Differential pressure BOD analyzer

1、 Product Introduction:

　　Pressure difference methodBOD analyzerIt refers to the national standard "HJ505-2009" 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, R&D process 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.

IIPressure difference methodBOD analyzerProduct features:

1. The Android system provides a better interactive experience and is more convenient and efficient;

2. 7-inch LCD touch screen, convenient operation interface, all numerical comparison display, convenient and intuitive;

3. The mercury free pressure difference method used has no mercury pollution and accurate and reliable data;

4. ★ 6 testing terminals, independently controlled, and can add new measurement groups at any time during the testing process;

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

6. 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;

7. 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;

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. It can be fully charged and used for more than six months.

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, making the detection data more accurate;

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 clock system, real-time display of time, and the ability to query measurement data by time;

17. The instrument is equipped with a cloud platform that allows for wireless upload of detection data via WIFI. After logging in on a computer or mobile phone, the data can be viewed, analyzed, and statistically 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.
