BOD Analyzer

I. Product Overview

The BOD-Q water quality analyser is a handheld single-channel device designed for rapid determination of biochemical oxygen demand (BOD) in water samples. Based on the advanced microbial coulometric principle, it can complete a measurement within a few hours and is suitable for on-site or emergency water quality monitoring. Its portability and intelligent operation make it an ideal tool for environmental monitoring and pollution incident response.

II. Applications

The handheld analyser is particularly suited to situations requiring a rapid response, such as on-site measurement where samples are difficult to preserve or transport, and emergency monitoring of pollution incidents. A lithium battery ensures normal operation in the field without mains power, greatly improving flexibility and scope of application.

III. Applicable Standards

1. T/CSUS 28-2021 Water quality — Determination of biochemical oxygen demand (BOD) — Microbial coulometric method

IV. Working Principle

The method extracts the electron flow signal from the biochemical degradation of organic matter and measures the charge in the external circuit. Through the optimised design of the microbial anode, cathode and electrolyte system, BOD can be determined rapidly and accurately; the value measured by this principle is called BOD-Q. The method greatly shortens the testing time and reduces the deviation of the results.

V. Key Features

1. Advanced principle: adopts the internationally new microbial coulometric method, ensuring accuracy and reliability.

2. Fast: results can be obtained in as little as 10 minutes, with no incubation required during sample testing, meeting the need for rapid response.

3. Simple operation: embedded system control enables intelligent measurement and reduces operating difficulty.

4. Easy to carry: small size and light weight for convenient transport and on-site use.

5. Field emergency use: a lithium battery supports operation in the field without mains power.

6. Data storage: test data can be stored and exported for subsequent analysis and records.
