The Model T200 NO/NO2/NOx analyzer uses the proven chemiluminescence detection principle, coupled with state-of-the-art electronics to allow accurate and dependable low level measurements for use as an ambient analyzer or dilution CEMS monitor.
A unique AutoZero feature provides superb stability by continuously correcting for zero drift, while advanced Adaptive Filtering allows the analyzer to optimize performance under changing conditions.  The Model T200 includes a permeation inlet dryer for ozone generation to provide excellent reliability with no periodic replacement required.  A catalytic exhaust ozone scrubber is standard for maximum safety and pump life.
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 T200 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​.
