Highlights ST-COD sealed tubes ready for use Suppression of chloride interference up to 1000 mg/l (LR & MR) up to 10000 mg/l (HR) 3 ranges: Low range: 0 – 150 mg/l Middle range: 0 – 1500 mg/l High range: 0 – 15000 mg/l 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.
