The C400 series residual chlorine sensor applies the advanced principle of constant voltage to measure residual chlorine/chlorine dioxide in water. This method utilizes a stable potential between the polarized electrodes and reference electrodes at certain different current intensities. The sensor’s reading is measured in the concentration unit by analyzing the current signal.

The C400 sensor is simple in structure. Replacement of membrane and reagent of the electrode is not required during maintenance.

The IUNI-21 dual channel analyzer is an effective option that can connect two digital residual chlorine sensors at the same time to reduce the cost of transmitter and installation space:

  • Field mounted dual channel analyzer with datalogger
  • Connect two sensors at one time
  • 4-20mA output
  • Relay output
  • Communication, RS485 (Modbus)
  • LCD visual display
  • User-friendly and attractive operating interface

Price is indicative, consisting of 1 x IUNI-21 Universal Transmitter,1 x C400 Digital Residual Chlorine Sensor and a flow cell.
