Online Water Analyser
UV500 ATEX
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.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.
