What is a good CO2 value?
A CO2 monitor gives an accurate indication of CO2 values in PPM (Parts per million).
The CO2 monitor will sound an alarm if the CO2 concentration reaches a dangerously high level.
What exactly do the LED indicators on the CO2 monitor mean?
Green: A PPM value of less than 800 means the room is well ventilated.
Orange: A PPM value between 800 and 1200, this means that ventilation is desired.
Red: A PPM value of more than 1200 PPM, ventilation is necessary.
