- Model nCLD 855 CY - Modular Gas Analyzer



The nCLD 855 CY analyzer is the next generation in two-channel high precision nitrogen oxide measurement. Unique in speed and reliability, the nCLD 855 CY is modular designed and capable of sequentially measuring NO, NO2, NOX, NH3 and NOX-Amines. The new and intuitive graphical user interface also individually displays and connects to other instruments’ data.

  • RANGE: 100 ppb – 50’000 ppb
  • Max. NH3 Concentration: 5’000 ppb
  • Minimum Detectable Concentration: 0.4 ppb

nCLD – A New Generation

The nCLD 855 CY includes everything for measurement of NO, NO2, NOX, NH3 and NOX-Amines. 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. The bright 7” 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 855 CY, ensuring unsurpassed precision and reliability.

Compact, Modular and Intelligent!

The nCLD 855 CY 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 ambient air (EN 14211).
