BOD measuring system OxiTop®-IDS IS for determination of aerobic degradation, Extension set for OxiTop®-IDS Set 6/12
These tests quantify the biological degradability of chemicals.With the proven Bluetooth® connectivity and the convenient operation via MultiLine® multi parameter instrument Multi 3620 IDS or Multi 3630 IDS. Using a Multi 3620 IDS or Multi 3630 IDS in BOD special mode the BOD measuring range extends to 400000 mg/l. For an already existing Multi 3620 or 3630 IDS, a firmware update is sufficient. Herewith beneath the OxiTop® applications also measurement of pH, conductivity, solved oxygen and turbidity are available. All heads can be used independently for routine BOD measurements from 1 to 7 days.Respirometric degradability tests according to OECD 301F/DIN EN ISO 9408Versatile measurement by using the BOD special modeMeasurement duration selectable (0.5 hours to 180 days)Bluetooth® connectivityDirect calculation of all results in the meterRepresentation of curves for monitoringParallel measurement of different examinations and methodsExport to data acquisition programsPlease order CO2 absorber NHP 600 (9.303 403) separately.The IDS multi parameter measuring instruments Multi 3620 IDS Set WL or Multi 3630 IDS Set WL are required.

BOD-Measurement-System BD 600
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.Scope of supply:BD 600, complete unit with 6 or 12* sensor heads and control unit with batteriesPower supply unit incl.
