DIQ/S 282/284

Controller for small and mid-sized wastewater treatment plants including USB-interface and internal data logger– up to 4 sensors, all parameters, available anytime

All parameters at a glance:

The new controller DIQ/S 282/284 is available as 2- (DIQ/S 282) or 4-channel-version (DIQ/S 284). 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 save 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 282/284 is compatible with almost all currently available components of the IQ Sensor Net.
