BPIT, Inc. - Model T200U Trace-level Chemiluminescence NO/NO2/NOx Analyzer with NumaView™ Software

Model T200U Trace-level Chemiluminescence NO/NO2/NOx Analyzer with NumaView™ Software

By: Teledyne Instruments API

The Model T200U Trace-level NO/NO2/NOx analyzer has been developed specifically to address the challenges of low level monitoring as required, for example, in the US NCore network.  It uses the proven chemiluminescence principle and is designed to allow ultra-sensitive measurements with a lower detectable limit of 50 ppt while still meeting the requirements for use as a US EPA compliance analyzer.
