Pod Technologies - Portable Emissions Analyzers
Overview
Procedures for measuring nitrogen oxides (NOx), carbon monoxide (CO), and oxygen (O2) concentrations from combustion sources with portable emissions analyzers are defined by US EPA, New Mexico Environment Department Air Quality Bureau (AQB), Oklahoma Department of Environmental Quality, South Coast Air Quality Management District (SCAQMD), ASTM, and many other regulatory bodies. Links to information and resources on regulations, test methods, evaluations, and analyzers are listed below.
