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).

APPLICATIONS:

Household wastewater treatment plants
Industrial waste water
Process water
River water

MEASUREMENT RANGE:

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.

ADVANTAGES COMPARED TO SUBMERSIBLE SENSORS:

Measurement interval from 1 minute;
Reagent-free technique;
Reliable operation without maintenance for several weeks;
High measurement accuracy even at low concentrations;
Simple maintenance that does not require special skills;
Touch screen control;
Automatic calibration and verification of the correctness of the readings;
Automatic cleaning with a programmable cycle;
Analysis in a wide range of measured concentrations;
Analysis of two or more streams on one device;
Low running costs.
