Potential fine dust sources and CO₂ emissions negatively influence home climate and wellness. Seemingly ‘normal’ things such as cooking, hoovering, tobacco and candle smoke, or lighting stoves or fireplaces contribute to this. Increased level of fine dust and CO₂ in the indoor air is responsible for difficulty in concentrating and sleeping, and for allergic reactions. As so-called CO₂ signal lights, measuring instruments serve to minimise the risk of infection during the current pandemic by using the right air. The Trotec Air Quality Monitor BQ30 determines not only the current CO₂ pollution levels but also the fine dust and pollen levels, as well as the prevailing indoor climate data – and displays the quality of the indoor air at a glance.
The BQ30 air quality monitor should be a feature in every classroom, waiting room, meeting room or open-plan office, because this environmental measuring station shows 5 important values for good indoor air at a glance: In addition to the CO₂ levels and the climate temperature and relative humidity data, the fine dust levels with the particle sizes PM2.5 or PM10 is also displayed.
Reliable and precise, with the compact, long-term BQ30 air quality monitor, CO₂ levels as well as critical fine dust concentrations can be traced. For example, the device determines the fine dust levels in the particle sizes PM2.5 (e.g. respirable fine dust, aerosols and other smallest suspended particles) or PM10 (pollen, dust particles from road traffic etc.). The practical all-round measuring device also records air temperature and humidity – everything at a glance!
The CO₂ level is an important indicator for ventilation measures and the determined fine dust particle sizes include not only fine dust (e.g. due to traffic) but also pollen – important for those with allergies!
At a glance – how the signal light function of the BQ30 work
- The large 3″ colour LCD display of the BQ30 simultaneously shows the particle mass concentration in the air, the CO₂ content, the air temperature, the relative humidity as well as the date, the current time and the battery charge level. Additionally, a coloured bar graph indicator shows at a glance whether the particle load is ‘in the green range’.
- In shades of yellow, the BQ30 air quality monitor visually signals that the measured values for PM10/PM2.5 particles are in the ‘normal’ range. If the display is red, there is already a ‘medium’ load. Individual threshold values can also be set on the basis of the pre-defined limit values.
- If the display colour changes to violet or dark purple, the predefined particle quantity limits are markedly exceeded. In order to improve poor air quality in the short term, proper ventilation should be provided, as one example. The values for the CO₂ content in the air are also shown separately, in corresponding colour gradients.
BQ30 − CO₂ monitoring for suggested ventilation
In rooms with a large number of people, CO₂ signal lights can serve as a rough guide to good or bad air, because carbon dioxide (CO₂) is a reliable indicator of air flow. A CO₂ concentration of up to 1,000 ppm indicates hygienically adequate air flow under normal conditions. Even at a CO₂ value of only 1,500 ppm, the ability to concentrate decreases noticeably and headaches, fatigue and even drowsiness can set in. For values above 1,000 ppm, the room should be ventilated so that the values are once more in the 400-500 ppm range. CO₂ signal lights
can thus provide a reliable indication of whether, when and -above all- how long ventilation is necessary. However, the installation of CO₂ sensors does not mean that a CO₂ concentration of less than 1,000 ppm provides essential protection against a SARS-CoV-2 infection. There is no correlation between CO₂ concentration and virus content.
On the other hand, however, CO₂ concentrations significantly or permanently higher than 1,000 ppm in schools, offices and private households indicate inadequate ventilation management with
potentially higher risk of infection. This applies not only to ventilation through windows, but also to the operation of ventilation systems. In addition to the CO₂ values and the fine dust levels, from a hygiene point of view independent of SARS-CoV-2, the correct relative humidity between 40 and 60% is also important. On the one hand this prevents mucous membranes from drying out if the air is too dry below 30% r. h., and on the other hand it prevents mould growth if the relative room air humidity is above 60%. You can view all this information with a glance at the BQ30 room air monitor.
Thanks to the signal light function, you can see whether there is enough fresh air in the room and even how clean it is. The BQ30 is therefore an important indicator for necessary ventilation measures and also helpful for air quality monitoring for allergy sufferers! If necessary, you can improve the indoor climate by increasing the flow of fresh air or with the effective use of air purifiers, humidifiers, or dehumidifiers.
- Load and support
With the BQ30, you no longer have to constantly worry about when it’s time for the next airing. This allows you to concentrate better on your lessons or work.
- Better protection against infection
By airing the room in good time, you can avoid excessive aerosol particle pollution of indoor air.
- Consistent performance
Stay informed on CO₂ content, fine dust particles and pollen particles in the indoor air, and then ventilate to counteract tiredness, chronic coughing or allergic reactions.
