Modular Gas Analyzer

The nCLD 82 Mh analyzer is the next generation in high precision single channel nitrogen oxide measurement. Unique in speed and reliability, the nCLD 82 Mh is modular designed and capable of measuring NOx from hot and humid gas sources without additional cooler. Furthermore, the nCLD 82 Mh is expandable to other nitrogen oxide based parameters. The new and intuitive graphical user interface “GUI“ also individually displays and connects to other instruments’ data.

Straight From the Source
The nCLD 82 Mh includes everything that is needed for measuring NOx in unpreconditioned gas samples. The integrated hot tubing enables the instrument to analyze hot and moist sources and the optional electro-mechanical bypass system balances out pressure variations occurring in the sample flow. Furthermore, the analyzer is adaptable to numerous non-standardized applications. Dual sample gas inlet is an option that allows the user to measure two sources in parallel, enabling comparison of the samples. Calibration and adjustment of the unit runs quick and automatically, while all necessary data is continuously stored and available anywhere and at any time.

User Friendliness with “GUI“
The new and intuitive 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 82 Mh.

Compact, Modular and Intelligent!
The nCLD 82 Mh 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 stationary source emissions (EN 14792).
