The Model T802 O2 analyzer uses the proven paramagnetic measurement principle, coupled with state of the art microprocessor technology, to provide accurate and dependable measurements of Percent-Level O2. The Model T802 can also be equipped with an optional CO2 sensor, using the robust non-dispersed infrared (NDIR) measurement principle.​

Paramagnetic technology is non-depleting, which means that there are no consumable parts, and ensures a consistent performance over time. The selectivity of the paramagnetic measurement for oxygen means that there is little or no interference from other common background gases.  The T802 offers a stable and inherently linear measurement of oxygen, making it possible to calibrate the analyzer by checking only two points. There is no requirement for a reference gas during operation.

All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/O, and built-in data acquisition capability.  All instrument set up, control and access to stored data and diagnostic information is available through the front panel, or via RS232, Ethernet, or USB com ports, either locally or by remote connection.

The Model T802 comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software. ​
