ME2-CO 14*14 Carbon Monoxide Electrochemical Gas Sensor Harmful Gas Concentration Detection Probe

                 ME2-CO 14*14 Carbon Monoxide Electrochemical Gas Sensor Harmful Gas Concentration Detection Probe

Working Principle:

It is a fuel cell - type sensor that operates based on the electrochemical principle. Carbon monoxide and oxygen undergo corresponding redox reactions on the working electrode and the counter electrode inside the electrolytic cell, which releases electric charges to form an electric current. The magnitude of the generated current is proportional to the concentration of carbon monoxide and complies with Faraday's Law. Thus, the concentration of carbon monoxide can be determined by measuring the current value.

Applications:

The sensor is widely applicable in commercial and especially civilian fields for carbon monoxide concentration detection. It is a core component of various carbon monoxide detectors and CO alarms. These devices are commonly installed in homes, small - scale commercial places like small restaurants, and other indoor environments where coal - burning, gas - burning appliances or heating equipment are used, to promptly alert people to potential CO poisoning risks.

Core Features:

1. Low Power Consumption: It is designed with low power requirements, making it suitable for various battery - powered portable CO detectors and household fixed - type alarm devices, which helps extend the battery life of the equipment.
2. High Performance in Accuracy and Sensitivity: It has a sensitivity of up to 3.6 - 9 nA/ppm and a resolution of 1 ppm. This high sensitivity and accuracy enable it to capture even slight changes in carbon monoxide concentration and output precise detection results.
3. Excellent Stability and Repeatability: The repeatability error of the sensor is less than 3% of the output value, and its annual stability drift is less than 10%. Meanwhile, the zero drift is no more than 10 ppm within the temperature range of -20℃ - 40℃, ensuring consistent and reliable performance during long - term use.
4. Strong Anti - Interference Capability: It is resistant to water vapor interference and will not be poisoned. It can minimize the impact of irrelevant factors in the ambient environment on the detection results, ensuring the authenticity of CO concentration data.
5. Broad Environmental Adaptability: It can work stably in most common indoor and general commercial environments, adapting to fluctuations in temperature and humidity within a certain range.
