ATI Q45C2 2E Resistivity Transmitter

On-Line monitoring of Ammonia in water is of increasing importance due to the increased emphasis on nutrient reduction in lakes, streams, and estuaries. Unfortunately, simple direct measuring sensors have not proven sufficiently reliable, and rather complicated systems have been developed to address the measurement problem. These systems can be used but require substantial maintenance and are expensive to purchase. ATI has developed a new approach to on-line monitoring of ammonia that is easier to operate and less expensive than competitive systems, but with the reliability you need.

ATI’s Residual Chlorine Transmitter is designed for on-line monitoring and control of chlorination 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 “chloraminated” 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. 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. That means no more costly reagents to purchase or flow cells that require frequent cleaning. All that’s needed is a constant flow of water across the face of the sensor, and this is provided by a sample constant-head flowcell. 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. The Q45H Chlorine Monitoring System is easy to operate, requires minimal maintenance, and will not eat a hole in your operating budget with ongoing reagent requirements or component replacement costs.
