Local engine inspection and testing

Air Liquide is the leading supplier of gases used in local emissions testing garages. Many states employ a certification process to qualify gas blenders for use in decentralized state programs. One of the most often referenced certifications is from California's Bureau of Automotive Repair (BAR). Air Liquide meets state certifications as well as Federal EPA I/M 240 and ASM specifications. We also offer the most widely utilized BAR products and their components; these mixtures are ±1% accurate and NIST-traceable.
