Brief introduction:
The instrument design, according to the principle of differential pressure measurement instrument to simulate the process of organic matter degradation in nature: test the bottle in the air above 21% of the consumption of oxygen, constantly replenish water, dissolved oxygen in the process of organic matter degradation of CO2 absorbed by sealing cover of sodium hydroxide and the change of the pressure sensors constantly monitor the sample bottle. Biochemical oxygen demand (cod) BOD (i.e., corresponding to the test in a bottle of oxygen consumption) and establish a correlation between gas pressure, through the instrument to deal with this correlation, then directly on the instrument screen showing the biochemical oxygen demand (cod) BOD values. Features:
1. The BOD trend curve display
2. With the function of print output
3. Can be connected through the USB interface with the computer
4. Mercury-free device to ensure safety of BOD measurement accurately
5. Real-time clock display
6. Automatic data acquisition and storage
7. Describe BOD process curve for the user to see
8. Can connect the computer to print process curve
9. The system parameter and the experimental data is not lost when power supply drop
10. The LCD interface, according to the humanized operation more easy to understand Technical parameters:
The measurement accuracy: + / - 1% (F.S.)
