Background:
CO sensor play an important role in civil, industrial and atmospheric environment detection and other fields. In daily applications, the most are electrochemical carbon monoxide sensors.
Civil field:
In the civil field, CO sensor are often used in household carbon monoxide alarms and household gas water heaters. It detects carbon monoxide concentration in real time to prevent carbon monoxide poisoning accidents.
One of the most common is the use of electrochemical carbon monoxide sensors.
The target gas reacts in proportion to its concentration and follows Faraday’s law. Measuring the current can indicate the concentration of the gas.
Carbon monoxide electrochemical gas sensor has low power consumption, high precision, high sensitivity, wide linear range and strong anti-interference ability.
It has excellent repeatability and stability and is very suitable for carbon monoxide detection in civil field.
Industry:
In petroleum, metallurgy, mining and other industrial fields can not lack of carbon monoxide concentration measurement.
When the electrochemical carbon monoxide sensor is used, CO and O2 have corresponding REDOX reactions on the working electrode. And the opposite electrode respectively and release charge to form a current. The current generated is proportional to the concentration of CO. The test current reflects the concentration of carbon monoxide.
The low power consumption, high precision, high sensitivity and wide linear range of CO sensors are very suitable for the determination of carbon monoxide concentration in the industrial field.
Field of atmospheric environment testing:
However, carbon monoxide is also an air pollutant, one of the most abundant and widely distributed in the atmosphere. Then it is the product of incomplete combustion of carbon-containing materials such as coal and oil.
High carbon monoxide content in the air not only makes the air quality worse, but also affects people’s health, causing acute and chronic poisoning, and even death.
As a result, carbon monoxide electrochemical gas sensor is also suitable for urban atmospheric environment monitoring, enterprise environmental monitoring, factory area unorganized discharge pollution gas monitoring, emergency monitoring environmental evaluation monitoring.
