Determination of the chemical oxygen demand index (ST-COD) The Lovibond^® COD Setups allow highly sensitive and precise water testing with minimum effort. They measure the ST-COD concentration by photometric detection employing a linear relationship between absorbance and concentration. After adding the sample to a Lovibond^® COD tube test (LR, MR according to ISO 15705:2002), it is heated in the reactor for two hours at 150 °C and then analysed in the photometer. The COD Setups comprise the photometer, 25 tube tests for each of the two lower measuring ranges, a reactor for sample digestion and a vial stand. 4 ranges: Low range: 3 - 150 mg/l, meets ISO 15705:2002 Middle-low range: 15 - 300 mg/l, meets ISO 15705:2002 Middle range: 20 - 1500 mg/l, meets ISO 15705:2002 High range: 200 - 15000 mg/l
