Five day biochemical oxygen demand determination and analysis using BOD detector

Instrument DescriptionThe QH-101 BOD analyzer is based on the national standard "HJ505-2009 Determination of Five day Biochemical Oxygen Demand (BOD5) for Water Quality"According to the "Interpretation and Vaccination Law", simulating the biodegradation process of organic matter in nature, using simple, safe, and reliable mercury free methodsDifferential sensing method is used to measure the BOD value of water quality. The instrument adopts intelligent measurement and control technology, and the entire measurement process is controlled and checked through a mobile appLook, wireless data transmission can achieve automatic reconnection matching of multiple devices, making it convenient to view real-time measurement data results. Widely applicableSuitable for environmental monitoring stations, third-party testing institutions, scientific research, universities, and sewage discharge enterprises.

Main functional features

1. Wireless data transmission, mobile app control, and graphic display throughout the entire operation process;

2. Industrial appearance mold design, compact overall size,;

3. Adopting sensing technology to effectively avoid the influence of external atmospheric pressure changes on measurement results;

4. Mercury free differential pressure measurement method ensures the safety of experimental operators and accurate measurement results;

5. Each culture bottle is measured independently, and the start and stop of a single measurement can be set arbitrarily. The culture bottles do not interfere with each other;

6. The number of measuring heads can be freely selected and ordered, and additional measuring heads can be purchased independently in the future;

7. The measurement process is guided throughout the entire process, making it easy for personnel without professional knowledge to quickly get started;

8. Real time viewing of measurement and historical data through a mobile app, with clear data and curves at a glance;

9. The measurement history data is easy to save, and the data supports automatic upload to email backup. It can also be divided into measurement data through mobile phonesEnjoy;

10. One charge can achieve continuous and uninterrupted measurement for more than 30 days;

11. Electromagnetic stirring system, freely matched, stable operation, and long service life.
