摘要 |
A calibration adaptor for a gas sensing device having a gas entry port therein includes a base piece having a gas entry port therein which is fixedly attached to a surface of the gas sensing device, and provided with means for releasably retaining the base piece in a first position in which the gas entry port of the gas sensing device is open to detect ambient gases, and means for moving the attached base piece to a second position in which the gas entry port of the base piece is aligned with the gas entry port of the gas sensing device, and controls entry of gas into the gas entry port of the gas sensing device. A calibration gas source may be attached to the gas entry port of the base piece.
