Respirometric OxiTop® measuring system for BOD self check measurement with undiluted samples – measuring ranges up to 4,000mg/l BOD possible
- Simple handling without dilution series
- Data security by built-in measured value memory
- Suitabe for immediate use
Complete packages for 6 or 12 measuring points for routine measurements:
The BOD measurement with OxiTop® is based on pressure measurement in a closed system: The micro-organisms in the sample consume the oxygen and generate CO2 in the process. This is absorbed with NaOH. This will cause a vacuum pressure, which can be determined as a measured value in mg/l BOD.
The sample volume used regulates how much oxygen is available in order for full BOD to run. With different volumes, measuring ranges up to 4,000 mg/l BOD can be measured.
The OxiTop® heads (green and yellow to differentiate between infeed and output) have an AutoTemp function: If the sample temperature is still too cold, the start of the measurement is delayed automatically until a constant temperature is reached, but at least for 1 hour.
In addition to the automatic saving of 5 measured values (1 value per day), you can also manually read other measured values after these 5 days have elapsed, so that control values or measurements can be tracked over time (long-term).
