Carbon dioxide sensors have an important role in industrial, agricultural and atmospheric environmental testing. In daily applications, electrochemical carbon monoxide sensors are the most applications.

Domestic carbon dioxide detection

sensors are mainly widely used in home carbon monoxide alarm and household water heaters to detect carbon monoxide concentrations in real time to prevent carbon monoxide poisoning.

Electrochemical carbon monoxide sensor uses the electrochemical oxidation process of carbon dioxide gas in the electrode potential in electrolytic battles. The current generated by the gas electrochemical reaction to be measured is proportional to its concentration and follows the law of Faraday.By determining the current, the concentration of the gas to be measured can be determined.

This type of sensor has low power consumption, high accuracy, high sensitivity, wide linear range, and strong anti -interference ability. It has excellent repetitiveness and stability, which is very suitable for carbon monoxide detection in the domestic field.

Industrial carbon dioxide detection

Carbon monoxide is colorless, odorless, odorless, difficulty in water. At room temperature, carbon monoxide does not react with acid, alkali and other reactions. However, mixing with air can form explosive mixtures. In the case of bright fire and high temperature, it can cause combustion and explosion, which is flammable and explosive gases.

Carbon monoxide concentrations are required in industrial places such as petroleum petrochemicals, metallurgy, and mines. When the constant potential electrolysis type CO sensor is used, the CO and O2 respectively occur oxidation reaction on the working electrode and the corresponding electrode and release the charge to form a current. By testing the current, the level of CO concentration can be determined.

This type of sensor has low power consumption, high precision, high sensitivity, and linear range of sensors are very suitable for measuring carbon dioxide concentrations in the industrial field.

Carbon dioxide detection at the atmospheric environment

Carbon monoxide is a kind of air pollutant. It has the largest number in the atmosphere and the widest distribution. It is the product of incomplete burning of carbon -containing substances such as coal and oil. If the carbon monoxide concentration in the air is too high, which not only makes the air quality worse, but also affects people’s health, causing acute and chronic poisoning, and even death.

Constant potential electrolysis type CO sensor is also applicable to urban atmospheric environment monitoring, corporate environmental monitoring, factory emission pollution gas monitoring, and emergency monitoring environmental evaluation monitoring
