Bürkert Online Water Analysis System Type 8905

The Type 8905 online water analysis is a compact and modular system for monitoring all important water parameters on one platform. It is a multi-channel measuring system for Bürkert sensor cubes, based on the compact housing. Variants without housing are also available (field system). The following water parameter measurements are possible with the Type 8905 modular system: pH, chlorine, chlorine dioxide, conductivity, redox potential (ORP), turbidity, temperature and iron. These sensors can be used in a compact system or as field units. Further, almost limitless configurations in control cabinets, and according to customer wishes, can be achieved with the Type 8906 online water analysis system. The compact water analysis system enables simple installation and start-up, as well as operation and maintenance. Thanks to the Bürkert backplane system, individual cubes can be removed for maintenance without tools, while the remaining sensors continue to measure. This enables the highest system availability with maximum user friendliness. The system is operated using an integrated 7’’ touch display or the Bürkert Communicator. In addition to the display and storage of analysis parameters, further functions are possible, for example: programming simple control and regulation algorithms using the software function f(x), intervening in the process via analogue and digital inputs and outputs, carrying out sensor calibrations. Contact our experts and design your Type 8905 online water analysis system together.
