Product description

Reliable online measurement of total available chlorine – with DULCOTEST sensors.

Total available chlorine Chlorine bound to (iso)cyanic acid/isocyanurate and the free (effective) chlorine resulting from it. more in the glossary is also known as "stabilised chlorine" and is used to prevent premature decomposition by sunlight in the disinfection of swimming pool water, particularly in outdoor pools. This mainly includes compounds such as derivatives of tri-chloro(iso)cyanuric acid. After it has been metered into the water to be treated, it forms free chlorine and also (iso)cyanuric acid containing chlorine. The sensor measures both compounds, which are designated as total available chlorine Chlorine bound to (iso)cyanic acid/isocyanurate and the free (effective) chlorine resulting from it. more in the glossary.

Features and Benefits

  • Sensor for total available chlorine, also suitable for the combination of in-line electrolysis with derivatives of chloro(iso)cyanuric acid
  • Can also be used as a sensor for free chlorine without interference caused by the presence of cyanuric acid
  • Precise, real-time amperometric measurement for efficient process control (short response time)
  • Amperometric measuring eliminates interference caused by turbidity or colouration
  • Stable zero point
  • Integrated temperature compensation eliminates interference caused by influence of temperature

Field of application

  • Control of total available chlorine in swimming pools, especially outdoor pools.

    Technical Details

    Total available chlorine

    • CGE 3-mA
    • pH: 5.5 … 9.5
    • Temperature: 41 … 113 °F (5 … 45 °C)

    Sensor for total available and free chlorine CGE 3-mA

    Sensor for total available chlorine, such as derivatives of chloro(iso)cyanuric acid, without disturbance when used in swimming pools where disinfection is provided by electrolysis processes. Also suitable for use as a sensor for free chlorine. For operation with controllers with 4-20 mA input

    Your Benefits

    • Measured variable: total available chlorine, for instance disinfectant with organic chlorine, such as derivatives of chloro(iso)cyanuric acid
    • Measured variable: free chlorine without interference with the presence of cyanuric acid
    • Gold electrode to prevent faults by products from electrolysis processes where the electrodes are immersed directly into the sample water (without diaphragm)
    • Diaphragm-covered sensor (encapsulated) minimises faults caused by changing flow or substances in the water
    • Hydrophilic diaphragm guarantees the permeability of chloro(iso)cyanuric acid derivatives towards the measuring electrodes
    • The special reaction system of the electrolyte allows the total available chlorine to be determined and use at a high pH of up to 9.5
