If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

Measurement using OxiTop® Biological Oxygen Demand (BOD) Instrumentation is based on pressure measurement in a closed system: microorganisms in the sample consume the oxygen and form CO2. This is absorbed by NaOH, creating a vacuum, which can be read directly as a measured value in mg/l BOD.

The sample volume being tested regulates the amount of oxygen available for a complete BOD measurement. BOD measurement ranges of up to 4,000 mg/l can be measured using different sample volumes.

The OxiTop® BOD instrumentation heads (green and yellow for differentiation of inflow/outflow) have an AutoTemp function: if the sample temperature is too cold, the start of BOD measurement is automatically delayed (by at least 1 hour) until a constant temperature has been reached.

Apart from the automatic storage of 5 measured values (1 value per day), further measured BOD values can be read at all times during or after the period of 5 days, which permits the tracking of check values or measurements over longer periods. The OxiTop BOD Instrumentation measurement system also offers simple operation, improved controllability, and non-toxicity.
