Long range stability thanks to UV spectroscopy
Measurement within 5 seconds
Usable with unfiltered water
On-line chromium VI analysis has become essential to uphold the environmental and sanitary regulations for all kinds of water: rivers and underground water, drinking water, industrial effluent, sewage.
Reliability and stability are the main requirements of on-line analysis systems only achieved by UV spectroscopy.
- Industrial effluent
- Drinking water mixing
- Sewage works
Very low operating costs
The UV spectroscopy measuring principle requires no chemical reagent or calibration solutions resulting in very low operating and maintenance costs.
Thanks to simple, large bore tubing, turbid water with particles in suspension can be monitored without clogging risks.
An optical turbidity compensation maintains correct measurements.
Automatic cleaning system
A fully automated cleaning system prevents the measurement flow cell from becoming dirty, giving the analyser autonomy for several weeks without maintenance.
The cleaning solution (5% sulphuric acid) should be renewed once a month.
This system is more reliable than falling-stream flow cells or in-medium probes.
The xenon lamp has a lifetime of 109 flashes, equivalent to 10 years of use with one measurement every minute.
Built-in peristaltic pump
When the water is not pressurised (rivers, effluents, sewage), a peristaltic pump can be added to the analyser. It is synchronized with the measurements to increase the lifetime of the tubes.
Battery/mains power supply
For field measurements or isolated sites, a 12V built-in battery can make the analyser autonomous for about 100 measurements.
For plant applications, the battery provides total immunity against mains disturbances or power cuts, even over a long period.
The measurements are dated and stored in a static memory with a capacity of more than 10,000 measurements.
They can be tranferred later via the RS232 port on a PC without specific software using Hyperterminalâ of Windowsâ. The data are compatible with standard worksheets, particularly Excelâ, to obtain graphs easily.
Measurements can be displayed on the graphic screen showing all data obtained during one hour, one day, one week, one month or one year.
During the measurement cycle, a moving synoptic shows the operation sequence.
