COD Set-Up COD VARIO

Waste water parameter COD

The chemical oxygen demand, ST-COD value (ST = small scale sealed tube), of a sample is determined by a dichromate method. The result can be considered as an indicator of the theoretical oxygen demand, i.e. the amount of oxygen required for the total chemical oxidation of the organic matter present in the water.

Setup CheckitDirect COD VARIO

The Lovibond® COD VARIO Set-Up allows precise water testing with minimized effort. The ST-COD concentration in mg/l O2 is measured by photometric detection.

After adding 2 ml of the sample to a Lovibond® COD VARIO tube test (LR, MR according to ISO 15705:2002), the tube is heated in the reactor for 2 hours at 150 °C, cooled down and then analysed in CheckitDirect COD VARIO photometer.

The COD Set-Up is a "ready to use" unit with a CheckitDirect COD VARIO photometer, 25 tube tests for LR and MR (each), the RD 125 thermoreactor for sample digestion and a tube stand.
