Abstract
A continuous gas detection and monitoring apparatus includes a gas detection and monitoring unit mounted in a sealable case, and a gas sensor in sealed fluid communication with an ambient atmosphere outside the case, a temperature and humidity sensor in sealed fluid communication with the inner volume of the case, a pressure sensor, data storage, and a gas sensor operatively connected to a data processor, and an externally operable switch for selectively connecting the data processor to the data storage to allow data transfer from the data storage to the data processor. A plumbing system includes a pump system, a solenoid system, and tubes interconnecting the gas sensor, pumping system, solenoid system, and ambient external environment. The gas sensor is mounted to the gas sensor housing and is in sealed fluid communication with the external environment via the plumbing system.
