Engine Emission Testing

High precision gas mixtures and industry-compliant high-purity instrumentation gases

Air Liquide - Calibration mixtures and pure gases manufactured with dual compliance to EPA and EURO norms that provide a single certificate for global compliance to Engine Testing legislation.

Air Liquide’s unique Acublend technology provides calibration gas mixtures with high batch to batch reproducibility that reduces calibration drift at cylinder changeover.

The mixtures accompany our high-purity instrument gases, which are quality assured for engine testing analysis equipment.
Calibration mixtures are traceable to NIST, VSL or NPL primary reference standards and are available with short lead times and certificates available in hard-copy or on-line.
