  • Description
    Digital system to monitor wastewater treatment plants, with up to 2 sensors
    Controller for small and mid-sized wastewater treatment plants including USB-interface and internal data logger– up to 2 sensors, all parameters, available anytime:
    •All parameters available (O2, NH4, NO3, COD, PO4, sludge level, …)
    •USB-interface and internal data logger by default
    •Convenient and available anytime via Ethernet-interface
    All parameters at a glance:
    The new controller DIQ/S 282 is available with different output signals. Besides the reagent-free measurement of COD, all other parameters needed for a wastewater treatment plant can be measured. By the combination of multi-parameter sensors, up to 20 parameters can be measured and displayed simultaneously.

    Up-to-date, safe and independent:
    All versions include an USB-interface and an internal data logger by default. Thereby, your valuable data and system configurations can be stored quick and easy. Stay up-to-date with our software updates free of charge and improve your controller for upcoming measurement tasks.

    Convenient and available at any time:
    Via the connection to the internet you can access your IQ SENSOR NET anytime and anywhere. Monitoring and support from remote saves time, money and nerves. Via the RS 485- and Ethernet- interfaces, the fieldbuses PROFIBUS, Modbus RTU, Ethernet/IP, Modbus TCP and PROFINET are available.

    Easy replacement:
    The DIQ/S 282 is compatible to almost all currently available components of the IQ SENSOR NET.
