- Model nCLD 66 - Gas Analyzer for Ambient Air Monitoring

From

0

The nCLD 66 is the next generation in one-channel ambient air monitoring instrumentation. Unique in speed and precision, the nCLD 66 is modular designed and expandable to additional nitrogen based parameters. Its graphical user interface “GUI“ also individually displays and connects to other instruments’ data.

  • Range: 50 ppb – 25’000 ppb
  • Minimum Detectable Concentration: 0.5 ppb
  • Parameters: NO / NOx

Flexible Ambient Air Monitoring

The nCLD 66 is the ideal instrument for ambient air monitoring, either installed in racks, fixed monitoring stations or mobile laboratories. Besides the ambient air in the open environment, the analyzer is also suitable for air quality monitoring in production plants and offices (TLV = threshold limit value). The nCLD 66 is a one-channel NOx-detector based on a modular principle. The measurement ranges are individually adjustable, the parameters are NO, NO2 and NOx and the instrument’s inlet operates at ambient pressure. Calibration and adjustment of the unit runs quick and automatic while all necessary data is continuously stored and readily 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 and flexibility for the remote operation, control and maintenance of the nCLD 66, ensuring unsurpassed precision and reliability.

Compact, Modular and Intelligent!

The nCLD 66 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).
