"ATI’s Model Q45H\/65 Residual Chlorine Dioxide Monitor is designed for on-line monitoring and control of industrial disinfection systems. Chlorine dioxide is a powerful disinfecting agent used for treating potable water, cooling water, and food processing wash water. To ensure proper disinfection while minimizing disinfection by-products, the concentration of chlorine dioxide must be precisely maintained."," Unlike on-line colorimetric and most amperometric monitors, Q45H systems utilize a membrane-covered polarographic sensor that does not require the addition of chemical reagents. The Q45H system has no moving parts, so there are no pumps or motors that burn out or tubing breaks that create maintenance nightmares. All normal maintenance items are included with each system.","Installation is simple and you can be up and running in a few hours. All that’s needed is a constant flow of water across the face of the sensor, and this is provided by a simple constant-head flowcell. The sample water is unaffected by the measurement and can be safely discharged back into the process.","The ATI Model Q45H\/65 Residual Chlorine Dioxide system responds to chlorine dioxide with minimal interference from any residual chlorine that may be present.","Available in loop-powered transmitter, AC operated analyzer, or battery operated portable versions, the Q45H\/65 is well suited for almost any chlorine dioxide measurement requirement. Even a portable data-logging version is available for temporary installation or process studies. And for even more flexibility, the instrument is available with an optional pH sensor input that allows a single unit to provide both chlorine dioxide and pH analog outputs."
