Techno Line Luftsensor WL 1020 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.This text is machine translated.
