The portable oxygen analyzer offered by Illinois Instruments uses an electrochemical sensor for accurate measurements of oxygen in most industrial gas streams.  Our portable oxygen analyzer can be either a trace or percent configuration depending on your application.  The trace portable oxygen analyzer, Model 941, has a measuring range of 0-20,000ppm while the percent portable oxygen analyzer, Model 940, has a measuring range of 0-100%.  The portable oxygen analyzer series uses rechargeable batteries that typically last about one week before recharging.
