This document introduces a portable BOD rapid analyzer, which measures BOD value using the microbial electrode method. It has the characteristics of fast and accurate measurement. The instrument has been approved by the National Environmental Protection Agency and complies with the industry standard (HJ/T86-2002). The sensor adopts a three-electrode integrated core sensor with a reference electrode. The microbial membrane is a sandwich dry membrane with a long lifespan. The instrument is suitable for on-site monitoring, with a constant speed continuous sampling method and a reflector-type constant temperature tank with high temperature control accuracy.
This manual provides operating instructions for Techno's portable biochemical oxygen demand (BOD) measurement instrument. It describes the sensor features, measurement principle, and usage modes for on‑site monitoring.
Key sections cover device specifications, sample handling, power options, data storage, and maintenance procedures, enabling users to perform accurate BOD5 analysis in the field. This manual is written in Chinese.
