The Q45H/65 residual chlorine dioxide monitor is designed for the online monitoring and control of industrial disinfection systems. It responds to residual chlorine dioxide with minimal interference from any residual chlorine.

Chlorine dioxide is a powerful disinfecting agent used for treating potable water, cooling water, and food processing wash water. To ensure proper disinfection while minimising disinfection by-products, the concentration of disinfectant must be precisely maintained.

The monitor uses a membrane covered polarographic sensor that eliminates the need for chemical reagents and minimising maintenance. Like the other ATi Q45H systems, there are no pumps or motors, which further reduces maintenance requirements.

The Q45H/65 residual chlorine dioxide monitor is fed by a constant-head flowcell that ensures a regular flow of water across the face of the sensor. The sample water is unaffected by the measurement and can be safely discharged back into the process.


Technical information, electronic monitor:

  • Display range: 0-200.0 PPB or 0-2.000, 0-20.00, or 0-200.0 PPM
  • Accuracy: ± 0.02 PPM or 0.5% of F.S.
  • Repeatability: ± 0.01 PPM or 0.3% of F.S.

Technical information, sensor and flowcell:

  • Sensor cable: 25 feet (7.5 M) standard, 100 feet (30 M) maximum
  • Response time: 90% in 60 seconds
  • Temperature limits: 0-50°C.
