Abstract
The present invention is an apparatus for measuring emissions. The apparatus comprises means for obtaining a sample flow, which is a controlled proportion of the total emissions to be measured, and means for accumulating the sample flow in a tamper-proof container (or containers). The tamper-proof container may comprise known chemical reagents with which the accumulated samples react to provide a measure of one or more selected components within said sample. The tamper-proof container may comprise an inlet-port that is adapted to be sealed when said container is disconnected from receiving emissions and may further be adapted to be connected to an external device and to communicate with the external device to provide information about the emission measures. In addition to this, the tamper-proof container may also be removable, transportable and adapted to be connected to an external device under authorised conditions only, thereby providing a system for secure measurement and recordal of emissions.

25. An apparatus for measuring emissions comprising:
-
means for obtaining a sample flow (9), the sample flow being a controlled proportion of the total emissions to be measured;
means for accumulating said sample flow in a housing, said housing containing one or more known chemical reagents with which the accumulated samples react to provide a measure of one or more selected components within said sample, said means for accumulating comprising a plurality of separate accumulation devices, each containing at least one respective chemical reagent, characterized in that said housing is tamper-proof, and in that the apparatus further comprises means (41) for detecting the location of the apparatus; and
switching means (31) adapted to direct the sample to one or other of said accumulation devices according to geographical location and/or time of year or adapted to switch the accumulating means on or off depending upon location and/or at selected times.
