Issues regarding the installation height of carbon dioxide gas detectors
Thread Content
Dear experts, what is the recommended installation height for CO2 gas detectors? Should it be installed at 1.50 meters based on ambient gases, or at a height of 0.3m to 0.5m above the ground for toxic and harmful gases that are heavier than air?
The installation height of CO2 gas detectors is generally determined based on monitoring requirements and specific circumstances. If the purpose is to monitor changes in CO2 concentration in the air, sensors are generally installed in areas where people breathe or where CO2 tends to accumulate, such as meeting rooms and classrooms. They are usually placed at a height of around 1.2m to 1.5m, which allows for more accurate reflection of actual CO2 concentration changes. If it is intended to monitor CO2 gas leaks, it is generally installed in a location with a higher density than air, so that the CO2 gas does not settle on the ground due to its higher density, which could lead to inaccurate measurement values. At this time, it is recommended to install the CO2 gas detector at a height of 0.3m–0.5m above the ground, which allows for more sensitive detection of CO2 leaks. .
Install at a height of 0.3m–0.6m above the ground
. Consider the purpose of monitoring. If used to monitor the impact on the surrounding environment, it can be installed at a height of 1.5m at a distance of 30m ； If used for safety monitoring, it should be treated as a toxic gas and installed at a height of 0.3m to 0.5m above the ground. .
