About this product
Make room for fresher air.
See carbon dioxide, temperature and humidity together on a compact rechargeable display. Follow changes through the day and check how your room responds to ventilation.
See carbon dioxide, temperature and humidity together on a compact rechargeable display. Follow changes through the day and check how your room responds to ventilation.
This is a ventilation indicator. It does not measure carbon monoxide, smoke, fine particles or VOCs, and it does not replace a smoke alarm or CO alarm.
Place the meter where people spend time, with air able to circulate around it. Avoid breathing directly onto the sensor or placing it immediately beside a window, fan or heater.
Read trends over time. A change in occupancy, an open door or a ventilation adjustment can change the CO2 reading. A single number does not establish that the whole room is safe.
Charge through the USB Type-C port. The device can keep displaying readings while connected to power. Battery running time depends on use; charge before moving it between rooms.
