Mountain Air Engineering manufactures portable emission sampling systems and offers equipment training, support services, and equipment design services. 

Mountain Air Engineering has developed the Ratnoze sampling system, which is specialized for characterizing the climate impact of combustion emission sources that have high particle emissions, large emission fluctuations, and are located in remote areas, such as wood stoves, brick kilns, charcoal kilns, burn piles, biochar makers, and diesel engines. The dilution system conditions the emission sample for more representative partitioning of semi-volatile species, such as organic carbon. The real-time sensor data series show emission fluctuations, and the low sample flow rate facilitates long-term sampling to capture full burn cycles. The Ratnoze is a complete sampling system including sampling probes, accessories, and data analysis software.
