CO2 Sensors vs. VOC Sensors for IAQ - What's the Difference?

Why is Measuring CO2 Important?

Measure carbon dioxide levels for:

1. Indoor Air Quality

CO2 Meter in school classroomWhen 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 sensors to regulate airflow in modern office buildings.

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

2. Energy Savings

Carbon dioxide sensors are used in LEED certified and on-demand HVAC systems to conserve energy. Rather than continuously “dumping” conditioned air, a carbon dioxide sensor 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 controls can result in up to 50% energy savings.

3. 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. Fortunately, it is no longer necessary to purchase three different products – our AQ100, TIM10 and hand held pSense meters do it all.

4. Toxic CO2 Levels

Carbon dioxide, in the form of dry ice or liquid in canisters, can pose a potential deadly threat when stored in enclosed spaces. Our portable CO2 monitors with alarms are used by breweries, restaurants, machine shops, garages and many other businesses as a low-cost way to warn employees to stay out of enclosed areas with high CO2 levels.
