The nCLD 822 M analyzer is the next generation in two-channel high precision nitrogen oxide measurement. Unique in speed and reliability, the nCLD 822 M is modular designed and capable of simultaneously measuring NO, NO2 and NOX. The analyzer’s expandable capabilities allow assessment of hot and humid gas sources without additional cooler. The new and intuitive graphical user interface also individually displays and connects to other instruments’ data.
nCLD – A New Generation The nCLD 822 M includes everything for measurement of NO, NO2 and NOX. 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 optional electro-mechanical bypass system balances out even fastest pressure variations occurring in the sample flow. Furthermore, the analyzer is adaptable to numerous non-standardized applications. The calibration of the unit runs quickly and automatically, with all necessary data available anywhere and at any time.
User Friendliness The new touch sensitive graphical user interface enables the user to individually adjust the instrument operation and data management according to his/ her needs and applications. Multiple digital in- and outputs guarantee a maximal connectivity for your remote operation, control and maintenance of the nCLD 822 M, ensuring unsurpassed precision and reliability while all necessary data is readily available anywhere and at any time.
Compact, Modular and Intelligent! The nCLD 822 M 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).
