Description

Chlorine Dioxide is a powerful oxidizing agent used for disinfection of potable water, cooling towers, and food wash water. It is also widely used for the bleaching of pulp in paper mills. As a disinfectant, ClO2 has advantages over chlorine in that it does not react with ammonia and many organic compounds while proving more effective at controlling bacteria, spores, viruses, and cysts. It is particularly well suited for removing biofilms from the inside of piping systems.

ATI’s Model Q46H/65 Chlorine Dioxide Monitor provides an economical and reliable measurement system for water quality monitoring and controlling ClO2 treatment systems. With a variety of outputs including 4-20 mA analog, PID control and digital communications, the Q46H/65 is adaptable to any ClO2 application.

Key Facts

  • pH Input Option.Enables monitor to measure both chlorine dioxide and pH. One analog output may be assigned to the pH measurement, allowing remote monitoring and recording of both variables.
  • Flexibility. Programmable range options from 0-200 PPB up to 0-200 PPM provide maximum application flexibility.
  • AC or DC Power Options. Power options include universal 100-240 VAC or 12-24 VDC.
  • Analog Output Options. Two isolated 4-20 mA outputs are standard, with an option for a third output if required. Default setting provides analog outputs for ClO2 and temperature.
  • PID Output. Standard PID control function assignable to one analog output.
  • Digital Communications. Available for either Profibus-DP, Modbus-RTU, or Ethernet-IP.
  • Relay Contacts. Three SPDT relays are standard, with relay functions programmable for alarm, control, or trouble indication. Three additional low power relays available as an option.
  • Flexible Mounting. NEMA 4X (IP-66) enclosure is suitable for wall, pipe, or panel mounting.
  • Clear Display.Back-lit large LCD display provides clear visibility in any lighting conditions. A scrolling second line on the display provides additional information and programming prompts.
