InPro 4850i – Dual-Membrane pH Electrode for the Toughest Chlor-Alkali Processes
Sensors, Process Control, Process Equipment
METTLER TOLEDO has announced the launch of its latest in-line pH electrode the InPro 4850i, designed specifically for the requirements of the chlor-alkali industry. The InPro 4850i 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 oxidizing agents that poison other sensors. This feature, combined with digital transmission of the measurement signal, means the InPro 4850i is ideally suited to chlorine production.
Unlike almost all other pH electrodes, the InPro 4850i does not have a diaphragm, therefore poisoning of the
electrode's sodium reference system is impossible. This design ensures stable measurement and eliminates sensor drift. The electrode's high quality pH-sensitive glass membrane is extremely resistant to chlor-alkali process conditions, ensuring precise pH measurement.
Although other electrodes output signals suffer from electrical interference, METTLER TOLEDO has solved this problem with the InPro 4850i and the use of Intelligent Sensor Management (ISM) technology. Sensors with ISM convert the analog measurement signal into a low-impedance digital signal which is immune to electrical interference, ensuring 100% signal integrity and stability. ISM technology also offers sensor self-diagnostics, pre-calibration of sensors, and Plug and Measure start up to simplify installation and maintenance tasks. The combination of a dual-membrane, sealed reference system and digitised signal makes the InPro 4850i a unique and the ideal solution to pH measurement in the chlor-alkali industry.
METTLER TOLEDO offers a wide portfolio of pH, ORP, DO, O2, CO2, conductivity, and turbidity sensors together with a full range of transmitters, cleaning and calibration systems.
