MODEL 9880 Biological Comprehensive Toxicity Monitor

summary

Through microorganisms (with electrochemical activity) in the sensor, cytochrome generates charges and accumulates on the electrode surface. Due to the change in charges, an electric current is generated between the positive and negative electrodes of the sensor. When toxic substances flow in, the activity of microorganisms is inhibited, the charge generated by cytochromes decreases, and the sensor current changes. Based on the decrease in the peak current, it is determined whether toxic substances have flowed in.
