當生物分解水中有機物質時它會消耗水中的氧氣並釋放出二氧化碳, 在密閉的試樣瓶中所釋放出二氧化碳藉由氫氧化鉀完全吸收之後瓶中的壓力即會造成不平衡狀態, 利用此壓力差比例計算出 BOD值. 此項極俱創新意義的技術改善了傳統測試方法的繁雜手續.

The new Lovibond® BOD-OxiDirect sensor system 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 measuring 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 defined 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.
