ECO PHYSICS nCLD 899 Y

SupremeLine Gas Analyzer

The nCLD 899 Y analyzer is the next generation in high precision nitrogen oxide measurement. Unique in speed and reliability, the nCLD 899 Y is modular designed and capable of detecting lowest quantities of NO, NOx and NO2 in the range of parts per trillion. The new and intuitive graphical user interface “GUI“ also individually displays and connects to other instruments’ data.

Precise and Reliable
The nCLD 899 Y fulfills the requirements of many research groups specializing in detection and monitoring smallest variations of N-containing compounds, such as NO, NOx and NO2. The analyzer is especially designed for high altitude application. The lag time depends on the settings of the pre chambers and can be reduced to seconds. Calibration and adjustment of the unit runs quick and automatic while all necessary Data, including calibration history, instrument status and warning conditions are continuously stored and readily available anywhere and at any time. The pre chambers minimize zero drift and cross sensitivity. This makes it ideally suited for areas with excellent air quality. For specific NO2 measurements, the molybdenum converter may be replaced by the optionally available photolytic converter (PLOC).

User Friendliness with “GUI“
The new touch sensitive graphical user interface “GUI“ enables the user to individually adjust the instrument operation and data management according to his/her needs and applications. The bright 8” monitor gives a clear overview and allows numerical and graphical display of values. Multiple digital in- and outputs guarantee a maximal connectivity and flexibility for the remote operation, control and maintenance of the nCLD 899 Y, ensuring unsurpassed precision and reliability.

Compact, Modular and Intelligent!
The nCLD 899 Y is manufactured in a new compact and modular layout, in which each essential component of the chemiluminescence analyzer hosts its own CPU and interacts with other CPUs by BUS-communication. This assembly increases accessibility and serviceability by reducing wiring and piping. The measurement principle conforms to the standard method for NOx-detection in ambient air (EN 14211).
