Description
Instrument Introduction
Designed and developed according to the standard HJ/T86-2002 "Biochemical Oxygen Demand (BOD) Determination of Water Quality Microbial Sensor Rapid Determination Method" 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 determination principle adopts the microbial electrode method, which is more convenient and faster than the traditional BOD5;
2) The continuous constant flow micro-sampling method is adopted, the sample collection volume is small, no pretreatment reagent is added, and the secondary discharge is zero pollution;
3) Simple and convenient operation and maintenance, modular structure design, easy to maintain;
4) The water sample does not require pre-treatment and has strong anti-interference ability;
5) High safety, non-toxic and harmless solidified diaphragm microbial sensor, easy to activate and use;
6) Reliable structure, simple and no wearing parts, long life;
7) The detection and circulation are integrated, and the signal is stable;
8) The constant temperature system adopts the independently developed P10 constant temperature controller to form an accurate and stable test field.
