Electrochemical CO Sensor ME2-CO-Ф14×50-C
Summary:
ME2-CO-Ф14x15-C electrochemical sensor detect 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 get by measuring value of current.
Feature:
* Low consumption
* High precision
* High sensitivity
* Wide linear range
* Good 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.
