ECO PHYSICS nCLD 822 Mhr

Modular Gas Analyzer

The nCLD 822 Mhr analyzer is the next generation in two-channel high precision nitrogen oxide measurement. Unique in speed and reliability, the nCLD 822 Mhr is modular designed and capable of simultaneously measuring NO, NO2 and NOX from hot and humid gas sources without additional cooler. The new and intuitive graphical user interface “GUI“ also individually displays and connects to other instruments’ data.

nCLD – A New Generation
The nCLD 822 Mhr includes everything that is needed for measuring NO, NO2 and NOX in unpreconditioned gas samples. The fully revised detector-block, the enhanced gas flow paths and the improved pressure as well as temperature independence of the nCLD 800 Series instruments allow for even lower detection limits. Overall stability and reliability are lifted to a new level. The integrated hot tubing enables the instrument to analyze hot and moist sources without external gas preconditioning unit, allowing highly precise analysis. The calibration of the unit runs quickly and automatically, with all necessary data stored and available anywhere and at any time.

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 for your remote operation, control and maintenance of the nCLD 822 Mhr, ensuring unsurpassed precision and reliability.

Compact, Modular and Intelligent!
The nCLD 822 Mhr 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 will conform to the standard method for NOX-detection in stationary source emissions (EN 15267).
