The UV400, based on a modular concept, allows to monitor simultaneously many different parameters for waste water or drinking water treatment plants as well as river monitoring stations. Each parameter corresponds to a specific optical module that can be selected by the user while ordering the analyser, depending on the application.

Mainly based on UV spectroscopy, well known for its stability and low operating cost, the
UV400 can measure parameters like organic matter, ammonia, aromatics hydrocarbons (PAH),
nitrate, colour, hydrogen sulphide and chlorophyll A. Complementary modules allows the measurement of phosphate by colorimetric method and turbidity by a laser diode.

External probes can be added for physicochemical parameters like pH, ORP,
dissolved oxygen and conductivity.

Thanks to its automatic cleaning system and its extremely long life
time lamp, the maintenance is roughly limited to the periodic
refill of the inexpensive cleaning solution.

A new web-based interface allows the control and
the troubleshooting from internet on laptop,
tablet or i-phone.
