摘要： A vehicle gas analyzing system for testing gas content in exhaust emitted from a vehicle is disclosed. The vehicle gas analyzing system is of a size and weight to be held in a user's hands. The system includes a housing having outer dimensions no greater than about 12".times.8".times.3", and has an inlet receiving exhaust emitted from the vehicle. A sensor assembly is disposed in the housing, receives the exhaust emitted from the vehicle through the inlet, and determines the content of a plurality of different gases in the exhaust. A user interface is disposed on an outside surface of the housing, allowing a user to input instructions to the system and to perceive output from the system. A control system is disposed in the housing, is operatively coupled with the sensor assembly and the user interface, and is operable to receive and interpret instructions input by a user via the user interface, regulate operations of the sensor assembly in response to the instructions received, receive and interpret results of operations of the sensor assembly, and transmit the results as output to the user interface. A power supplying apparatus is disposed in the housing, receives power from an external source, and delivers power throughout the system. The housing, sensor assembly, user interface, control system, and power supplying apparatus have a combined weight of no greater than about five pounds.
