| Keterangan: | COD ( ISO 15705: 2002) COD VARIO Setup Determination of the chemical oxygen demand index ( ST-COD) Small-scale sealed-tube Total range 0 - 15000 mg/ l Highlights ST-COD sealed tubes ready for use Suppression of chloride interference up to 1000 mg/ l 3 ranges: Low range: 0 - 150 mg/ l, meets ISO 15705: 2002 Middle range: 0 - 1500 mg/ l, meets ISO 15705: 2002 High range: 0 - 15000 Waste water parameter COD The chemical oxygen demand, ST-COD value, 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 consumed in total chemical oxidation of the organic constituents present in the water. Setup CheckitDirect COD VARIO The Lovibond® CheckitDirect COD VARIO test setup 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 Lovibond® COD VARIO tube test ( LR, MR according to ISO 15705: 2002) , it is heated in the reactor and then analysed in the CheckitDirect COD VARIO photometer. The COD-Setup comprises the CheckitDirect COD vario photometer, 25 tube tests for each of the two lower measuring ranges, a reactor for sample digestion, and a vial stand. |
