Q46H/79S Total Chlorine Air Stripping Uni

Non-Contact total chlorine monitoring


Chlorination of potable water, wastewater effluent, and industrial cooling water is widely used throughout the world to control biological activity in the water. Disinfection of potable water with chlorine ensures that tap water is safe to drink after passing through the distribution system piping.

Wastewater disinfection helps to ensure that receiving streams are safe for recreational use, and cooling water chlorination reduces biofouling that can degrade heat transfer efficiency. This wide use of chlorination for disinfection purposes results in the need for a reliable “residual chlorine” analyzer that can operate in a variety of applications.

Key Features

  • Digital Communications. Communication options for Profibus-DP, Modbus-RTU, or Ethernet-IP.
  • Clear Display. Back-lit large LCD display provides clear visibility in any lighting condition. A scrolling second line on the display provides additional information and programming prompts.
  • Standard Method. Total Chlorine is measured using EPA recommended iodometric measurement after reaction of the sample with buffer and potassium iodide.
  • Analog Output Options. Two isolated 4-20 mA outputs are standard. One output is programmable for PID function.
  • Chemistry Module Power Options. Power options include 115 or 230 VAC, 50/60 Hz
