Abstract
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.
