Technoline has been a leading specialist for weather stations and meteorological measuring devices for more than 20 years. In search of the latest trends and innovative product ideas, the product portfolio has been expanded to include clocks, alarm clocks, scales, flashlights, electronic products for saving energy, chargers, batteries and rechargeable batteries. The products are characterized primarily by exceptional quality and high reliability, as well as an excellent price and long product availability.

We at air-care.ch carry technoline measuring devices which are used for indoor air quality measurement and have integrated a careful selection of suitable products in our range. In addition to air purifiers, CO₂ monitors also support the improvement of indoor air quality. Thus, regular airing can reduce the concentration of pollutants, viruses and bacteria. The CO₂ monitor or the CO₂ traffic light provides an indication of this and can even remind us to ventilate when CO₂ concentrations reach too high levels.

How CO₂ levels can be used to assess air quality?

The established method for quantifying indoor air quality is to measure CO₂ levels. This measured value is seen as a generally accepted indicator of air freshness. Carbon dioxide is released into the air when exhaled. The CO₂ concentration therefore depends on how many people are in a building and how much fresh air is supplied. In general, the higher the CO₂ concentration in the building compared to the outside air, the lower the amount of fresh air that has been exchanged or supplied. Without sufficient indoor ventilation, the CO₂ content will naturally increase over time.

What CO₂ concentrations are measured?

Outdoors, CO₂ levels are thought to be in the range of 350 to 500 parts per million (ppm)

In a well-ventilated indoor environment, it is generally between 350 and 1,000 ppm. At a value of über 1,000 ppm, a stuffy atmosphere or poor air quality can already be perceived.

How can sensors be used to improve air quality indoors?

Aside from keeping Räume well ventilated to prevent the buildup of pollutants, installing sensors in Büro buildings, schools and other areas of öpublic life could add a little more safety. The arbitrary and also the regular Öffen Lüften is not necessarily the solution to the air problems in our work and living spaces. Depending on the building, existing pollutant emissions, and the number of people within the space in question, occasional ventilation may not be sufficient to achieve the mandated CO₂ levels on a continuous basis.

Good indoor air quality can only be ensured by ventilation controlled by a CO₂ sensor. Technoline's CO₂ sensors can also monitor temperature and humidity to provide a comprehensive view of air quality.

Why CO₂ meters make sense in schools and workplaces?

CO₂ monitoring can ensure that adequate levels of ventilation are provided, thereby ensuring the health and well-being of students and teachers. CO₂ readings can provide immediate insight into the ventilation rate in classrooms. They thus automatically monitor and document the extent to which prescribed ventilation cycles are being adhered to. CO₂ sensors in indoor spaces are also more cost-effective than active ¨monitoring of airflow from outdoor air intakes.

Inadequate ventilation can contribute to fatigue and concentration problems. There are now numerous scientific studies showing that lack of adequate ventilation can impair performance and increase the effective spread of viruses. The added value of CO₂ measurements is that you can constantly monitor and control ventilation to ensure the health and productivity of your students.

In addition to measuring CO₂ concentrations as an indicator of air quality, monitoring humidity is also recommended. Excessive humidity, especially in the summer months, increases the risk of mold growth and thus represents another health risk related to ventilation. Thanks to the integrated temperature and humidity measurement in the technoline measuring stations, they will also efficiently eliminate this risk.
