Whenever we breathe and speak, aerosols are produced. Normally unproblematic, these can, however, also transmit pathogens and viruses. The risk of infection is much higher indoors than outdoors. Aerosols remain in the air longer, which means that the risk of unnoticed spread of pathogens is constantly increasing. It is therefore important to keep an eye on aerosol levels when several people are in the same room.
CO2 measuring devices, for example from Testo, can help. The risk of infection can then be minimised by timely ventilation, because scientific studies have proven a connection between CO2 content and aerosol concentration. Indoors, a CO2 content of 1,000 ppm (parts per million) is acceptable – the outdoor air, by comparison, has a value of 400 ppm.
Fixed point for CO2 measurement – the mini data logger testo 160 IAQ
The easy-to-use wireless data logger testo 160 IAQ is ideal for continuous monitoring of indoor air quality. Once installed, it precisely determines the climate conditions in any room thanks to its sensors for temperature, humidity, CO2 and atmospheric pressure. The high accuracy of the measurement makes it particularly suitable for professional use, for example in facility management.It is particularly intuitive to operate and indicates the quality of the room air with the help of coloured LEDs in the traffic light principle. Individual CO2 limit values can even be set. If these are exceeded, you can be alerted by e-mail or SMS.
The data logger transmits all measurement data directly to the Testo Cloud via WLAN. This makes it possible to document and evaluate them over a longer period of time – and from anywhere, because you can also access all functions via mobile devices.
Perfect for mobile measurement – the CO2 set testo 440
The mobile climate measuring instrument testo 440 and the humidity-temperature probe with Bluetooth® come safely stowed away in a practical case. The clearly structured measuring menu enables both long-term measurement and simultaneous determination of humidity and temperature. In addition, you can precisely calculate the dew point, wet bulb temperature and absolute humidity in rooms with the testo 440. These functions make the measuring instrument predestined for use in storage, cooling and work rooms – and yet intuitive to use.The internal data memory helps you to save your data, which you can also export to external devices thanks to a USB interface. Since the testo 440 is expandable with a large portfolio of digital probes, it adapts to your individual requirements.
