			Advanced Instruments Advanced Instruments has developed numerous breakthrough technologies for Oxygen analyzers. The company has developed a Pico-Ion sensor validted to 1 ppb capability and developed the first electrochemical sensor based oxygen purity analyzer.		General Purpose PPM and Percent Oxygen Analyzers Advanced Instruments PPM Oxygen analyzers use a proprietary MS Pico-Ion sensor capable of oxygen analysis under 10 ppb. Most models are available in ranges between 0-1000ppm. Advances Instruments Percent Oxygen analyzers use a proprietary advanced galvanic sensor capable of oxygen analysis under 100 ppb. Most models are available in ranges between 0-25%. The galvanic sensor can be used for ppm ranges as well. Hazardous Area PPM and Percent Oxygen Analyzers Oxygen analyzers are available in NEMA4 and CENELEC approved enclosures. Portable PPM and Percent Oxygen Analyzers Advanced Instruments Portable PERCENT analyzers are available in ranges from 0-1% to 1-100%.
