The air-Q can help to obtain LEED certification for your company.

particulates (PM₁ - PM₂,₅ - PM₁₀)

Particulates is a mixture of solid and liquid suspended particles with a very small diameter.Depending on the particle size and composition, particulates can have a lasting effect on the respiratory tract and the cardiovascular system. The air-Q air analyser can measure particulates of different particle sizes (PM₁₀, PM₂,₅, PM₁).

Nitrogen dioxide (NO₂)

Nitrogen dioxide (NO₂) belongs to the group of nitrogen oxides. It is a reddish-brown, chlorine-like and pungent smelling gas.NO₂ has a strong irritating effect on the respiratory tract and promotes asthma.

Carbon dioxide (CO₂)

Carbon dioxide (CO₂) is one of the natural components of air and an important greenhouse gas in the earth's atmosphere. Excessively high carbon dioxide concentrations indoors lead to lower performance and fatigue and even life-threatening respiratory distress.

Carbon monoxide (CO)

Carbon monoxide (CO) is produced, among other things, by the incomplete combustion of substances containing carbon.The colourless, odourless and tasteless gas is a strong respiratory poison that quickly reaches dangerous concentrations in unventilated rooms.

Oxygen (O₂)

Molecular oxygen (O₂) is a colourless and odourless gas that is present in 21 % of the air. On the Earth's surface, oxygen is the most abundant element by mass.

Ozone (O₃)

Ozone (O₃) near the earth is formed by the reaction of oxygen, nitrogen oxides and volatile organic compounds under intense solar radiation.Even in slightly elevated concentrations, it causes severe irritation of the mucous membranes and respiratory tract.

Sulphur dioxide (SO₂)

Sulphur dioxide is a colourless, pungent smelling and sour tasting irritant gas and is perceptible to humans at concentrations between 0.8 and 4.0 mg/m³.

Radon (Rn)

Radon is a noble gas whose decay releases radioactive particles (so-called alpha radiation).

Absolute humidity (φ)

Absolute humidity describes the water vapour density: that is, the mass of water vapour contained in a specified volume of air.

Relative humidity (ρ)

Air humidity refers to the proportion of water vapour in the gas mixture of the air.Humidity that is too high or too low indoors can have a negative impact on people's well-being and health.

Methane (CH₄)

Methane is a combustible gas and the main component of heating gas.

Formaldehyde (CH₂O)

Formaldehyde is a colourless, pungent-smelling substance that is gaseous at room temperature. Due to its use in adhesives, formaldehyde is very common in interiors today and is found in many wood-based materials and furniture.

Air pressure (p)

Air pressure is created by the continuous movement of air masses.As part of the atmospheric environmental conditions, it has a direct influence on human health and well-being.

Noise (Lp)

Sound becomes noise when unwanted noises are perceived as disturbing, annoying or impairing.As a psychosocial stress factor, noise can severely impair well-being and performance.

Noise maximum value (Lp_max)

The noise maximum value, unlike the basic stressful "normal" noise value, reflects acute noise events - such as a short loud bang in the night. These events documented by the noise maximum value can abruptly interrupt rest phases and cause stress.

Air temperature (T)

The air temperature has a significant influence on the reaction time of chemical processes and thus on the metabolic process of humans.It therefore makes sense to measure it. Temperatures that are too high or too low can have a negative impact on mental or physical health.

Light / illuminance (lx)

The light sensor measures the light intensity by detecting the brightness of the incident light and converting it into a digital signal. It only takes into account the light spectrum that can be perceived by the human eye and ignores infrared and ultraviolet radiation.

Volatile Organic Compounds (VOC)

VOCs (Volatile Organic Compounds) are organic, carbon-containing compounds that evaporate even at low temperatures. In many cases, VOCs are largely harmless to living beings - despite their influence on well-being. However, this group of substances also includes substances that are critical to health, such as formaldehyde.

Dew point (Td)

The dew point describes the temperature point at which the relative humidity is 100% and the existing water vapour in the air would immediately begin to condense into water.

Nitrous oxide (laughing gas) (N₂O)

Nitrous oxide is a colorless and tasteless gas with a slightly sweet odor. Under the name laughing gas, it is known primarily from medicine as a painkilling and anesthetic agent.

Hydrogen sulfide (H₂S)

Hydrogen sulphide is a colourless, malodorous and highly toxic gas that is flammable and highly combustible. It has the typical smell of rotten eggs and is produced when proteins from sulphur-containing amino acids are decomposed by putrefactive and sulphur bacteria.

Ammonia (NH₃)

Ammonia (NH₃) is a pungent-smelling, colourless and toxic gas. It irritates the eyes and respiratory tract and has a suffocating effect. Ammonia is one of the most widely produced industrial chemicals. In nature, urea and various salts occur as reaction products.

Hydrogen (H₂)

Hydrogen occurs stably only as molecular hydrogen (H₂) and is a colorless and odorless gas. It reacts quickly with oxygen (O₂) to form water, releasing energy. H₂ is non-toxic but has flammable / explosive properties.

Chlorine / chlorine gas (Cl₂)

Chlorine (Cl₂) is a toxic greenish gas with high reactivity. In low concentrations it irritates the mucous membranes and respiratory tract, in high concentrations it has a corrosive effect.
