Operational Theory 3000ZA-3X One of the three sensors has been modified (0-200 ppm range) to sense low levels of oxygen—less than 1 ppm and generate a current proportional to the concentration. The sensor is designed for long term stability and an operating life of 5 years. 2.3 Sample System The sample system delivers gases to the ZrO sensors, located on 2 the cell block, from the analyzer rear panel inlet. Depending on the mode of operation either sample or calibration gas is del
