Simple to use HMI

Our range of oxygen analyzers are designed to monitor gas produced or used in industrial processes where trace oxygen from low parts per million to pure O2 must be precisely measured. Utilizing AII’s high performance galvanic oxygen sensors these advanced instruments are simple to use with a common HMI and menu structure across-the-range chassis. Operators only need to learn just one instrument for multiple gas analysis applications at various oxygen levels. Available as bench-, 19" rack-, panel- and wall-mounted for flexible installation.
