BODTrak-II-生化需氧量分析仪-(1)

BODTrak II Biochemical Oxygen Demand Analyzer

-Working principle: BODTrak®II Biochemical Oxygen Demand Analyzer uses the differential pressure measurement principle to simulate the process of microbial degradation of organic matter in nature: the oxygen in the air above the test bottle continuously replenishes the dissolved oxygen consumed in the water, and the generated CO2 is sealed in the cover The potassium hydroxide absorbs, and the pressure sensor can monitor the change of oxygen pressure in the sampling test bottle at any time. Therefore, through the relationship between the BOD (corresponding to the amount of oxygen consumed in the test bottle) and the gas pressure, the BOD measurement can be accurately performed, and the test results are directly displayed on the screen as a graph. -Application industry: B

Product description
Technical indicators
- working principle:
 
The BODTrak® II Biochemical Oxygen Demand Analyzer uses the differential pressure measurement principle to simulate the process of natural microorganisms degrading organic matter: the oxygen in the air above the test bottle continuously replenishes the dissolved oxygen consumed in the water, and the resulting CO2 is potassium hydroxide in the sealed cover Absorption, and the pressure sensor can monitor the change of oxygen pressure in the sampling test bottle at any time. Therefore, through the relationship between the BOD (corresponding to the amount of oxygen consumed in the test bottle) and the gas pressure, the BOD measurement can be accurately performed, and the test results are directly displayed on the screen as a graph.
 
-Application industry:
 
BOD measuring instrument is widely used in municipal sewage, industrial sewage, environmental monitoring, university research, domestic sewage, agriculture and other industries.
 
-Instrument features and advantages:
 
● The pressure difference method is adopted, which is in accordance with the national standard method. Simulate the process of microbial degradation of organic matter in nature, closer to the real situation
 
● The BOD tester can continuously read and display the changes of the measurement process in real time with graphics
 
● Has 6 independent measurement channels
 
● With automatic shutdown, automatic data collection functions
 
● The BOD tester can not only read the measurement results directly from the graph, but also observe the cultivation and reaction process through the curve, making the test results more intuitive
 
-There are pointers in the graphics
 
-Graphic display of BOD values ​​and cultivation time
 
● Compared with the dilution inoculation method, the operation is simpler and more convenient
