Online Water Analysers
UV500
ONLINE WATER ANALYSER
The UV500 is a on-line water analyser based on a high resolution UV-visible spectrograph.
- 2048 pixels high resolution spectrograph scanning wavelengths from 180 nm to 750 nm is the master part of the UV500. Direct absorbance measurement for UV254, COD, BOD, TOC, NO3, Colour PO4 and Cr VI brings fast and stable measurements with a simple hydraulic circuit. Factory predefined or local multi-point calibration allows to get readings of COD, BOD and TOC under the UV alternative method for compatible applications. UV spectroscopy brings faster results than conventional methods like COD, BOD, TOC with much less maintenance once the correlation is dertermined.
- An additional circuit allows the measurement of ammonia and hydrogen sulphide on the gas phase after a stripping step. This unique method allows measurements on extremely turbid or coloured samples like activated sludge as the gas phase is not affected. A fast Fourier transform (FFT) brings an exceptional selectivity and no interference has never been reported after years of operation on many different applications.
- The patented flow cell allows very high level of suspended solid without clogging. The turbidity is automatically compensated by a dual-wavelength method.
- The UV source is a xenon flash lamp specified for 10^9 flashes that corresponds to more than 10 years of life time with one measurement every minute.
- Physico-chemical measurements like pH, ORP, dissolved oxygen, conductivity can be added to the internal measurements by using external probes. The dissolved oxygen probe is based on fluorescence method for a lower maintenance and higher stability.

UV400 ATEX
ONLINE WATER ANALYSER
The UV400 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. Mainly based on UV spectroscopy, well known for its stability and low operating cost, the UV400 ATEX can measure parameters like aromatics hydrocarbons (PAH), hydrogen sulphide, organic matter, ammonia, phosphate and turbidity. Each parameter corresponds to a specific optical module that can be selected by the user while ordering the analyser, depending on the application. 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 web-based interface allows the control and the troubleshooting at distance though an ATEX Wi-Fi or Ethernet connection using a standard browser on a computer or tablet.
