Carbon Dioxide Gas Detectors (CO2 Detectors)

CO2Industrial Scientific’s portable multi-gas detectors provide reliable worker protection in industries that use carbon dioxide (CO2). Carbon dioxide emissions directly associated with construction, breweries, agriculture, machine shops, and biofuel production can pose a potentially deadly threat. Because it is odorless and colorless, workers can easily be overcome by high levels of CO2 in confined spaces. In addition to carbon dioxide detection, the MX6 iBrid® and Ventis® Pro multi-gas detectors monitor hydrogen sulfides, explosion limits, and inadequate levels of oxygen.

Despite the fact that we breathe out carbon dioxide and that it is present in the atmosphere (about 400 ppm), its maximum safe level is 5000 ppm (0.5% by volume). It is a product of complete combustion and is found in brewing and other fermentation processes. CO2 along with methane are the primary components in landfill and sewage treatment digester gas. CO2 is used to carbonate beer and possesses a hazard in the brewing industry particularly because CO2 is heavier than air and collects at low levels. There is some degree of risk in crowded, badly ventilated places, and an oxygen deficient atmosphere often accompanies this problem. Another typical practice is to increase plant growth by elevating normal CO2 levels in greenhouses. It is odorless and colorless and difficult to measure in ppm levels, infrared absorption being the usual technique.

Effects of Various CO2 Levels

Carbon Dioxide Level in PPM   

Resulting Conditions on Humans

300 (0.03% vol.)

Nothing happens, normal concentration in air.

3,000 - 5,000

Low concentrations cause increased respiration and headache.

5000 (0.5% vol.)

Lung ventilation increases by 5%. PEL.

10,000 (1.0% vol.)

Symptoms may begin to occur, such as feeling hot and clammy, lack of attention to detail, fatigue, anxiety, loss of energy, weakness in the knees commonly know as (jelly legs).

20,000 (2.0% vol.)

Lung ventilation increases by 50%, headache after several hours of exposure.

(5 to 10% vol.)

Violent panting and fatigue to the point of exhaustion merely from respiration & severe headache. Prolonged exposure at 5% could result in irreversible health effects.
