BPIT, Inc. - Model T200P Photolytic True NO2/NO/NOx Analyzer with NumaView™ Software

Model T200P Photolytic True NO2/NO/NOx Analyzer with NumaView™ Software

By: Teledyne Instruments API

The Model T200P provides measurements of NO and NO2 using our Model T200 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.
