Dual-membrane pH probe for chlor-alkali processes

The InPro4850i combination probe for pH/ORP measurement in chlor-alkali processes, combines accurate measurement with durability. The probe's sodium-sensitive glass membrane uses the sodium concentration of the chlor-alkali process brine as a reference. This reference system has no diaphragm and is therefore immune to chlorine and other oxidizing agents that lead to failure in other electrodes. The high quality pH-sensitive glass membrane is extremely resistant to chlor-alkali process conditions, ensuring precise pH measurement. 
Intelligent Sensor Management (ISM) technology with digital signal conversion avoids high impedance signal transition to the transmitter, and ensures 100% signal integrity and stability. ISM also offers sensor self-diagnostics, pre-calibration of sensors, and Plug and Measure start up to simplify installation and maintenance tasks.
The combination of dual-membrane, sealed reference system and digitized signal makes the InPro4850i an extremely reliable and durable solution to pH and ORP measurement in the chlor-alkali industry.
