The Model N500 CAPS NOx analyzer uses superior Cavity Attenuated Phase
Shift (CAPS) Spectroscopy to measure True NO2, NOx, and NO gases. The
instrument combines direct NO2 measurements with highly efficient gas phase
titration (GPT) to convert and measure the NO gas component. An automatic
baseline reference cycle accounts and compensates for any potential baseline
drift due to varying environmental conditions.
CAPS technology is inherently accurate and sensitive, uses very little power,
and requires far less maintenance than Chemiluminescence. The Model
N500 raises the bar for NO2, NOx, and NO measurement accuracy, while
simultaneously reducing instrument operation and maintenance costs.
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. The long-life sample filter further improves efficiency with a ~6 months
exchange interval in ambient air quality monitoring applications.
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
