Biochemical oxygen demand (BOD) is the amount of dissolved oxygen consumed by aerobic biological organisms to break down organic material present in a given water sample at certain temperature 20 oC over a specific time period(5 days)./p>


Respirometric BOD system is based on pressure measurement in a closed system microorganisms in the sample consume the oxygen and form CO2 ; the CO2 is absorbed by NaOH, creating a vacuum that is measured as mg/L BOD value.

BOD instrument for self-check with 2,6 or 12 measuring units, with direct display of the BOD value measuring ranges up to 4,000 mg/l BOD at the measuring head, stirring platform with universal power supply 100 to 240 VAC, 50/60 Hz; the smart head is menu-operated, with backlit graphic LCD, control LED, operating buttons, for direct BOD readings, volume pre-selection, measurement duration between 1 and 7 days selectable, display of measuring curve, display of current readings.
