The s::can spectro::lyser. Flexibility and precision.

The revolutionary s::can spectro::lyser is a full spectrum uv/vis spectrophotometer probe. This unique technology allows you to measure the specific concentrations of numerou distinct toxins that usually require the use of several different cabinet analysers. Parameter concentrations from g/l down to the µg/l region can be measured. Additionally, spectral data can provide a statistical alarm system based on "difference from normal". This provides highly sensitive detection of potentially toxic abnormalities from the complete optical UV/Visible spectrum, enabling a level of precision and long term stability that has not been possible previously. The s::can spectro::lyser can be operated in the internal data-logger mode, via PC/laptop, or via our industrial terminal "con::stat".

The number of concurrently available parameters is eight, and pre set calibrations for many applications are readily available.

All of the functions of a high quality 2-beam laboratory spectrometer are packed into the ultra-compact and robust field instrument. s::can's advanced software options allow the utilisation of the spectral information for rapid and effective investigative work on almost any liquid stream.

spectro::lyers for Drinking Water and Enviromental Monitoring

In order to prevent any jeopardy to the drinking water consumers' health, the measure data must be available continuously and without delay.  This is the only way to allow quick reaction to changes in the water quality.  These requirements can only be fulfilled by on-line assessment of the raw and drinking water qualities.
