Nitrogen oxide analyzer T200UP

nitrogen dioxidenitrogen monoxidemonitoring

The Model T200UP provides trace level measurements of NO and NO2 using our Model T200U NOx analyzer combined with a patented high efficiency photolytic converter. Even low temperature molybdenum converters transform other nitrogen-containing compounds such as HNO3, PAN, etc. to a considerable extent. Simultaneous measurements of NO2 performed with molybdenum and photolytic converters have shown significantly different results in the presence of such compounds. In the photolytic process the sample gas passes through a cell where it is exposed to light at a specific wavelength from an LED array. This causes the NO2 to be selectively converted to NO with negligible interference from other gases. Combined with the proven Model T200U, it provides ultra-sensitive performance, with a lower detectable limit of 0.05 ppb or better, and is ideally suited for NCore research sites and the low-level direct NO2 measurements required for roadside monitoring. Advances in the photolytic converter technology now yields NO2 conversion efficiency that is similar to molybdenum under typical ambient NO2 concentrations, but without the same interferences. 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 T200UP comes with NumaView™ Software. NumaView™ Remote PC Software allows for a remote connection with virtual interface ​
