Information for measuring with GF2 CO
2
sensor
With this sensor resp. calibration curve the air quality can be measured. The
measuring range is up to 5000ppm (parts per million).
By putting on and tightening the sensor is activated. The CO
2
sensor
measures in intervals of 15 seconds.
The CO
2
value is the essential criterion for evaluating the air quality.
The following chart shows the correlation of measuring value and well being:
