Q46H/65 Chlorine Dioxide
Brand: Analytical Technology IncQ46H/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.
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.
