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 and eventually reagents depending on the parameters.

A new web-based interface allows the control and the troubleshooting at distance using an internet browser on computer, tablet or i-phone.

The UV500 is a on-line water analyser based on a high resolution UV-visible spectrograph. It allows to monitor simultaneously many different parameters for waste water treatment plants or chemical plants with an excellent stability and low operating cost.

The same spectrograph can measure organic matter, nitrate, colour, turbidity, phosphate, ammonia and hydrogen sulphide. A complementary UV-visible fluorescence module allows the measurement of aromatics hydrocarbons (PAH). Nephelometric turbidity by visible or infra-red laser diode is also available.

The full UV-visible spectrum can also be used to monitor specific chemical processes making the UV500 a ideal instrument for chemical plants.

Different materials are available for the flow cell and hydraulic parts depending on the matrix chemical compatibility.

External probes can be added for physicochemical parameters like pH, ORP, dissolved oxygen, conductivity and turbidity. 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 and eventually reagents depending on the parameters.

The CEM500 is an extractive online gas analysers dedicated to continuous emission monitoring using a very high resolution spectrograph (0.1 nm) with an ultra sensitive 2048 pixels CCD. It covers applications like DeNOx systems on power plants, generators, chemical plants, petro-chemical plants, or biogas reactors.

The CEM500 is based on UV spectroscopy that brings a higher sensitivity and stability than infra-red systems and also gives the possibility to measure several gases simultaneously, example: NH3, SO2, NO.

A high selectivity is achieved by a fast Fourier transform (FFT) on the
absorbance spectrum for all the gases having a periodic structure like
NH3, SO2, CS2 and others.

All the internal gas circuit is heated at 190°C to admit directly hot and humid combustion gas.

 There no risk of interference with H2O, CO, CO2 or CH4 as all these gases have no absorbance on the UV range.
