The Model T204 combines proven Chemiluminescence and UV absorption measurement technologies together to create the world’s first US EPA-approved NO / NO2 / NOx / O3 instrument.​ The Model T204 is ideal for urban airshed monitoring, traffic studies, or stand alone NOx/O3 monitoring. ​The T204 allows reduced integration and procurement costs while providing a simple, stable, and reliable monitoring solution.

The chemiluminescence NO/NO2/NOx channel uses the proven TAPI optical bench and pneumatics of the T200, while the compact UV absorption ozone sensor is adapted from the TAPI 465L ambient ozone monitor. In combination, these two technologies solve many of the problems of users that require a high performance analyzer in a smaller, more cost-effective package.

All T Series instruments offer an advanced color display, capacitive touch screen, intuitive user interface, flexible I/0, 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 T204 comes with the Numaview™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface and data downloading capability to analyzers operating NumaView™ Software.​
