SenTix® Top 41 & 46 pH Electrodes

Polymer Electrolyte - Double Reference System - Cylinder

SenTix® Top 41 & 46: pH Electrodes with Double Reference System and Polymer Electrolyte for pH measuring in lab, field and process

Highlights:

• PEEK shaft for maximum mechanical and chemical resistance
• most precise measurements thanks to process-proven membrane glasses and reference system
• maximum operation life thanks to a reference electrode with finely dispersed KCl solid electrolyte (Duralid®) and a double reference system

The SenTix® Top 41 & 46 electrodes are developed 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 through the special mechanical and chemical resistance of the PEEK shaft as well as the process-proven components of the measuring and reference electrode.

The reference electrode has a double junction system with a hole diaphragm and a labyrinth-like reference element. Through this design clogging of the diaphragm and poisoning of the reference system are made considerably more difficult. The saturation with finely dispersed KCl of the solid Duralid® reference electrolyte is another reason for the long zero-point stability and the associated long operation life of the SenTix® Top 41 and Top 46 electrodes. The small hole furthermore reduces the loss of KCl through bleeding, for example, and allows a fast response time.
