Air-Fuel Ratio, Oxygen, & Lambda Analyzers
Description:
ECM offers seven high-quality AFR (Lambda) analyzers. All seven analyzers measure AFR using linear lambda sensors. The lambda sensor has revolutionized AFR measurement because of its wide range, fast response, and ease of use. The sensor consists of a spark plug-sized electrochemical cell which is placed directly in the engine's exhaust. The cell responds to O2, CO, H2, and UHCs in the exhaust to determine AFR, Lambda, Equivalence Ratio, and %O2 for fuels of any composition (i.e. H:C, O:C, and N:C ratios, including H2). All of ECM's AFR analyzers can be easily calibrated using ambient air.
