METTLER TOLEDO Process Analytics announces the launch of its InPro 4850i pH electrode designed specifically for the requirements of the chlor-alkali industry.
Greifensee, Zurich -- (SBWIRE) -- 05/28/2012 -- The InPro 4850i features a sodium-sensitive glass membrane that uses the brine present in chlorine production as a reference.The hermetically sealed reference provides 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 tochlorine 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 designinnovation ensures stable measurement and eliminates sensor drift. The electrode's high quality pH-sensitive glass membrane is extremely resistant tochlor-alkali process conditions, enabling precise pH measurement.
The output signal from traditional dual-membrane pH electrodes suffers from electrical interference. Itssodium-sensitive glass has high impedance. Factoring in additional impedance of the cable between sensor and transmitter means that the signal from the sensor ishighly sensitive to interference from surrounding equipment. Touching or approaching the measurement system can create a change in the output.
METTLER TOLEDO's Intelligent Sensor Management (ISM) technologysolves this challenge.. 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.
This unique combination of dual-membrane, sealed reference system and digitized signal makes the InPro 4850i unique and the ideal solution to pH measurement in thechlor-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.
