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. COD HR TT 200 - 15000 mg/l CODb) COD LMR TT 15 - 300 mg/l CODb) COD LR TT 3 - 150 mg/l CODb) COD MR TT 20 - 1500 mg/l CODb)
