Designed for continuous determination of chemical oxygen demand, biological oxygen demand, total organic carbon in water. DEFINED PARAMETERS AND RANGE: COD,: 0.15-10000 mg / l, BOD 0.05-100 mg / l SAC 254 (Spectral Absorption Rate at 254 nm): 0.01-100 m-1 (12 mm cell), 0.02-250 m-1 (6 mm cell) 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).
Chemical oxygen demand;
Biological oxygen consumption;
Consumption of total organic carbon.
Advantages over submerged 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 measuring range using the built-in dilution module.
