1、Measuring range：0～1000 mg/L（when the BOD₅ value exceeds the measuring range, it needs to be diluted）

2、Simultaneous determination of the number of samples: 6 samples or 8 samples each time

3、Accuracy: in line with the national standard "GB7488-87"

（The BOD₅ value of the standard solution of glucose and glutamic acid is in the range of 180 mg/L to 230 mg/L）

4、Display: The LCD display cyclically displays the BOD₅ value and biochemical reaction curve of each sample.

5、Culture temperature：20℃±1℃

6、Power supply：AC 220V±22V    50Hz±0.5Hz

7、Power consumption：Instrument≤50Ｗ，Incubator≤300Ｗ

8 、The instrument can save the  BOD₅ values and biochemical reaction curves of the eight samples analyzed last time
