COD Set-Up MD200

The Lovibond® MD200 COD Set-Up brings together everything needed for routine Chemical Oxygen Demand (COD) testing in one convenient package. Combining the MD200 photometer with ready-to-use ST-COD tube tests, a digestion reactor and essential accessories, it provides a straightforward solution for measuring COD across a wide range of water samples.

With four measuring ranges, the MD200 COD Set-Up provides the flexibility to analyse samples with different levels of organic contamination. Low, Middle-Low and Middle Range methods comply with ISO 15705:2002, supporting routine wastewater, environmental and process water analysis.


Suitable for laboratories, wastewater treatment facilities and industrial applications, the MD200 COD Set-Up provides a complete solution for efficient, repeatable COD analysis.

Simple, Reliable COD Testing

The MD200 COD Set-Up uses the established sealed-tube method to simplify routine COD analysis and minimise sample handling. Simply add the water sample to a Lovibond® ST-COD tube, digest at 150 °C for two hours, then measure the prepared sample using the MD200 photometer.


Ready-to-use, prefilled ST-COD tubes make sample preparation straightforward and help reduce handling and the potential for operator error. The MD200 then uses photometric measurement to determine the COD concentration, providing consistent results for routine water quality monitoring.


The combination of prefilled reagents, controlled digestion and photometric analysis creates a straightforward workflow for regular COD testing.

Flexible Measurement Across Different Water Samples

The MD200 COD Set-Up supports four measuring ranges, allowing the appropriate method to be selected according to the sample and expected COD concentration. Low, Middle-Low and Middle Range methods comply with ISO 15705:2002, providing a recognised approach to routine COD analysis.


For samples containing chloride, selected ST-COD methods incorporate chemistry designed to suppress chloride interference. This provides interference suppression up to 1,000 mg/L chloride for Low and Medium Range methods and up to 10,000 mg/L for the High Range method.


Mercury-free ST-COD tube tests are also available for applications where chloride interference is not present, providing an alternative option for suitable water samples.
