Gas Analyzer


SPX markets its ULTIMA exhaust gas analyzer for both gasoline and diesel-powered vehicles. The analyzer is used in technical vehicle control centers in over 25 countries.

The software must be adapted to each customer, as every country has its own pollution standards.

The objective of this project is to draft technical specifications for the embedded software, based on the pollution control standards for various countries (Italy, Switzerland, Russia, Greece, Romania, etc.).


We wrote and validated the user manuals to complete this assignment.

The software is developed in C and assembly language using a crossed embedded software development system under Windows IARPVCS. The system uses Hitachi H8/3002 micro-controllers.
