Carbon Monoxide Detection: CO sensor


Carbon Monoxide is is a chemical compound which consists of one carbon atom and one oxygen atom. It is a colourless, odourless and flammable gas at room temperature, and can be detected using a CO sensor.

What is Carbon Monoxide?

When carbon monoxide is encountered in concentrations of over 35 ppm it is toxic to humans and animals that use haemoglobin as an oxygen carrier. Carbon monoxide causes harm by combining with haemoglobin to form carboxyhaemoglobin, which prevents the blood from carrying oxygen.

CO is produced during the incomplete burning of organic matter. This can occur from motor vehicles, heaters, or cooking equipment that run on carbon-based fuels. It can also occur from exposure to methylene chloride. Therefore, Carbon monoxide is spatially variable and short lived in the atmosphere, where it has a role in forming ozone at a ground level.

Why is Carbon Monoxide Detection essential?

A Carbon Monoxide monitor is essential for CO detection for a number of reasons. Primarily because it detects the presence of CO which can prevent carbon monoxide poisoning. The gas is tasteless, odourless, and colourless, and therefore it cannot be detected by vision or smell, which makes a CO sensor vital.

Carbon monoxide poisoning is the result of breathing in excessive levels of CO. It can cause loss of consciousness, seizures or even death. It is quite common as it results in more than 20,000 emergency department visits in the US and is the most common type of fatal poisoning in many countries.

Applications for a Carbon Monoxide Monitor

Carbon monoxide detection using a CO sensor takes place across a number of different applications. Below is a list of just a few with links to their application notes on our website.

Our CO Sensors for Carbon Monoxide Detection:

When it occurs in high concentrations, such as when it is used in heat treatment furnaces, carbon monoxide detection can take place using non-dispersive infra-red technology.

Edinburgh Sensors have been providing Gas Monitors based upon infrared sensor technology for many years. Below is a list of our Carbon Monoxide monitors which can be used for reliable and accurate Carbon Monoxide detection and measurement.
