Chlorine / Chlorine Dioxide Analyzer and Control System

The EMEC Chlorine Analyzer Control System, offers ease of use, accuracy and reliability for the monitoring and control of Chlorine in water. Using the EMEC LDSCL PLUS analyzer and controller, and the latest in Amperometric Cell Technology, Chlorine ppm readings are continuous and updated every second. The same controller can be used for Chlorine Dioxide, incorporated with a different sensor. Built-in pH, and temperature compensation are standard.

The System below consists of the Controller, Filter, Flow Cell and Chlorine Sensor:

  • pH, and Temperature Compensated
  • 15 PSI (1 Bar) Max Pressure, or 115 PSI (8 Bar) for SCL17/18 Self-Cleaning Probes
  •  Chlorine Measurement Models:
    • SCL3S for free chlorine – Sodium Hypochlorite (organic and inorganic) for fresh water (0 – 20.00 ppm)
    • SCL3N for free chlorine – Sodium Hypochlorite (inorganic) for fresh water (0 – 2.000, 20.00 or 200.0 ppm)
    • SCL3N/0.5 for zero inorganic free chlorine – ideal for absence of Chlorine measurement for fresh water (0 – 0.500 ppm)
    • SCL18 self-cleaning for free chlorine – Sodium Hypochlorite (inorganic) for dirty water (0 – 2.000 or 20.00ppm)
    • SCL18/0.5 self-cleaning for zero inorganic free chlorine – ideal for absence of Chlorine measurement for dirty water (0 – 0.500 ppm)
    • SCL8 for total chlorine (0 – 2.000 or 20.00 ppm)
  • Chlorine Dioxide Measurement Models:
    • SCL2 for chlorine dioxide (0 – 0.500, 2.000 or 20.00 ppm)
    • SCL17 self-cleaning for chlorine dioxide, for dirty water (0 – 0.500, 2.000 or 20.00 ppm)
