The AMU Series of 1/4 DIN panel-mounted pH/ORP/temperature analyzers from SWAN Analytical can be used with inline sensors, flow cells or in situ probe-type sensors. The analyzer includes automatic or manual sensor cleaning systems, analog and digital communications options, proportional control and alarm output relays, and an input relay. It can be used in wastewater treatment tanks, membrane treatment systems, final effluent or potable water source water and clarifiers. It is useful for reports since it records data, calibrations, events and alarms internally. This data can be accessed via PC directly from the analyzer or be captured by the SCADA system using the digital communications options. It compensates for temperature drift of its electronics or errors in the software or hardware. 847/229-1290; www.swan-analytical-usa.com.
