sensors for total available chlorine

DULCOTEST

Graduated measuring ranges 0.01 – 10 mg/l

Disinfection of swimming pool water with the application-optimised DULCOTEST sensors for total available chlorine – exact measured values and high process reliability guaranteed.

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

Total available chlorine 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

The innovative diaphragm-covered DULCOTEST sensor for total available chlorine CGE3 is optimised for controlling the disinfection of swimming pool water with derivatives of chloro(iso)cyanuric acid. The sensor can also be used simultaneously with in-line chlorine electrolysis processes without disturbance from the by-products generated.

Your 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

Technical Info

Total available chlorine

  • CGE 3-mA
  • pH: 5.5 … 9.5
  • Temperature: 5 … 45 ºC

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 te 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
