The T500U CAPS NO2 Analyzer represents the next generation of criteria pollutant monitoring technology for the direct measurement of Nitrogen Dioxide (NO2) in air. The instrument utilizes a patented Cavity Attenuated Phase Shift (CAPS) technique to provide an extremely sensitive, fast and accurate NO2 measurement in a cost effective and low maintenance instrument package.

The T500U provides a direct NO2 measurement, eliminating the need for catalytic conversion or reagents which introduce measurement artifacts inherent in traditional heated metal converter based chemiluminescence instruments.

​​The CAPS measurement approach also reduces maintenance items, and removes the nee​d for hazardous materials and high temperature scrubbers within the instrument. The T500U has an expec​​​ted maintenance interval of one year under typical ambient monitoring conditions.

​​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 T500U 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.​
