The Model N100H instrument uses the proven UV fluorescence principle, combined with a state-of-the-art modular architecture, and intuitive operating software to provide accurate and dependable measurements of high range SO2 gas. The instrument includes interferent rejection, providing a simple and precise solution for a broad range of continuous emission monitoring systems (CEMS) and stack testing applications.
The instrument's UV light source is continuously flashed to provide exceptional stability and long lifetime. The instrument design provides minimal quenching by O2 or CO2 and less than a 0.1% response to water in the sample, and special optical filtering reduces the effects of NO interference. Any potential lamp intensity fluctuations or detector drift is automatically managed in real-time using a sophisticated combination of reference readings during the lamp light/dark cycles.
Instrument functions and controls are managed through a series of integrated microprocessor-controlled modules utilizing a simple and reliable CAN Bus communications 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.
