Functional characteristics:
 
1. The determination principle adopts microbial electrode method, which is more convenient and faster than traditional BOD5;
 
2. The continuous constant current micro-injection method is adopted, the sample collection amount is small, no pretreatment reagents are added, and the secondary emission is zero pollution;
 
3. The operation and maintenance are simple and convenient, and the modular structure design is convenient for maintenance;
 
4. Water samples do not need pretreatment and have strong anti-interference ability;
 
5. High safety, non-toxic and harmless solidified diaphragm microbial sensor, convenient activation and use;
 
6. Reliable structure, simple without wearing parts and long service life;
 
7. Polarographic three electrodes, integrated detection and circulation, stable and reliable signals;
 
8. The constant temperature system adopts PIO constant temperature controller independently developed to form a precise but stable test temperature field.
