Electrochemical CO Sensor 4S-CO
Summary:
The electrochemical 4S-CO carbon monoxide gas sensor works according to the principle of electrochemistry, using the electrochemical oxidation process of the gas to be measured at the working electrode potential in the electrolytic cell, and the current generated by the electrochemical reaction of the gas to be measured is proportional to its concentration and follows Faraday According to the law, the concentration of the gas to be measured can be determined by measuring the magnitude of the current.
Feature:
* Low power consumption
* High precision and sensitivity
* Wide linear range
* Strong anti-interference ability
* Excellent repeatability and stability
APPLICATION
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.
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.
Common toxic and harmful gases can be divided into irritating gases and asphyxiating gases according to their toxic properties.
Industrial waste gas refers to the general term for various pollutant-containing gases discharged into the air generated during the fuel combustion and production process in the factory area of the enterprise. These gases enter the human body through the respiratory tract through different routes, some directly cause harm, and some have an accumulation effect, which will seriously endanger human health.
