The modular system offers space for in the field without having to go to
up to six sensor cubes for, among
others, ORP (oxidation reduction

pH value, chlorine, turbidity and
conductivity measurements.
Depending on the water quality,
these sensors need to be cleaned at
regular intervals in order to remove
limescale, iron or organic deposits

The system has been optimised to

The required liquids for cleaning or
