Choosing the right CO2 gas safety system for your business is no longer optional, it’s a critical requirement for protecting people, meeting fire code compliance and reducing liability in industries like food & beverage, laboratories, indoor agriculture and industrial gas operations.
With stricter enforcement of OSHA exposure limits and IFC fire code requirements, owners, operators, and facility managers are searching for reliable, easy-to-install and compliant CO2 safety monitoring systems.
To help you make the right decision, we analyzed the top systems based on:
- Code compliance (OSHA, IFC, NFPA)
- Ease of installation and maintenance
- Alarm capabilities (audible, visual, relays)
- Scalability and flexibility
- Total cost of ownership
Below are the 5 best CO2 gas safety systems in 2026, including how they compare and where each one fits.
Why CO2 as Safety Systems are Critical
The main reason that businesses and industry professionals need a gas safety monitor is because they are either using, producing, or storing CO2 gas. High levels of CO2 in enclosed areas is dangerous.
Because CO2 is:
- Colorless and odorless
- Heavier than air (accumulates in low areas)
- Capable of displacing oxygen
At elevated levels, CO2 exposure can lead to:
- Headaches and dizziness
- Confusion and rapid breathing
- Loss of consciousness
- Asphyxiation in extreme cases
As a result, many jurisdictions now require gas detection systems for:
- Beverage CO2 storage rooms
- Walk-in coolers
- Labs using incubators or cryogenics
- Indoor grow facilities
- Industrial gas fill plants
What to Look for in a CO2 Safety System
There are two different types of gas detection monitoring devices: fixed/wall-mount and portable/handheld. Both of these devices will monitor and protect workers near stored or created carbon dioxide.
Before choosing a system, ensure it includes:
- Multi-level alarms (5,000ppm / 30,000ppm thresholds)
- Audible and visual alarms
- Relay outputs for ventilation, valve shutoff, BMS integration
- Code compliance support
- Ease of installation and calibration
This article compares fixed/wall-mount gas safety monitors for restaurants, breweries, beverage dispensing areas, cultivation facilities, industrial applications and safety industries.

2. Analox AX60+ (Best for Multi-Gas Flexibility)
The Analox Ax60+ is a popular CO2 safety monitor used by many restaurants and sports bars due to its flexibility across environments.
This device is created primarily for CO2 monitoring. However, it can connect additional sensors to include O2 monitoring dependent upon customer use case. Another feature is the audible and visual indicators when the alarm setting is triggered providing safety indication and indicating if gas concentrations are at hazardous levels.
In addition to its ability to meet safety standards and setpoints this device also allows for multiple sensors.
Pros
- Supports CO2 and O2 sensors
- Scalable for multiple environments
- Reliable compliance performance
Cons
- More complex installation
- Smaller display and less intuitive interface
- No environmental readings (temp/RH)
Best For
- Labs and industrial environments
- Facilities needing multi-gas flexibility
The base Ax60+ cost $795.
3. LogiCO2 Mk9 System (Best for Legacy Systems)
Third on our list, is the LogiCO2 CO2 Mk9 Detector. This device is reputable across the industry due to its longevity in the market and multiple language options.
Although at a higher price point, the LogiCO2 CO2 Mk9 does come with a main sensor unit, display, and horn strobe.
Pros
- Proven system with long industry track record
- Includes sensor, display, and horn/strobe
- Multi-language support

4. PureAire Gas Safety Monitor
Fourth on our CO2/O2 Safety Monitor list is the PureAire CO2/O2 Monitor.
This device is another common solution for restaurants, beverage industries, or anyone working near hazardous gas in confined spaces. The PureAire CO2 monitor is a good choice specifically for those looking to monitor dual gases as it can measure both CO2 and O2. In addition, the monitor also has user-configurable relays that can be sent for different use cases or applications.
The PureAire CO2/O2 monitor cost is $2,095.
5. Macurco Fixed Gas Detection (Best for Budget Applications)
Macurco provides the CD-6B fixed gas detection system commonly used in commercial and light industrial settings.

Do I need a Gas Safety Meter?
According to the Occupational Safety and Health Administration (OSHA), there is a set of standards for anyone using, producing, or storing gas. For example, the standard states that a gas safety monitor must be used to protect employees, customers, and establishments. It also notes specifically that a gas safety monitor must comply with the standards by measuring up to 5,000ppm over a 8-hour time weighted average (TWA).
While many industries use carbon dioxide to maximize plant yields or create delicious carbonated beverages; understanding the severity of a potential gas leak and having monitors in place can be life-saving.
Here are a few examples of why a gas safety monitor should be installed.
For those establishments that believe they can get away with not having a gas safety monitor installed, the result can be fatal.
When compressed gas is confined to a small space and a potential leak occurs or individuals experience exposure, the gas displaces the air. When this happens, overexposure to those in the area can lead to severe health conditions such as:
- Fatigue
- Headache
- Drowsiness
- Rapid breathing
- Confusion
- Increased heart rate
- Unconsciousness
At higher levels, compressed gases can lead to even more sever symptoms such as loss of vision, asphyxiation and fatality at high levels of 100,000ppm or greater.
Today, municipalities now require facilities to have gas safety monitors in place and installed for anyone storing, producing, or using gas; as well as those using bulk gas systems.
We hope you found this guide both informative and useful in your gas safety monitor search and if you have any additional questions we would be happy to assist you in your set-up.
For more information on gas safety resources we recommend the following:
- Employee Safety Training: all employees should be properly trained on preventative measures, safety procedures, and symptoms of exposure on an annual or quarterly basis (for both new and existing personnel).
- Warning Signage: CO2Meter makes it a point to ensure that all customers understand that proper warning signage does come included with majority of our safety devices. You need to ensure that you have the proper signage to place around gas sources or areas where employees could potentially be exposed.
- Ventilation: Many of the gas safety monitors have the capability to trigger an exhaust fan or control panel. It is critical to make sure your facility has a standard ventilation system in place that will vent hazardous gas from the area.
