Introduction: It is designed and developed according to the standard of "HJ/T86-2002 Rapid Determination of Biochemical Oxygen Demand (BOD) of Water Quality Microbial Sensors" issued by the State Environmental Protection Administration. It is suitable for surface water, domestic sewage and industries that do not contain obvious toxic effects on microorganisms. Determination of BOD in wastewater; Features: 1. The measurement principle adopts the microbial electrode method, which is more convenient and faster than the traditional BOD5; 2. The continuous constant flow micro-injection method is adopted, the sample collection volume is small, no pretreatment reagent is added, and the secondary emission is zero pollution; 3. Simple and convenient operation and maintenance, modular structure design, easy maintenance; 4. The water sample does not need pretreatment, and has strong anti-interference ability; 5. High safety, non-toxic and harmless curing diaphragm microbial sensor, easy to activate and use; 6. Reliable structure, simple and no wearing parts, long life; 7. Polarographic three-electrode, integrated detection and circulation, stable and reliable signal; 8. The constant temperature system adopts the independently developed PIO constant temperature controller to form a precise but stable test temperature field. Technical parameter: Host parameters 1.
