Fully automatic on-line analyser for measuring concentrations of mediumsin fluids according to wet chemical methods.
The photometer orthophosphate version of the BlueMon system comprises of the following equipment: analyser unit and control and measurement electronics in a powder-coated cabinet.
Measuring cell: photometer
(wavelength and measuring gap is dependent on the method)
Method: analysis of the orthophosphates with molybdenum blue method
Wavelength: 810 nm
Measuring range: selectable option
The choice of procedure determines the number of pumps, valves and
the photometer configuration with regard to wavelength and cuvette.
Number of sample channels: selectable option
Number of free valves: dependent on procedure
e.g. use as dilution channel (e.g. H2O)
Number of peristaltic pumps: dependent on procedure
Number of process valves: dependent on procedure
