WTW's OxiTop IS6: a high-performance solution for BOD measurement
The WTW OxiTop IS6 is a laboratory instrument specially designed for respirometric measurement of biochemical oxygen demand (BOD) in water samples. Its design combines ergonomics and precision to facilitate the work of operators in environmental, industrial or drinking water and wastewater quality control analyses. Each measuring head is equipped with a backlit LCD graphic display, showing the BOD value and progress curve in real time, providing a clear view of the data throughout the process.
This system has six measuring units, allowing several samples to be analysed simultaneously. Thanks to an intuitive menu, it is possible to set the measurement duration between 1 and 7 days and the exact volume of the sample to be analysed, ensuring automatic and error-free conversion to BOD values.
Technology optimised for accuracy and reliability
The OxiTop IS6 works on the principle of respirometric measurement, using the pressure variation in a closed system to calculate the oxygen consumption of the microorganisms present in the sample. The measuring range extends from 0 to 4000 mg/L, covering a wide range of analytical needs.
A multi-coloured LED indicator shows the operating status of each unit, simplifying process monitoring. In addition, the system allows intermediate measurement intervals to be viewed without interrupting the current analysis, optimising data management.
The device is designed to minimise human error, in particular thanks to the direct entry of the sample volume in the menu, avoiding any manual conversion. The results are reliable, reproducible and comply with the requirements of control laboratories.
Ergonomics and versatile applications
Thanks to its modular design and user-friendly features, the OxiTop IS6 is suitable for a wide range of applications: industrial effluent monitoring, wastewater treatment plant monitoring, assessment of organic pollution in surface water, and teaching and training in environmental sciences.
The measuring heads are colour-coded for easy differentiation between incoming and outgoing samples. The device can be supplemented with various accessories such as programmable inductive stirring platforms, measuring bottles with overflow and specific consumables such as CO₂ absorber or nitrification inhibitor.
Robust and reliable, the OxiTop IS6 is an essential tool for laboratories seeking to combine precision, ease of use and the ability to process multiple samples simultaneously.
