Fixed Vs Portable CO2 Monitors- what are they?

Carbon Dioxide (CO2) is a very clever gas which is widely used across a number of industries. However, it can also be a very dangerous gas to humans if exposed to higher levels. For more information about carbon dioxide and its dangers, read this blog post.  In order for businesses to protect their employees and customers from harmful CO2 leaks, it is recommended that they install CO2 monitors. 

 

Fixed and Portable CO2 Monitors

There are 2 types of carbon dioxide monitors available, either fixed or portable, but what are the differences? 

 

Fixed Carbon Dioxide Monitors

A fixed carbon dioxide monitor is a static monitoring system that is designed to monitor levels of CO2 in the area where it is installed, to protect those working in that location. Fixed CO2 detection systems tend to be installed in areas which store or pipe carbon dioxide gas. An effective, fixed CO2 monitor will continuously monitor CO2 levels and should have an audible and visual alarm that will alert those in the area of a dangerous leak. To increase safety measures further we recommend installing an alarm outside the room where the CO2 monitor is positioned to warn of any harmful leaks before anyone enters the environment.

The Analox Ax60+ has both an audible and visual strobe alarm in order to give early warning to take protective action such as ventilating and vacating the area. The Ax60+ fixed CO2 monitor also displays a Time Weighted Average (TWA) level which monitors over an 8 hour period meaning you can check that you are compliant with local CO2 exposure limits for a workplace. Find out more about your local CO2 exposure limit standards here. 

 

Portable Carbon Dioxide Monitors

A portable CO2 detector can also be known as a personal CO2 detector, or personal CO2 alarm and is generally a small device which can easily be worn by someone to monitor their immediate breathing zone for unsafe levels of CO2. The device is portable and stays with the user, ensuring their safety between separate rooms or locations.

Carbon dioxide is heavier than air, if there is a leak it will gather close to the ground. In order for a portable CO2 sensor to be effective, it should be kept below head height. Therefore, the lower the device is, the greater the warning time; attached to the waist on a belt, clipped to a pocket, or a lanyard is a sensible place to keep it. 

Portable_Gas_Detection

Similar to fixed monitors, portable monitors should have an audible and visual alarm to alert the person of unsafe levels to allow them time to take action such as vacating the area before exposure to the dangerous gas. 

 

Which CO2 monitor should I choose?

With a range of CO2 monitoring systems available to buy, it’s difficult to decide exactly which one you need. Many facilities choose to use both fixed and portable gas detectors in order to have maximum protection against harmful CO2 leaks. However, the suitability of which detector to choose should depend on the application, who enters the potentially dangerous area and how often it is accessed by staff and/or customers. 

Here at Analox, we offer both fixed and portable CO2 detectors for use in a variety of industries. These monitors provide flexible solutions to adapt to your application and requirements. Check out our CO2 monitoring selection here, or contact us to find out more!
