Model - SMART 1504

Portable Computerized Opacity Meter and Gas Analyzer Combo

Our portable advanced automotive emission analyzer SMART 1504 has more than twelve years of proven performance being used in applications such as general gasoline and diesel emission testing and in advanced scientific and environmental applications. SMART 1504 has been the favorite choice in many road testing applications. Its rugged design and portability allow it to be installed inside any motor vehicle in minutes, ready for on-road testing. For more advanced applications, we offer SMART 2000xx and 2000xxx versions equipped with a CLD , FID, NDIR gas benches and other sensors, including exhaust gas flowmeter modules that in combination measure each exhaust gas component mass in "real driving" on board configuration, or stationary setting coupled witch chassis dynamometer during driving cycles such as FTP-75 or ECE-15. SMART 1504 has automated self test, zero, and span calibration procedures. The system operates under PC supervisory control that incorporates data logging, strip chart emulation and virtual instrument real time display functions.
