In-line analyzer AquaTOS-UV-254
FLOW ANALYZER AQUATOS-UV-254
Designed for continuous determination of chemical oxygen demand, biological oxygen demand, total organic carbon in water.
APPLICATIONS:
- industrial water;
- waste water treatment plants;
- industrial waste water;
- river water.
DEFINED PARAMETERS AND RANGE:
- HPK,: 0.15-10000 mg / l, BOD 0.05-100 mg / l
- ZAS 254 (Spectral Ratio
- Absorbances at 254 nm): 001-100 m-1 (cell 12 mm), 02-250 m-1 (cell 6 mm)
- Total Organic Carbon: 00.6-16000 mg / l
- Other ranges on request
The measuring principle is based on the absorption of UV radiation by molecules of aromatic hydrocarbons at a wavelength of 254 nm.
Turbidity, suspended solids or impurities in the flow cell are automatically compensated for by differential measurement with a second sensor with a different wavelength (590 nm).
ADVANTAGES COMPARED TO SUBMERSIBLE SENSORS:
-
Possibility of two-stream analysis;
-
Automatic calibration and verification of the correctness of the readings, which is not possible with submersible sensors;
-
Automatic cleaning with a programmable cycle;
-
Wide measurement range using the built-in dilution module.
