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.
Easiest calibration and verification with accurate results every time.
Measuring and monitoring turbidity is crucial for various industrial and municipalapplications, and Hach’s portable turbidimeter, the 2100Q, provides unsurpassed ease of use and accuracy. With over 80 years of experience, Hach is a leader inturbidity measurement and has consistently developed reliable and durable instruments for customers.
Refrigerated Incubators (often called B.O.D. Incubators or Low Temperature Incubators) are commonly used for applications such as B.O.D. Determinations, Plant and Insect Studies, Fermentation Studies, and Bacterial Culturing. The SHEL LAB Low Temperature Incubators have a temperature range of 20°C degrees below ambient to 45°C.
