Abstract: A gas analyzer system for analyzing and monitoring samples of compressed or ambient gas such as breathing air and informing the user as to the results of the sample's gas purity without the gas sample having to be physically transported to an accredited laboratory. The system comprises a gas analysis module situated at a user facility for receiving the contents of a gas sample and detecting gas impurity characteristics, and a server situated at a remote certification and monitoring center and electrically coupled to the gas analysis module via a bi-directional communications link such a computer network connection. The remote server receives and stores the gas purity characteristics in the form of gas impurity data obtained from the analysis module. The module includes a calibration canister containing a known gas. The module executes onboard calibration by analyzing the calibration gas and comparing it to known data stored on the module.

The remote server receives and stores the gas purity characteristics in the form of computer-readable gas impurity data obtained from the analysis module. The server compares the impurity data with the contents of a database containing threshold gas purity parameters and provides the test results to the user facility by electronic messaging.

Abstract: A gas analyzer system for analyzing samples of compressed or ambient gas such as breathing air within a scuba tank, SCBA or ambient air within an industrial plant and informing the user as to the results of the sample's gas purity without the gas sample having to be physically transported to an accredited laboratory. The system comprises a gas analyzer situated at a user facility for receiving the contents of a gas sample and detecting gas purity characteristics, and a server situated at a remote certified testing site and electrically coupled to the gas analysis module via data transmission, such as a wireless or a computer network connection, wherein the server, maintained by a qualified third party receives and stores the gas purity characteristics in the form of computer-readable data signals.

Abstract: A pressurized air tank air quality tester comprising a housing having a longitudinal bore disposed therein. The housing has at least one closure disposed on at least one of the ends of the housing for sealing the housing and forming an airtight test chamber therein. A valve connector is connected to one of the ends of the housing for fluidly communicating the pressurized air source with the test chamber. An indicating cartridge is removably disposed within the test chamber for indicating by color an excessive amount of a contaminant contained within the test chamber.
