ATI Online Analyser Q-Series

ATI’s 2-Electrode Resistivity Transmitter provides the reliable and accurate low-level measurements required for such high-purity water systems. Monitors provide large, easy-to-read LCD displays with a second display line for indication of temperature or other operational information. For those applications where results in resistivity units are preferred, Q45C2 monitors can be programmed to display readings in Meg-ohm units instead of microSiemens. The monitor employs 2-Electrode conductivity sensors with low cell constants to provide continuous measurements from 0-20 to 0-2,000 microSiemens. The 2-Electrode sensors are specifically designed for use in ultra-pure water and nonfouling applications. The sensors are available in several mounting configurations including 316SS compression fittings or sanitary-style. These sensors may also be mounted submersion-style or in a hot-tap configuration.

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.
