COD Water Tester

***The Lovibond MD1010 colorimeter is directly comparible to the HACH DR300 Single Parameter Colorimeter***

Determination of the chemical oxygen demand index (ST-COD)

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)
Mercury free tube tests,in absence of chloride interference
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

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.
