The Evoqua (previously Wallace and Tiernan) Depolox 400M system is an online analyser designed to measure the disinfectant concentration in drinking and other clean water applications.
It is designed to provide operators with a simple, intuitive touch panel interface for up to three measurement parameters. All popular disinfectants can be measured such as free or total chlorine, chlorine dioxide, ozone, and potassium permanganate. The analyzer is available with two amperometric disinfectant measurement technologies: DEPOLOX 5 flow cell which utilizes the fast reacting bare electrode and the VariaSens™ C flow cell which incorporates the membrane based amperometric sensor technology. Data can be easily transferred to mobile devices or incorporated into plant-wide measurement dashboard. Depolox 400M has a temperature measurement as standard and there is a choice of adding either an additional pH measurement or a fluoride measurement.
Communication with the instrument includes a standard Ethernet port which allows access to built-in web visualization of all pertinent information when connected to a local area network. An RS 485 port and four mA outputs are also standard for communication to other plant monitoring and control systems.
