Products are widely used in environmental protection, water quality monitoring, agriculture, forestry soil, teaching and research departments. 
 BOD tester using a simple sample dilution, the BOD measurement is easy, no transport control facilities. The operator simply adding the sample and the measurement of BOD nutrient buffer to make six BOD bottle, the bottle is connected to the microprocessor control device pressure sensor, range from four to select a suitable range, BOD test device can be completed after the test. When the sample temperature stabilized, the device began to read out and stored in the BOD value of the instrument's memory, every 15 minutes of recording time. 

 Characteristics of the test device 1. No mercury devices to ensure accurate measurement of BOD 
 2. Automatically collect and store data 
 3. Convenient buttons interface 
 4. Just a button you can print directly shown in Figure 
 5. Through the RS-232 input and output interfaces 
 6. Independent channels feature sixteen samples were obtained from the parameters 
 Graphical display continuously updated results and status BOD 
 8. Electromagnetic stirrer to ensure continuous stirring continuously added to the sample in oxygen 
 9. Sample dilution is easy, you can measure the high range of BOD
