ATIs Model Q45H is designed for on-line monitoring and control ofchlorination systems. It is available in two versions: a free chlorine monitor for drinking and cooling water systems, and a combined chlorine monitor ideally suited for ғchloraminated drinking water. The combined chlorine system can also be used in wastewater effluents where sufficient ammonia is present prior to chlorination to result in a predominantly monochloramine residual. no moving parts , so there are nopumps or motors that burn out or tubing breaks that create maintenance nightmares. All normal maintenance items are included...

Sensor Options > The residual chlorine sensors are available in two configurations:flowcell and submersion. The Free Chlorine sensor should always be used in the flowcell configuration. The Constant-Head Flowcell is used to maintain a constant flow rate and pressure at the face of the sensor. The sample inlet flow rate and pressure can vary widely without affecting the measurement. The only requirement is that the sample inlet flow rate be at least 7 gallons per hour. A Low Volume Flowcell is available for clean water application with a flow rate of 3-6 gallons per hour. The Combined Chlorine...
