Abstract
Portable gas detection and/or monitoring apparatus including a case having a substantially cylindrical wall and two opposite end caps sealably connected to the cylindrical wall, at least one of the end caps being removable from the cylindrical wall, and at least a portion of the cylindrical wall being transparent. A gas detection and/or monitoring unit is mounted in the case and includes gas sensing means in sealed fluid communication with the ambient atmosphere outside the case. Data processing means is operatively connected to the gas sensing means, and data storage means and information display means is operatively connected to the data processing means. Calibrating means is operatively connected to the data processing means for calibration thereof to a predetermined gas concentration measured by the gas sensing means, the calibrating means including externally operable switching means for selectively connecting the data processing means to the data storage means to allow transfer of data from said data storage means to said data processing means. Communication means is operatively connected to the data processing means or the data storage means for communicating data to the dat…
