How to Use Air Sensors: Air Sensor Guidebook | US EPA

Before using a sensor to monitor air quality, consider possible sensor interferences, test for them, and minimize them if possible. Drift – refers to a gradual change in a sensor’s response characteristics over time. Instrument drift may lead you to wrongly conclude that concentrations have increased or decreased over time. Drift can be positive or negative, and it may occur due to a ...
