Learn more about the different gases commonly used in the smog inspection industry.
Utilized in calibration gas mixtures to ensure the accuracy of gas analyzers used in measuring vehicle emissions. Carbon monoxide levels are critical indicators of incomplete combustion and are a key pollutant measured in smog tests.
Employed as a calibration gas to check the accuracy of CO2 sensors in emissions testing equipment. Carbon dioxide levels are used to evaluate the efficiency of fuel combustion in vehicles.
Used in calibration gas mixtures for testing the accuracy of nitrogen oxide (NOx) analyzers. NOx emissions are significant contributors to smog and are strictly regulated.
Commonly used as a calibration gas to simulate hydrocarbon emissions in smog testing equipment. Propane helps ensure the accuracy of hydrocarbon measurements in vehicle exhaust.
Sometimes used in calibration gas mixtures to represent hydrocarbons in emissions testing. Methane is a component of natural gas and can be present in vehicle emissions.
Used in calibration gas mixtures to verify the accuracy of oxygen sensors in emissions analyzers. Oxygen levels are important for assessing combustion efficiency and emissions control.
Used as a balance gas in calibration gas mixtures and as an inert gas for purging and maintaining equipment. Nitrogen ensures the stability and accuracy of gas mixtures used in calibrating emissions analyzers.

Smog inspection facilities use calibration gases, often a mixture of nitrogen and trace gases, to ensure the accuracy of emission testing equipment.
Yes. We offer real-time monitoring for most of our gas applications to make sure you never run out. Our solution provides you (and us) with accurate updates on your levels so we can optimize your gas delivery, detect leaks and other issues – saving you money while supporting our sustainability commitments.
Yes. We make true same-day deliveries with no qualifications. If you call at 4:55 pm and you need a same-day delivery, we will deliver that day.
We offer cost-effective bulk gas solutions including bulk calibration gases often used for smog inspections. Your products will be safely delivered by our modern fleet of fuel-efficient trucks, equipped for cylinder and bulk gas delivery.
Yes. WestAir barcodes each cylinder and will scan each cylinder when it enters and leaves your location. This eliminates the need for you to perform time-consuming and error-prone inventory tracking. This process also guarantees accurate monthly billing statements.
Yes. Our dedicated account management and 24/7 emergency service is there to make a bad day better.
