AEI Technologies

AEI Technologies is a U.S.-based medical device and life science instrumentation company that manufactures and markets metabolic measurement systems and respiratory gas analyzers. The company is best known for the Applied Electrochemistry line of oxygen and carbon dioxide analyzers and for metabolic carts used in research, teaching, clinical studies, and sports medicine. Its products are used for high-accuracy respiratory gas analysis, indirect calorimetry, and respirometry across laboratory and clinical settings. AEI appears to operate as a small private company serving academic, clinical, and performance-testing customers rather than as a therapeutics developer. The business is commercial-stage and focused on instrument sales, service, and support.
