ECO PHYSICS nCLD 822 Mhr

Modular Gas Analyzer

The nCLD 822 Mhr analyzer is the next generation in high precision nitrogen oxide measurement. Unique in speed and reliability, the nCLD 822 Mhr is modular designed and capable of simultaneously measuring NO, NOx and NO2 from hot and humid gas sources without additional cooler. It features a dual inlet option for assessing two different sources at once. The new and intuitive graphical user interface “GUI“ also individually displays and connects to other instruments’ data.

When Decimals Are Decisive.
The nCLD 88 p fulfills the requirements of many research groups specializing in detection and monitoring smallest quantities of NO2 within less than thirty seconds response time and less than one second lag time. NO2 measurement is accomplished by a sequential detection of NO and NOx by means of the photolytic converter PLC 860. The pre chamber minimizes zero drift and cross sensitivity. This makes it ideally suited for areas with excellent air quality. The photolytic converter PLC 860 can be replaced by the optionally available molybdenum converter. Calibration and adjustment of the unit runs quick and automatic, ensuring unsurpassed precision and reliability.

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 88 p.

Compact, Modular and Intelligent!
The nCLD 88 p 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).
