening of the fiber hole reduces the loss of KCL through, for example, bleeding and provides a fast response time.
