Description

The WL4 AQCO2-1 is a stand alone air quality meter for CO2 (carbon dioxide), temperature and humidity. The meter monitors air quality and emits a light and sound signal as soon as a CO2 value is exceeded and ventilation is required. A CO2 meter is mandatory in classrooms in the Netherlands.

De meter werkt op USB voeding (niet meegeleverd). Een bijpassende USB adapter is opgenomen onder het tabblad ‘Opties’.
