Electrochemical Sensor Principle

1.Principle: Utilize the active chemical properties of the gas to be measured, which is reductive or oxidative. In the process of participating in the chemical reaction, electrons are released or absorbed. A large number of electrons form a current. The current size is proportional to the gas concentration. The concentration of the gas to be measured can be measured by measuring the current size.

2.Advantages: The performance is relatively stable. Most toxic and harmful gases can be measured by electrochemical sensors, and the measurement linearity is very good.

3.Disadvantages: Electrochemical sensors are consumables with a relatively short service life. The service life is 1-2 years in general environment, and needs to be replaced in 3-6 months in harsh environment, and the maintenance cost is relatively high.

4.Use: Mainly used for the detection of toxic and harmful gases.
