Abstract: Various environmental systems are disclosed. In accordance with one of the systems, a first and second valve are provided. The valves provide a first air flow path from an air pump to a photo-ionization detector is provided through a pre-filter. The valves also provide a second air flow path from the air pump to the photo-ionization detector so that the pre-filter is isolated from its environmental surroundings. Various other arrangements of environmental monitoring systems with one or more pre-filters are also disclosed.

Abstract: An environmental monitoring system and methods of a site are disclosed. The system includes one or more environmental measurement instruments, of which at least one instrument is capable to measure a concentration of particles in a certain size range. The system may also include an instrument that is capable of measuring a first concentration of particles in a first size range and a second concentration of particles in a second size range. The system may also include an instrument that is capable to measure a wind speed and a wind direction. The system may also include one device capable of recording an image of a location related to the site. The system includes a controller in communication with the one or more environmental measurement instruments, and a display device capable of displaying data generated by the one or more environmental measurement instruments. The system contains a network. Alerts can be provided based on conditions of the environment.

Abstract: An environmental measurement system and method are disclosed. In one aspect of the invention, the system includes a base station having a processor, a plurality of environmental detectors located remotely from the base station that measure one or more environmental conditions that are in communication with the base station to send the measured one or more environmental conditions to the base station and a plurality of user display stations located remotely from the base station that are in communication with the base station and that can display the one or more environmental conditions received from the base station. One or more of the environmental detectors or one or more of the user display stations is mobile. Alternatively, the environmental detectors and the user display stations can both be mobile.
