As the largest industrial and specialty gases company in North and South America, and one of the largest world wide, we provide accurate,
reliable NIST traceable calibration gases that meet or exceed regulatory standards for your engine emission bench testing needs. From supplying repeatable, high-quality EPA gases, to designing and installing our state-of-the-art ProSpec™
Gas Delivery Systems, you can count on Linde for consistent high quality products, systems, service and support.
Linde is a pioneer in producing highly accurate calibration gas standards and ultra-pure zero gases for engine emissions
testing. Our environmental solutions help ensure regulatory compliance,
increase capacity, improve economics and achieve a broad range of environmental benefits.
Our emissions testing products are developed in compliance with the current regulatory requirements of federal, provincial, state and local air quality authorities. When you choose Linde, you get a single, proven supplier of consistent high-quality products and services for your engine emissions testing needs.
Federal, Provincial and State vehicle emission regulations require certification of tailpipe emissions to prescribed levels. These regulations mainly deal with in-use certification for currently owned and licensed on-road vehicles. High pressure precision
gas mixtures, in various concentrations, are also supplied to original equipment manufacturers for new engine certification of internal
combustion engines (ICE).
A wide range of high purity gases and calibration standards, blended to the manufacturers exacting specifications, are available. In-use testing is traditionally referred to as Inspection and Maintenance (I/M)
testing. I/M automotive calibration standards are referred to as “BAR” mixtures, and are defined by the California Bureau of Automotive Repair.
