Respirometric measurements with OxiTop®

For decades, OxiTop® has been a well-established term in the measurement of Biochemical Oxygen Demand (BS) for self-monitoring and advanced manometric respiration testing. The new OxiTop®-i is excellently suited for the self-monitoring measurement of BOD in undiluted samples according to DIN EN 1899-2. In addition to BOD, the OxiTop® IDS can map all types of respirometric tests, such as OECD biodegradability tests, soil respiration, biogas testing and much more. The data obtained can be further processed electronically. The current five types of heads are:

Respirometric BOD System OxiTop®-i

OxiTop®-IDS Set 6: BOD Self Check and aerobic degradation

OxiTop-IDS AN 6 Measuring System for Anaerobic Degradation (H2S resistant pressure sensors)

OxiTop-i is the perfect system for respirometric self-check BOD between 1 and 7 days in municipal wastewater treatment plants. Menu-guided with direct display of BOD in mg/l.

Up-to-date BOD Measurement

The new Respirometric  OxiTop®-i is a modern easy-to-use instrument for BOD measurement (Biochemical Oxygen Demand).  This measuring system for BOD self checks measurement with undiluted samples (DIN EN 1899 -2) - measuring ranges up to 4,000 mg/l BOD possible. Measurement can be done over one to seven days. The sample volume to test can be selected in the menu, the subsequent conversion into the corresponding BOD value will be automatic, error-free and convenient. A small LED provides inform on the actual operating condition of the head.
