OilSys_hc – oil in water

OilSys_hc
In-Situ fluorometer for Oil in water Detection

OilSys_hc is from a new generation of highly sensitive submersible sensors for oil in water measurement. The UV fluorescence principle, used for detection, is much more sensitive than any other existing detection principle, like infrared scattering, etc. This allows the detection of very low levels of PAH (single ppb levels) for use in drinking water or condensate applications.

Typical applications are discharge monitoring of airports and factories, leakage detection and many others. The sensors can be used either in stationary or portable applications. A new innovative coating on the lenses helps prevent the optics from fouling. This together with the air cleaning option makes the enviroFlu HC very robust and deployable for long periods of time.
