ATI Q46H-65 Chlorine Dioxide Monitor
Construction:
On-line Monitoring & Control for ClO2 Disinfection Systems!
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.
INTERFERENCE-FREE CIO2 MEASUREMENT
Q46H/65 monitors use a polarographic membraned sensor to accurately measure ClO2 in water. The sensor operates much like a battery, generating current that is linearly proportional to the concentration of chlorine dioxide in solution. A ClO2 permeable membrane isolates the sensor from the measured sample and insures that the measurement is interference free. |

ClO2 Monitoring with Direct Membrane Sensing!
SENSOR & FLOWCELL OPTIONS
Chlorine Dioxide sensors require a steady flow of sample across the membrane at the tip of the sensing assembly. ATI offers a number of options for flowcells, including the standard constant-head overflow system, a sealed flowcell for pressures up to 50 PSI, and a low-volume flowcell where low sample flow is important. A 1-½” flow tee is also available for in-line applications with reliable constant flow and pressure conditions. For simplicity of installation, complete flow control assemblies are available.
PRODUCT FEATURES
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.
