Closing the loop on chlorine dosing calls for a sensor that answers in seconds. This membrane-covered amperometric analyzer reaches 90 percent response in under 60 s and compensates for pH between 6.0 and 9.0. Select a 0–2 or 0–20 mg/L range, and connect over 4–20 mA, Modbus or Ethernet to your dosing pumps and SCADA.
