Municipal Water and Wastewater Treatment Product Category - Sensorex Liquid Analysis Technology

Applications such as pulp and paper or dye manufacturing and industrial wastewater treatment may expose pH probes to harsh conditions and chemicals. A differential pH probe utilizes a special measurement technique, which extends the working lifetime of the sensor in challenging applications. Replacing the sensor reference ( salt bridge ) and buffered electrolyte solution can extend working lifetime, which saves timely, costly replacements. Our SD7420CD features differential sensor technology with a direct 4-20mA output, so it can be integrated into control systems without the use of a transmitter or controller.

Chlorine exists in different chemical forms in solution, including free chlorine (hypochlorite ion and hypochlorous acid) and combined chlorine. Free chlorine is the only form that can perform disinfection, so knowing free chlorine concentration is critical for applications like water and wastewater treatment. FCL free chlorine sensors from Sensorex provide a direct measurement of free chlorine in parts per million (ppm). Using field tested amperometric technology, our FCL sensors perform continuous monitoring without any additional reagents. With a direct 4-20mA output, the FCL sensors can be used with any instrument accepting a 4-20mA input or connected directly to a PLC or SCADA.
