The progress in HORIBA's emissions measurement systems has been closely connected to trends in vehicle development. Innovations in automotive technology, stemming from emission regulations and implementation of computer control systems, have especially had great influence on analytical technologies. With the advent of emission regulations, HORIBA developed its first automotive emission analyzer, MEXA-1 and constant volume sampler (CVS), in 1964. Ever since, HORIBA has constantly enhanced its devices to accommodate the most recent requirements, such as increased precision to match stricter emission regulations and advanced automation for improved effi ciency of increasingly complex testing. The current model, MEXA-7000 Version 3, built on over forty years of emission analyzer development enables emission analysis of the latest Super Ultra Low Emission Vehicles (SULEV).
