OxiTop IS

Measurement using OxiTop® 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 used sample volume regulates the amount of oxygen available for a complete BOD. Measure ment ranges of up to 4,000 mg/l can be measured using different volumes. The OxiTop® heads (green and yellow for differentiation of inflow/outflow) have an AutoTemp function: if the sample temperature is too cold, the start of 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 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.
