The UV600TPTN is an on-line water analyser to simultaneously measure total phosphorus and total nitrogen based on a wet-chemical oxidation in compliance with EN ISO 6878 and Standard Methods 4500-P, 4500-N and 4500-NO3. It belongs to a family of analysers for total parameters: TP (Total Phosphorus), TN (Total Nitrogen) and TOC (Total Organic Carbon).

The UV500 ATEX, based on a modular concept, allows to monitor one or several parameters for process water, cooling water or waste water. The special enclosure and air purge system allows to use it on hazardous areas classified "Ex" like refineries and chemical plants. Based on UV spectroscopy, well known for its stability and low operating cost, the UV500 ATEX can measure parameters like aromatics hydrocarbons (PAH), hydrogen sulphide, organic matter, ammonia. Each parameter corresponds to a specific optical module or software that can be selected by the user while ordering the analyser, depending on the application.A colorimetric module allows the measurement of phosphate or chromium VI.Probes can be added for physicochemical parameters like pH, ORP, dissolved oxygen and conductivity.

In regards of the new regulations defined by IMO (international Maritime Organization) in 2020, ships must continuously control their emissions from fuel oil combustion. Global Sulphur content shall not exceed 0.5 % in ships’ fuel oil unless an exhaust gas cleaning (EGC) system is provided. The wash water resulting from the cleaning of the scrubber used to reduce the amount of pollutants in the exhaust stream is also subjected to regulations as it is discharge into the open sea. Discharge water must be effectively monitored before returning to the sea in order to limit its impact on marine ecosystems or environment. The MEPC 259(68) standards give specific criteria for water quality parameters.

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 river monitoring stations 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. ne.

The UV500-Compact 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 river monitoring stations with an excellent stability and low operating cost. The same spectrograph can measure organic matter, nitrate, colour, turbidity and phosphate.

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, nitrate, aromatics hydrocarbons (PAH), colour, hydrogen sulphide and chlorophyll.

The UV300 is a cost effective water analyser for applications focused on one or two parameters. Mainly based on UV spectroscopy, well known for its stability and low operating cost, the UV300 can measure parameters like organic matter, nitrate, colour, aromatics hydrocarbons (PAH).A complementary module allows the measurement of PO4, Cl2, NO2, Fe, Al by colorimetric method and turbidity by 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.

The UV300-5D is a pre-defined configuration of the UV300 analyser dedicated to drinking water monitoring.

The EL300 is a universal water controller based on a modular concept. The EL300 can adapt to many different probes and configurations, mono or multi-channel. It allows the connection of one or several probes for each parameter among pH, ORP, dissolved oxygen, conductivity, chlorine, total suspended solid (TSS), total dissolved solid (TDS), temperature and turbidity in the limit of 16 channels. A very user-friendly interface can display all the values as well as graphs of the recorded values with periods from 10 minutes to one month. A USB port allows to transfer the recorded measurements that may be imported to Excel for treatments or graphs. A new web-based interface allows the control and the troubleshooting at distance using an internet browser on a computer, tablet or i-phone.

The EL200 is a configurable water controller that can adapt to many different probes and configurations, mono or multi-channel, among pH, ORP, dissolved oxygen, conductivity, chlorine, turbidity, total suspended solid (TSS) and temperature.
