BOD

BOD measurement is an important measurement of the effects of domestic and industrial waste water on sewage plants and outflow points. The sensor system BD 600 is a 6 sample system that allows precise measurements of BOD based on the manometric principle. Manometric respirometers relate oxygen uptake to the change in pressure caused by oxygen consumption while maintaining a constant volume. Due to the modern integral pressure sensors, it is not necessary to use mercury for the measurements. The BOD values are stored automatically in the sensor memory at regular intervals and can be called up on the large-format display at any time without the need for time-consuming conversion using factors. This means that test series that end on a Sunday can be evaluated during the following week without any problem. Measurement series can be stored on USB stick/ SD card or transferred via USB cable to evaluate the data on a computer. The measurement period is user-selectable between 1 and 28 days to suit the application. While short measurement periods are useful for scientific applications, standard BOD measurements typically extend over a period of 5 days - and manometric determination of OECD, for example, generally takes place over a period of 28 days.
