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:
