Electrochemical CO Sensor ME2-CO-Ф14×5

  • Electrochemical-CO-Sensor-ME2-CO-Ф14×5.png


ME2-CO-Ф14x5, fuel cell type sensor, detects gas concentration by measuring current based on the electrochemical principle, which utilizes the electrochemical oxidation process of target gas on the working electrode inside the electrolytic cell, the current produced in electrochemical reaction of the target gas are in direct proportion with its concentration while following Faraday law, then concentration of the gas could be detected by measuring value of current. 


* Low consumption 
* High precision 
* High sensitivity 
* Wide linear range 
* Good anti-interference ability 
* Excellent repeatability and stability

Vehicle CO Detection

If you rest in a closed car while parking and idling, shortness of breath may occur over time. If you sleep with the air conditioner turned on in the cab or with a truck heater, it is easy to inhale too much carbon monoxide and cause poisoning and loss of consciousness. In severe cases, life will be lost.


CO Alarm

In daily life, coal, charcoal, and liquefied petroleum gas will produce carbon dioxide after combustion, and carbon dioxide will be reduced to CO in a poorly ventilated environment. CO is a suffocating poison gas, which is colorless, odorless, and non-irritating. If CO leaks, it cannot be discerned by the eye or nose. As we all know, poor ventilation during combustion can lead to a decrease in oxygen content, resulting in incomplete combustion and increased CO production. When the concentration of CO in the room continues to increase, people will gradually feel headache, nausea, difficulty breathing, collapse, dizziness.


Other Detector

Formaldehyde detector is an instrument for detecting formaldehyde. Generally, semiconductor sensors and electrochemical sensors are used to realize the rapid semi-quantification of formaldehyde in indoor air on the spot, which is characterized by simple structure, small size, intuitive,easy to carry and use.

CO sensor

Carbon monoxide is a toxic gas that can cause shock and other dangers to the human body. Therefore, whether it is some mine units or hospitals and schools, it is often considered to install carbon monoxide sensor equipment to prevent this gas.

How to prevent carbon monoxide poisoning?

Carbon monoxide is a colorless, odorless, non-irritating, toxic gas that cannot be sensed by the five senses. It can inhibit the oxygen-carrying capacity of the blood. When poisoned, it is often impossible to detect it by yourself, and it is already too late.

Underground parking lot CO monitoring

Carbon monoxide (CO) is a colorless, odorless and toxic gas. With the popularity of private vehicles and underground garages, poisoning incidents caused by it are also frequently seen in the newspapers. In recent years, the state has also begun to require carbon monoxide detection systems in underground garages. For example, Article 8.6.3 of the "Jiangsu Provincial Green Building Design Standards" stipulates: "Underground garages with mechanical ventilation should monitor and control the CO concentration in real time." How to detect, design and install carbon monoxide gas has never been involved in many civil construction design institutes and engineering companies.
