- Commodity name: YP-BOD5A series biochemical oxygen demand meter
instrument
YP-BOD5A biochemical oxygen demand meter is based on the national standard "HJ505-2009" 5-day culture method, simulating the biological degradation process of organic matter in nature, using a simple, safe and reliable mercury-free differential pressure sensing method to measure BOD in water. Intelligent design, research and development process and design. It can accurately provide the determination results comparable to the chemical dilution method, has the characteristics of intuitive reading, clear biochemical reaction curve and convenient use and maintenance, and the experimental process does not need the experimental personnel to be on duty. It is suitable for BOD determination in sewage enterprises, environmental monitoring, sewage treatment plants, third-party testing institutions, scientific research, universities and other fields.

working principle
biochemical oxygen demand (BOD) is defined as the amount of dissolved oxygen consumed by aerobic microorganisms in water. when the sample is placed in an incubator, the culture temperature is 20 ℃, and the culture is carried out for five days, the content of dissolved oxygen consumed is measured to determine the BOD value of the water sample.
biochemical oxygen demand refers to the amount of dissolved oxygen consumed or required to decompose organic matter in water through the reproduction and respiration of aerobic microorganisms in water under specific conditions. The BOD value in water is usually expressed by the amount of dissolved oxygen (mg/L) consumed by the sample at 20°C for 5 days, and is recorded as "BOD".
Main technical index
1, measurement range: 0~4000 mg/L(BOD value needs to be diluted when exceeding the measurement range)
2, simultaneous determination of sample number: 6 samples
3 each time, accuracy: comply with the national standard "GB7488-87" (BOD value of glucose glutamic acid standard solution is in the range of 180 mg/L ~ 230 mg/L)
4. Display: LCD display circularly displays BOD value and biochemical reaction curve of each sample.
5, culture temperature: 20 ℃ 1 ℃
6, power supply: AC 220V 22V 50Hz 0.5Hz
7, power consumption: instrument ≤ 50W, constant temperature box ≤ 300W
8, instrument can save BOD value and biochemical reaction curve of six samples analyzed last time.
