Information about the device

Device description

The device OZ-ONE is an ozone meter for measuring the ozone concentration in the air. It can also be used to determine the air, dew point and wet-bulb temperature as well as the humidity level of indoor areas.
For assessing the measurements, a Max/Min function (maximum and minimum value), the time-weighted average, the short-term exposure limit and a Hold function for freezing the currently measured value are also available.
When not in use, an automatic switch-off saves the batteries.
Formation, perception and distribution of ozone
The word ozone has become an integral part of our vocabulary and the colourless, toxic gas is part of our everyday life. The irritant effect ozone can have on our eyes and airways has been common knowledge for a few years now, especially since the increasing ozone volume can be attributed to the so-called summer smog. Ozone is further generated during certain industrial processes.
Ozone (chemical symbol: O3) consists of three oxygen atoms. Ozone is created wherever oxygen molecules(O2) in the air are turned into atoms(O) due to electrical energy or UVradiation. It is these atoms that can react with the oxygen molecules to form ozone(O3).
In case of a high solar irradiation ozone forms involving other air pollutants. The nitrogen oxides(NOx) from automobiles, domestic heating systems, power plants and the industry play a major role in this.
Depending on the concentration, ozone can have a very intense smell similar to chlorine, hay or carnations. By nature, the human nose is already vastly superior to most measuring devices: It detects the gas with a concentration of as little as
0.01ml/m3. What this means when compared to other irritant gases is that we humans can already detect even minor quantities of ozone which gives us the opportunity to take corresponding precautions to avoid any hazard caused by the gas in due time. However, our nose also has a crucial disadvantage compared with measuring devices: the so-called habituation effect. After only a brief period of time spent in an ozone-polluted environment we become so acclimated to the smell that we go noseblind.
The impact of ozone on human beings
The sensitivity to ozone depends on its concentration and varies for each individual. Ozone is an oxidative irritant gas, affecting eyes, nose, pharynx and lungs even at low concentrations. The mucous membranes are unable to stop it seeing as ozone is hardly soluble in water. As a result, the gas can be carried deeper into the lungs than other irritant gases. Concentrations of 200 µg/mm3 and higher can cause the following symptoms:
• irritations of the mucous membranes, eyes and the respiratory tract
• hoarseness, coughs and headaches
• feeling of constriction behind the sternum
• reduced physical performance
The main damage is caused in the respiratory tract which can lead to breathing difficulties and a reduced respiratory volume. Late complications can include nosebleeds, a bronchitis (or tracheitis) or a pulmonary oedema. But the transition from irritations without lasting consequences to long-term changes with pathological significance is very smooth.
Ozone threshold and target values
The information threshold for ozone concentrations amounts to 180µg/m3 (1-hour value) and the alert threshold is 240µg/m
3
(1-hour value). From an ozone concentration of 180µg/m3 the media starts to inform the public of the recommended behaviour. Furthermore, a target value has been specified to protect human health: Averaged over three years, the daily maximum 8-hour value of 120µg/m3 must not be exceeded on more than 25days per calendar year. In the long run, the maximum average values determined over an 8-hour period are not supposed to exceed 120µg/m3 altogether. To protect the vegetation, a target value of 18,000µg/m3 applies for a 5-year average. This is the summed up difference between the hourly average values above 80µg/m3 measured during the daylight hours (8a.m. to 8p.m.) in the main growing season between May and July and 80µg/m3.
