BlueMon Total Nitrogen & Total Phosphorus

Fully automatic on-line analyser for measuring concentrations of mediums
in fluids according to wet-chemical methods.
The photometer total nitrogen & total phosphorus 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)

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
