A stationary gas monitoring and testing system includes one or more gas monitoring stations, each of which includes at least one gas sensor. The system also includes a supply of testing span gas, a supply of testing zero gas, a gas distribution network connecting each gas sensor to the span gas supply and the zero gas supply through substantially separate conduits, and a controller for enabling the delivery of gas from the supply into the network for delivery to the one or more sensors. A one-way poppet valve at each gas monitor allows the supply conduits to be pressurized in advance. Pre-pressurized separate supply conduits minimize or eliminate the delay in delivering gas to each sensor for testing and calibration.

Automated stationary gas sensor calibration system and method

A docking station for use with an environmental monitoring instrument to provide predictive diagnostic information. The docking station is connected, typically via the Internet, to a remote service center, and exposure data, calibration data and diagnostic data are communicated from the instrument to the docking station and from the docking station to the service center. Mathematical analysis of the collected data from all available sources is performed at the service center and predictive warnings are generated to alert the users of potential instrument faults, thus allowing preemptive maintenance. The analysis methods include principle component analysis and other statistical methods, fuzzy logic and neural networks. This docking station can be used with monitoring instruments for water quality, pollution control, indoor air quality and breathing air quality.
