Model T200U NOy with NumaView™ Software
Trace Level Chemiluminescence NO-NOy Analyzer
Trace Level Chemiluminescence NO-NOy Analyzer
The Model T200U NOy analyzer has been developed and refined specifically to address the challenges of NOy monitoring as required, for example, in the US NCore network. It uses the proven chemiluminescence principle and is coupled with a remote NOy converter via umbilical to allow measurements with a lower detectable limit of 50 ppt.
The Model T200U NOy analyzer combines a gold plated reaction cell with an enhanced performance pump, special low noise photomultiplier tube, and unique signal conditioning to provide exceptional sensitivity. In addition, a pre-reactor separates the NO-O3 reaction from background chemiluminescence to allow accurate auto-zero of the analyzer. The remote NOy converter is provided with a stainless steel, NEMA 4X (IP65) enclosure and custom sample umbilical to allow a mounting height of 10 meters. In addition, the converter features a unique purge circuit designed to remove residual calibration gas.
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 T200U NOy 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.
