1、 Product Introduction:

HD-BOD5 型Biochemical Oxygen Demand (BOD) MeterAccording to the national standard HJ505-2009, the 5-day cultivation method simulates the biodegradation process of organic matter in nature, and uses a simple, safe, and reliable mercury free differential pressure sensing method to measure the concentration of BOD in water; Fully intelligent design, leading R&D technology and design manufacturing, no need for laboratory personnel to be on duty during the experimental process; Suitable for biochemical oxygen demand measurement in the fields of polluting enterprises, environmental monitoring, sewage treatment plants, third-party testing institutions, scientific research, universities, etc.

2、 Product features:

1. Adopting internationally advanced mercury free differential pressure method, with no mercury pollution and accurate and reliable data;

2. 6 testing terminals, independently controlled, and capable of adding new measurement groups at any time during the testing process;

3、Android 智能系统，操作交互性体验更好，更加简便快捷；

4. 7-inch LCD touch screen, user-friendly human-machine interaction design, all numerical comparison display, simple and intuitive;

5. No manual conversion is required, the instrument can directly display BOD concentration values, and multiple sets of data can be displayed on a unified interface;

6. The instrument can automatically analyze and draw the data curve of the measured water sample, and multiple sets of curves can be displayed on a unified interface;

7. The test terminal is connected to the host via Bluetooth and wirelessly transmits data to the host for display.

8. Each testing terminal is equipped with a large capacity lithium battery with a lifespan of over 2 years, and a brief power outage has no impact on the testing;

9. The base integrates 6 USB ports, which can be directly used to charge the testing terminal, and can be used for more than six months when fully charged.

10. There is no pipeline design in the experimental stage to avoid drawbacks such as pipeline aging and air leakage;

11. The measurement range can be selected, and no dilution is required when the water sample concentration is below 4000g/L;

12. The measuring instrument automatically records measurement data, and the time recording frequency can be set arbitrarily for more accurate detection data;

13. The cultivation time can be flexibly adjusted according to needs, up to a maximum of 30 days;

14. Automatically complete the measurement process without the need for dedicated personnel to be on duty;

15. Built in thermal printer, which can automatically print the parameters set before measurement, and can freely cancel the content that does not need to be printed;

16. Built in real-time clock system, with real-time clock display and the ability to query measurement data by time;

17. The instrument is equipped with a cloud platform, which allows for wireless upload of detection data through WIFI or hotspot. After logging in on a computer or mobile phone, the data can be viewed, counted, and analyzed more clearly.

18. The instrument is equipped with a demonstration video of the operation steps. Users can watch the video inside the instrument to learn and get started more quickly.
