The Model N100 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 low-level Sulfur Dioxide (SO2) gas.

The instrument's UV light source is continuously flashed to provide exceptional stability and long lifetime. 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. Hydrocarbon gases that fluoresce at the same wavelength as SO2 gas are removed from the sample stream through a scrubber (i.e. kicker) and prior to detection to eliminate any potential interferences. The long-life sample filter option further improves efficiency with a ~6 month exchange interval in ambient air quality monitoring applications.

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 buff​er from a remote PC or tablet.​
