To perform an accurate calibration of the gas cartridges, a gashood can be used to connect a certified calibration gas cylinder (ISO 6141, NIST) to the Kunak AIR station. This type of calibration is similar to the calibration protocol for reference instruments and requires only two points: baseline and span (sensitivity).
