Why Measure CO2?

While carbon dioxide only accounts for less than 0.04% of the earth's atmosphere, it is produced, measured and controlled in dozens of industries. Here is a short example of some of them.

Indoor Air Quality

When it comes to indoor air quality, carbon dioxide is the “canary in the mineshaft”. As CO2 levels rise, the quantity of volatile organic compounds (VOCs), odors and micro-organisms in the air rise too. That’s why HVAC engineers use carbon dioxide level transmitters to regulate airflow in modern office buildings.

In addition to air quality, a carbon dioxide can also affect your health. Studies have shown high CO2 concentrations affect your ability to concentrate on tasks. If you find yourself sleepy in the office or the classroom, it may be a buildup of CO2!

Energy Savings

Carbon dioxide transmitters used in LEED certified and on-demand HVACR systems to conserve energy. Rather than continuously “dumping” conditioned air, a carbon dioxide transmitter with relay can turn on the heat, fans, or air conditioners when people enter the room, and turn them off when they leave.

Studies have shown that CO2 - based air control can result in up to 50% energy savings.

In addition, many modern buildings now use CO2 in place of toxic refrigerants to cool the air or for refrigeration, especially in grocery stores.

Beverage & Hospitality

CO2 storage safety alarms protect customers, employees and emergency first-responders near stored carbon dioxide. A leak anywhere in a stored CO2 delivery system can quickly fill an enclosed area with potentially dangerous CO2 levels. That's why CO2 safety alarms are critical in breweries, wineries, beverage dispensing areas, restaurants and fast food establishments, dry ice storage, laboratories, or anywhere CO2 is stored or produced in high volume.

Plant Growth

Indoor gardeners, hydroponic growers and indoor greenhouse growers are constantly looking for new ways to grow bigger and healthier plants. They know that monitoring carbon dioxide, humidity and temperature is critical to achieve the best results.

Personal CO2 Safety in Confined Spaces

Carbon dioxide, in the form of underground off-gassing, dry ice or liquid CO2 delivery systems, or portable heaters can pose a potential deadly threat. Because it is odorless and colorless, workers can easily be overcome by high levels of CO2 in enclosed spaces. Battery operated and portable CO2 monitors with alarms are used in the construction industry, by breweries, machine shops, garages and many other businesses as a low-cost way to warn employees to stay out of enclosed areas with high carbon dioxide levels.

Capnography and Medicine

Capnography is the monitoring of carbon dioxide in the respiratory gases. It is increasingly being used by emergency medical personnel and hospitals as a tool to judge the condition of patients. For example, by measuring the end-tidal CO2 (ETCO2, the level of carbon dioxide released at the end of expiration) through a mask attached to a CO2 sensor, EMS technicians can receive an early warning of a patients worsening condition.

Algae and Biofuel Production

Algae is used to transform water and CO2 into methane and oxygen. High carbon dioxide levels are required to maximize methane production, while low oxygen levels are required to protect the organisms. We offer CO2 sampling meters to insure peak algae production.
