- Model CLD 899 Y - Dual Reaction Chamber Analyzers



The CLD 899 Y nitrogen oxide analyzer is unique in its precision. It allows with the internal molybdenum converter or the external PLC 860 (CraNOx II system) the simultaneous measurement of NO and NO2 concentrations even in the range of low parts per trillion!

  • Compact design without any additional space required
  • Photolytic converter for NO2 detection
  • Pre-chamber to offset cross sensitivity
  • Four freely selectable measurement ranges
  • Operation and control via touch screen

The CLD 899 Y fulfills the requirements of many research groups specializing in detecting and monitoring smallest variations of NO, NOX and NO2 concentrations. The instrument is especially designed for high altitude application. The lag time depends on the settings of the pre-chambers and can be reduced to seconds. The prechamber minimizes zero drift and cross sensitivity by other gases. This makes it ideally suited for ambient air monitoring. For specific NO2 measurements the molybdenum converter may be replaced by the optionally available photolytic converter (PLOC). This would upgrade the device to a complete CraNOx II system, inclusive ozone analyzer and calibrator.

The development of an ECO PHYSICS analyzer always requires full user comfort. The user can adapt the operation according to his needs by selection of predefined settings.

The CLD 899 Y is the most comprehensive unit of its class. Thanks to the totally modular layout and the rich variety of options this analyzer is designed for a multitude of applications. The use of first-rate components guarantees virtually service-free operation. Maintenance simply means annual replacement of filters and membranes besides the consumables required by special sampling conditions.

The new designed graphical user interface enables easy access to various functions by touch screen technology. Integrated user management and configuration menus guarantee maximum flexibility for custom specific needs. Warnings and error messages, as well as user guidance, are displayed for easy identification. Online data are displayed numerical and graphical. The operator may use standard settings or user specific options like zoom functions. A standard feature is the data logger function for up to one year storage capability.
