Analytical Industries Inc. was founded by individuals whose entire work experience centered on the design, manufacture and application of electrochemical galvanic fuel cell type oxygen sensors and analyzers. The extent of their expertise includes the development of the patents (original and most recent) and proprietary manufacturing processes; pioneering the application and sample conditioning considerations; and, a thorough understanding of the competition. Formed in 1994, Analytical Industries Inc. started with a clean sheet of paper, 60 years of combined experience (which has grown to over 100 years) and devoted the entire first year in business to R&D for the sole purpose of advancing the existing sensor technology. Analytical Industries Inc., doing business in the industrial marketplace under the trade name Advanced Instruments Inc., has earned a reputation around the world for innovative solutions to gas analysis that encompasses the design and manufacture of advanced oxygen sensors and analyzer platforms, a passion for consistent quality and superior customer support. As a result, we have become a leading worlwide supplier of oxygen sensors and oxygen analyzers to the industrial process control, natural gas, medical and diving industries.
