What Is the MNS-4CO-1000 CO Sensor?
The MNS-4CO-1000 is a three-electrode electrochemical sensor specifically designed to detect carbon monoxide, commonly abbreviated as CO.
Carbon monoxide is a colorless and odorless toxic gas that may be produced by incomplete combustion. CO monitoring is widely used in industrial safety equipment, combustion systems, parking facilities, boiler rooms, generators and portable gas detection devices.
The MNS-4CO-1000 converts the electrochemical reaction caused by carbon monoxide into a small electrical current. This output current changes in proportion to the CO concentration and can be processed by an external analog front-end circuit to calculate the gas concentration.
How Does an Electrochemical CO Sensor Work?
The MNS-4CO-1000 uses a three-electrode electrochemical structure consisting of a working electrode, reference electrode and counter electrode.
When carbon monoxide enters the sensor through the gas-permeable membrane, CO molecules reach the working electrode and participate in an electrochemical reaction.
This reaction produces an electrical current related to the amount of carbon monoxide present.
The reference electrode helps maintain a stable electrochemical potential, while the counter electrode completes the reaction inside the sensor.
The resulting current signal is amplified and processed by the host electronics to generate a CO concentration reading.
This electrochemical sensing principle provides a combination of compact size, low power requirements and sensitive CO measurement, making it suitable for portable and fixed gas detectors.
