Mettler Toledo InPro 4850i inline pH electrode

The InPro 4850i inline pH electrode is designed specifically for the requirements of the chloralkali industry. The electrode incorporates a sodium-sensitive glass membrane that uses the brine present in chlorine production as a reference. This reference system is hermetically sealed, providing a barrier against oxidising agents.

The electrode does not have a diaphragm, therefore poisoning of its sodium reference system is impossible. This design ensures stable measurement and eliminates sensor drift.

It also uses Mettler Toledo’s intelligent sensor management (ISM) technology that converts the analog measurement signal into a low-impedance digital signal that is immune to electrical interference, ensuring 100% signal integrity and stability. ISM technology also offers sensor self diagnostics, precalibration of sensors and plug-and-measure start-up to simplify installation and maintenance tasks.
