BOD detector

a

Product Introduction:

The BOD detector is based on the 5-day cultivation method of the national standard “HJ505-2009”, simulating the biodegradation process of organic matter in nature, and adopts a simple, safe and reliable mercury-free differential pressure sensing method to measure BOD in water; fully intelligent design, leading R&D process and design and manufacturing, the experimental process does not require laboratory personnel on duty; it is suitable for biochemical oxygen demand determination in sewage discharge enterprises, environmental monitoring, sewage treatment plants, third-party testing institutions, scientific research, universities and other fields.

Product Features:

1. Android intelligent system, better interactive operation experience, simpler and faster;

2. The data of the six samples are displayed uniformly by the host, and the data can be directly compared, which is more convenient;

3. The detection head is connected to the host via Bluetooth, and the data is wirelessly transmitted to the host for display.

4. The base integrates 6 USB ports, which can be used directly to charge the detection head. A full charge can be used for more than half a year.

5. Six independent test terminals, new measurement groups can be added at any time during the test process;

6. Directly read BOD concentration value, no calculation required;

7. Mercury-free pressure difference design, high accuracy, no conversion required, and ensure the safety and health of experimenters;

8. No pipeline design in the experimental link to avoid pipeline aging, leakage and other disadvantages;

9. The measurement range can be selected. When the water sample concentration is lower than 4000g/L, no dilution is required;

10. The measuring instrument automatically records the measurement data. 60 sampling points can be selected in one test cycle, and the test data is more accurate;

11. The cultivation cycle can be adjusted and can be selected according to needs;

12. The measurement process is automatically completed without the need for special personnel on duty;

13. The large-size LCD display is intuitive and clear, and the project selection is convenient;

14. The test terminal comes with a large-capacity battery with a battery life of more than 2 years. It is not affected by short-term power outages in the external environment during the test.
