Measurements

Get the measure of your air

Accurately measure a range of common airborne pollutants using industry-leading sensor technology.

Nitrogen Dioxide (NO2)

Nitrogen Dioxide (NO2) is a highly reactive gas formed via the oxidation of nitric oxide. NO2 is typically used as a signifier for the presence of other nitrogen oxides (NOx).

Nitrogen Oxides (NOx)

Nitrogen oxides (NOx) is a collective term used to refer to nitrogen monoxide (nitric oxide or NO) and nitrogen dioxide (NO2).

PM2.5

The U.S. EPA defines particulate air pollution as an air-suspended mixture of both solid and liquid particles. PM2.5, known as fine particles, poses the greatest health risk.

PM10

The U.S. EPA defines particulate air pollution as an air-suspended mixture of both solid and liquid particles. PM10 refers to particles less than 10µm (micrometers) in diameter.

Total Suspended Particulate (TSP)

The U.S. EPA defines particulate air pollution as an air-suspended mixture of both solid and liquid particles. TSP includes airborne particles > 10µm (micrometers) in diameter.

Wind

Wind is a critical factor when measuring particulate matter or designing a dust monitoring plan (for example, during construction or remediation activities.)

Noise

Noise has been defined as an “unwanted or disturbing sound.” Unwanted sound can be anything that interferes with normal activities (like sleeping) or impacts one’s quality of life.

Ozone (O3)

Ozone is an unstable gas formed by the combination of three oxygen atoms. Ground-level ozone can cause health risks and harmfully impact the environment.

Carbon Monoxide (CO)

Carbon monoxide (CO) consists of one carbon atom and one oxygen atom. It is a toxic, odorless, colorless gas found naturally at low concentrations in the atmosphere.

Read more

Carbon Dioxide (CO2)

Carbon Dioxide (CO2) is composed of a carbon atom bonded to two oxygen atoms. It’s a naturally occurring gas that is fundamental for life on Earth.

Read more

Sulfur Dioxide (SO2)

Sulfur Dioxide (SO2) is a toxic gas with a strong irritating smell, used across a range of industries - such as winemaking and for dried fruits, due to its antimicrobial properties.

Read more

Volatile Organic Compounds (VOCs)

Volatile organic compounds (VOCs) include a wide range of carbon-based chemicals (or compounds) found in various man-made and naturally-occurring solids and liquids.

Hydrogen Sulfide (H2S)

Hydrogen sulfide (H2S) is a naturally occurring colorless, toxic gas, notable for its very distinct odor (like rotten eggs) even at very low concentrations.

Read more

Hydrogen

Hydrogen (H) is the most abundant chemical substance in the universe. Pure hydrogen gas (H2) is scarce in the Earth’s atmosphere as it is lighter than air.

Read more

Ammonia (NH3)

Ammonia (NH3) consists of nitrogen and hydrogen atoms. It is an important compound in many biological processes and is a key part of the nitrogen cycle.

Read more

Chlorine (CL2)

Chlorine (CL2) is a toxic gas made up of two chlorine atoms. Chlorine plays an important role in water sanitation as it can kill bacteria and other microbes present in water.

Read more

Formaldehyde (CH2O)

Formaldehyde (CH2O) is a naturally-occurring organic compound known for its pungent, irritating odor. It’s found in nature and is used in several industrial applications.

Read more

Methane (CH4)

Methane gas (CH4) is a chemical compound made up of one carbon atom and four hydrogen atoms. It’s the main component of natural gas and is used for fuel.

Read more

Perchloroethylene (C2CL4)

Perchloroethylene (C2CL4), sometimes referred to as Tetrachloroethylene, is a colorless liquid commonly used in dry cleaning and metal degreasing.
