How Gas Flow Effects Sensor Measurement
We have tested the relationship between the rate at which air is circulated through a CO2 sensor as an example and compared the speed and accuracy of the reading. The tests lead to 3 results:
- Over short periods of time, an ambient air sensor is more accurate if the gas is circulated by a fan.
- Over even short periods of time, a sampling sensor with an air pump pushing gas over it reacts more quickly, and the gas level reading falls off faster than the same sensor dependent on diffusion or a fan for air circulation.
- Over long periods of time the sensor’s accuracy is independent of air circulation.
