Description

The Q46H/65 Chlorine Dioxide Monitor uses a polarographic membraned sensor to accurately measure ClO2 in water. It is particularly well suited for removing biofilms from the inside of piping systems. 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.

Two versions of the sensor are available, a sensor intended for installation in a flowcell and a sensor intended for submersion applications. Requiring minimal maintenance, sensors are easy to use and easy to maintain. an integral RTD provides temperature compensation and allows temperature to be displayed and transmitted from the monitor.

Chlorine Dioxide sensors require 2 to 4 hours of stabilization time when first installed or after membrane change. ATI offers a battery powered “polarizer” that can be used to stabilize a spare sensor so it is ready to run within a few minutes if installation. Polarizers simply plug into the sensor connector and require no adjustments.

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 1½” flow tee is also available for in-line applications with reliable constant flow and pressure conditions.
