Introduction: The biochemical oxygen demand BOD5 is a must-test item for water quality evaluation and an important quality indicator for measuring water pollution caused by organic matter. The TDR-50Z BOD5 analyzer is a new type of instrument that uses the air pressure difference method to determine the biochemical oxygen demand. It can accurately provide the measurement results comparable to the chemical dilution method. It has the characteristics of intuitive readings, clear biochemical reaction curves, and convenient use and maintenance. , Is an ideal tool for job analysis. It can be widely used in environmental monitoring, petrochemical, medical and health, teaching and research departments to monitor water quality. Detection principle: Biochemical oxygen demand (BOD5) is defined as the amount of dissolved oxygen consumed by aerobic microorganisms in the water. When the sample is placed in an incubator at a culture temperature of 20°C for five days, the content of dissolved oxygen consumed is determined to determine the water Kind of BOD value. Features 1. Imported pressure sensing components to ensure data accuracy; 2. The instrument has a built-in intelligent algorithm and direct reading of concentration; 3. With automatic temperature compensation function, after the sample temperature is balanced, the measurement is automatically started 4. Use mercury-free differential pressure sensing method (breathing method) to measure BOD in water, which is safe and reliable without mercury poisoning. 5. Six independent test channels, no interference between culture flasks; 6. Wide measuring range, no need to dilute to determine BOD; 0-4000mg/L. If the dilution measurement range is wider 7. All Chinese user-friendly interface design, complete functions and easy operation 8. Automatically record the measurement data, the recording frequency can be selected, and the data analysis curve is automatically drawn and saved 9. Support viewing real-time data and all historical data 10. The test data is stored reliably for 20 years. Technical parameter: Testing standard: GB7488-87 Measuring range: 0～4000 mg/L Simultaneous determination of the number of samples: 1-6 samples each time Detection principle: mercury-free differential pressure sensing method Display: Built-in intelligent algorithm in the instrument, direct reading of concentration Culture temperature: 20℃±1℃ Power supply: AC 220V±22V 50Hz±0.5Hz Size: 290×190×72mm
