FLOW ANALYZER AQUATOS-UV-MOS
Designed for continuous determination of nitrates in water (NIT).
The measuring principle is based on the intense absorption of UV radiation with a wavelength of 220 nm by compounds containing an MO bond (nitrates).
Turbidity, suspended solids and impurities in the flow cell are automatically compensated for by a reference measurement at a different wavelength (270 nm).
0.02 - 1000 mg / l
Analytical systems are mounted in block-boxes or cabinets manufactured by TOS-Technologies LLC with the necessary life support systems.
