Recently, our company has launched a new IoT BOD analyzer:

QH-101W BOD analyzer, referring to the national standard HJ505-2009 Water Quality Five day Biochemical Oxygen Demand (B0D5)

According to the provisions of the "Dilution and Inoculation Method for Determination", the biodegradation process of organic matter in nature is simulated, and a simple, safe, and reliable mercury free pressure difference sensing method is used to measure the biochemical oxygen demand value of water quality. The instrument adopts cloud control IoT technology

Wireless sensing technology for network and signal can be used for measurement control, real-time and historical data query anytime and anywhere through a mobile app during the measurement process. Monitoring data is automatically uploaded and stored in the cloud without loss, and multi-point data is available

Line display, convenient for users to view the measurement process and results anytime and anywhere. It can be widely applied to environmental monitoring stations, third-party testing institutions, scientific research, universities, and sewage discharge enterprises.

Main functional features

1. The instrument adopts an industrial mold design, which is lightweight and compact in size; 2. Adopt wireless sensing technology to effectively avoid the influence of external atmospheric pressure changes on measurement results, and apply mercury free pressure

Differential measurement method ensures the safety of experimental operators and accurate measurement results; 3. Combined with the Internet of Things and digital signal technology, the measurement data transmission is fast, and the measurement process data, measurement curves, and measurement results can be viewed anytime and anywhere;

4. The instrument is equipped with a BOD interconnection system, configured with a mobile app to enable viewing of measurement data on the phone and guided operation throughout the measurement process, allowing for quick and easy access without the need for professional knowledge;

5. Record and display data and temperature hyperbolas during the measurement process, allowing real-time understanding of measurements taken under real environmental temperatures

Cheng;

6. Utilizing sleep technology and low-power circuit design, it can continuously perform measurement work for no less than 30 days, while synchronously transmitting battery power to the monitoring platform for easy control of the measurement process;

7. It can perform synchronous control of multiple sets of instruments, manage permissions, support up to 72 sets of instrument synchronous measurement operations, and process management; 8. The number of measuring bottles can be freely added and matched. Each culture bottle can be measured independently, and the measurement process can be started and the measurement results can be viewed with one click;

9. After the measurement is completed, a measurement report is automatically generated and exported to Excel, which enables the sharing, forwarding, archiving, and printing of measurement reports;

10. Measurement history records are stored in a cloud based database with large storage capacity and secure data;

11. Equipped with a magnetic stirrer, it can be used in conjunction with the culture bottle to achieve uniform stirring, stable operation, easy maintenance, and long overall service life.
