Product list
Indoor air quality monitor. USB power cable. Instruction manual.
Air quality index
FIG 1: good air quality - between 0-799 ppm Co2 equivalent - green flashing
FIG 2: correct air quality - between 800-1199 ppm Co2 equivalent - yellow flashing
FIG 3: moderate air quality - between 1200-1599 ppm Co2 equivalent - orange flashing
FIG 4: poor air quality - between 1600-1999 ppm Co2 equivalent - red flashing
Above 2000 ppm, the 4 colours flash and an alarm sounds.
Getting started
It is not necessary to calibrate the device, it works and functions automatically.
1. Press and hold the "on-off" button for 3 seconds to turn on or off, then it will display the current air
quality settings.
2. The unit shows the calculated CO2 (COV equivalent) concentration, temperature and humidity. The
colour circle will change according to the CO2 concentration.
3. Connect the USB cable to a 5V power supply to charge the unit. The battery icon will flash when
charging and stop when the product is fully charged.
In case of moderate, bad or alert air quality, it is strongly suggested to air the room.
