The Model N201 NH3 Analyzer uses chemiluminescence detection combined with an external N501 thermal converter, providing accurate and dependable measurements of trace ammonia (NH3), nitric oxide (NO), nitrogen dioxide (NO2), nitrogen oxides (NOX) and total nitrogen compounds (TNX).

Exceptional stability is ensured through an auto-zero reference valve, which corrects for photomultiplier tube (PMT) drift. Operational parameters are continuously tracked with user-configurable alerts, predictive diagnostics and comprehensive data storage capabilities. Data acquisition can be configured conditionally or periodically, enabling in-depth performance monitoring and analysis. Real-time graphs of measured parameters are easily accessible via the intuitive NumaView™ software touchscreen interface.

The N201 instrument functions and controls are managed through a series of integrated microprocessor-controlled modules utilizing a simple and reliable CAN Bus communication architecture. Each module is independently assembled and calibrated allowing easy and fast field replacement to maximize instrument uptime. 

Intuitive operation and calibration of all N Series products is achieved through the NumaView™ Software interface. The graphical user interface (GUI) is customizable, giving the user fast and efficient access to instrument status, as well as measurement data and diagnostic parameters in either numeric or graphical form. NumaView™ Remote Software (included at no charge) provides the same virtual interface and complete instrument control, as well as access to the instrument’s large internal data storage buffer from a remote PC or tablet.
