Definition

Active sampling design enables on-field calibration with portable gas cylinders or gas generators. With the help of an Oizom gas hood and on-device remote calibration software the devices can be calibrated on site using standard calibration gas cylinders of known concentration. Spot calibration by collocation. An installed device can also be calibrated by co-locating with a reference standard (which can either be a stationary reference station, an equivalent “gold standard” instrument, a mobile reference instrument, or a freshly calibrated Oizom device) as per US EPA Air Sensor Collocation Instruction Guide.
