Description
Waste water parameter COD

The chemical oxygen demand, ST-COD value (ST = small scale sealed tube), of water as determined by this dichromate method can be considered as an estimate of the theoretical oxygen demand, i.e. the amount of oxygen con- sumed in total chemical oxidation of the organic constituents present in the water.

AL200 COD VARIO Photometer

With a measuring range from 0 to 15,000 mg/l O2, the AQUALYTIC® COD VARIO photometer are suitable for waste water testing.

Two LEDs light sources with long-term stability (λ1 = 430 nm ; λ2 = 610 nm, according to ISO 15705:2002), a waterproof sample chamber, a large digital display, and the user-friendly keypad ensure maximum operating reliability and convenience.
Setup AL200 COD

The AQUALYTIC® COD VARIO set-up allows highly sensitive and precise water testing with minimum effort. It measures the ST-COD concentration by photometric detection employing a linear relationship between absorbance and concentration.

After adding the sample to a AQUALYTIC® COD VARIO tube test (LR, MR according to ISO 15705:2002), it is heated in the reactor and then analysed in the photometer.
