BOD Measurement with direct sample selection and interface

The Lovibond® BOD-OxiDirect sensor system from Tintometer (Germany) for permits exact and convenient measurement of the Biochemical Oxygen Demand (BOD) based on the respirometric principle. All results are shown in a big display directly in mg/l BOD without the need for time-consuming conversion using factors. In addition, the measur-ing period can be user-selected between 1 and 28 days.
The unit measures BOD levels via the pressure drop in the closed system during a de-fined period of time. Following measurement, the results are stored and can be called up to the display at any time. The inductive stirrer system not only mixes the sample but also ensures optimum gas exchange between sample and gas space in the sample flask. Alongside the BOD unit to determine BOD levels, a BOD system contains sample flasks, a non-wearing inductive stirrer system, overflow measuring flask to measure the sample volume, nitrification inhibitor and potassium hydroxide as an absorbent.
