Q45H/64 dissolved ozone analyzer is suitable for a wide range of applications—from the standard 0-2 ppm display range required by water bottling systems or municipal water treatment to high range ones of 0-20 or 0-200 ppm. The Analytical Technology instrument can also measure DO3 concentrations as low as 0-200 ppb full scale to meet demanding applications such as pharmaceutical grade water or semiconductor wash water. Using a highly selective polarographic membraned sensor, the analyzer monitors dissolved ozone interference free. It comes in three versions: loop powered, ac operated, or battery operated. Loop-powered transmitter operates from standard 24-V dc power supplies for ozone meas-urements only. It can be integrated easily with many DCS, PLC, and SCADA systems and includes a PID output function. The ac powered systems feature PID control, relay, and dual output functions and are available with an optional pH sensor. Battery operated units with internal data logger are intended for short-term monitoring at remote sites or for proc-ess studies.
