The Teledyne API Model N802 Paramagnetic Oxygen Analyzer is a microprocessor-controlled analyzer that determines the concentration of molecular oxygen (O2 ) in a sample gas drawn through the instrument. It uses a paramagnetic sensor that relies on the relatively high reactivity of O2 molecules to magnetic fields to generate a current that is proportional to the amount of O2 present in the sensor chamber.

The N802 uses the proven paramagnetic measurement principle, combined with a state-of-theart modular architecture, and intuitive operating software to provide accurate and dependable measurements of percent level O2 . The N802 offers a stable and inherently linear measurement of O2 , making it possible to calibrate the analyzer by checking only two points. There is no requirement for a reference gas during operation.

Instrument functions and controls are managed through a series of integrated microprocessorcontrolled modules utilizing a simple and reliable CAN Bus communications architecture. Each module is independently assembled and calibrated allowing easy and fast field replacement to maximize uptime.

Intuitive operation and calibration of all N Series products is achieved through the NumaView™ Software interface. The graphical user interface (GUI) is customizable, giving the user fast and efficient access to instrument status, as well as measurement data and diagnostic parameters in either numeric or graphical form. NumaView™ Remote Software (included at no charge) provides the same virtual interface and complete instrument control, as well as access to the instrument’s large internal data storage buffer from a remote PC or tablet.​
