Techno Line WL1020 CO2 reading

Air quality monitor for monitoring air quality, with special consideration of carbon dioxide content. Ventilation recommendation for poor air quality (colored background lighting). For a more accurate measurement of air quality, more current is required, therefore the air quality is only displayed when operating with a power supply unit. The ventilation recommendation can also only be given in mains operation; the time, temperature and air humidity values are visible in battery operation.
