The present invention provides apparatus and a methods for collecting, transmitting and storing fugitive gas emission data. An embodiment of the invention collects fugitive gas with a sampling probe and into a emission monitoring device. The device then sends and stores fugitive gas data into a storage medium, such as a wireless data-logging adapter. The wireless-data logging adapter stores the data and wirelessly sends it to a personal digital assistant or other form of redundant memory such as a data logger. In one embodiment, the PDA can initiate commands to retrieve data from the storage medium or operate the emission gas monitoring device.

What is claimed is: 1. An apparatus for communicating and storing emissions data during the emissions measuring process comprising: a first portable light-weight human carriable device and a separate second portable light-weight human carriable device that cooperate as a single portable light-weight human carriable device; said first portable light-weight human carriable device comprising: (a) a sampling probe adapted to receive fugitive emissions; (b) a transport conduit having a first end, connected to the sampling probe, and a second end, wherein the transport conduit is configured to transport a sample of fugitive emissions from the sampling probe; (c) an emissions measuring device connected to the second end of the transport conduit, wherein the emissions measuring device is adapted to receive the sample of fugitive emissions and produce measurement data representing the sample of fugitive emissions; and (d) an adapter having a wireless transceiver operably connected to the emission measuring device, wherein the adapter is configured to transmit a signal representing the measurement data over a radio frequency by operation of the wireless transceiver; and said second portable light-weight human carriable device comprising a hand held personal data assistant having a wireless transceiver, wirelessly connected during the emissions measuring process to the adapter, wherein the personal data assistant is configured to receive the radio frequency signal representing the measurement data over the wireless connection. 2. The apparatus of claim 1 wherein the adapter and/or personal data assistant provides an indication when the wireless connection is dropped. 3. The apparatus of claim 1 wherein the adapter and/or personal data assistant provides an indication when the measurement data is stored. 4. The apparatus of claim 1 wherein the adapter and the personal data assistant each further comprise a storage medium, wherein each storage medium is configured to store the measurement data collected and monitored during the emissions measuring process. 5. The apparatus of claim 1 wherein the adapter and/or personal data assistant provides an indication when the signal representing the measurement data is transmitted over the wireless connection. 6. The apparatus of claim 1, wherein the emissions measuring device further comprises an ignition filament and the personal data assistant is configured to transmit a command to ignite the ignition filament. 7. The apparatus of claims 1 further comprising a microprocessor connected to the emissions measuring device, wherein the microprocessor is configured to determine a level of fugitive gas emissions collected by the sampling probe and convert the level to a signal for wireless transmission from the adapter to the personal data assistant. 8. The apparatus of claim 4 wherein the storage mediums of the adapter and the personal data assistant are configured to store redundant copies of the digital measurement data. 9. An apparatus for storing emissions data comprising: a first portable light-weight human carriable device and a separate second portable light-weight human carriable device that cooperate as a single portable light-weight human carriable device; said first light-weight portable human carriable device comprising: (a) a sampling probe configured to collect a sample of fugitive emissions; (b) a converter connected to the sampling probe, wherein the converter is configured to digitize the sample of fugitive emissions by producing digital measurement data representing the sample of fugitive emissions; and (c) a first storage medium connected to the converter, wherein the first storage medium is configured to store the measurement data; and said second light weight human carriable device comprising a second separate storage medium removably connected to the first storage medium over a wireless communications link; wherein the second storage medium stores a redundant copy of the measurement data. 10. The apparatus of claim 9 wherein the communications link is a radio frequency wireless connection. 11. The apparatus of claim 9 wherein the communications link is connected to the first storage medium or the converter. 12. An apparatus for transmitting emissions data over a wireless communications link comprising: a first portable light-weight human carriable device and a separate second portable light-weight human carriable device that cooperate as a single portable light-weight human carriable device; said first light weight portable human carriable device comprising; (a) a sampling probe configured to collect a sample of fugitive emissions; (b) a converter connected to the sampling probe, wherein the converter is configured to digitize the sample of fugitive emissions by producing digital measurement data representing the sample of fugitive emissions; and (c) a transceiver connected to the converter, wherein the transceiver is configured to wirelessly transmit a radio frequency signal representing the measurement data over a wireless communications link during the emissions measuring process; and said second light-weight portable human carriable device comprising a portable personal data assistant, removably connected to the transceiver over the wireless communication link, wherein the personal data assistant is configured to receive the radio frequency signal representing the measurement data. 13. The apparatus of claim 12 further comprising a first storage medium connected to converter, wherein the first storage medium is configured to store the measurement data. 14. The apparatus of claim 13 further comprising a second storage medium connected to the personal data assistant, wherein the second storage medium is configured for redundant storage of the measurement data. 15. The apparatus of claim 14 wherein the second storage medium is removably connected to the first storage medium over the wireless communications link.
