- Model CLD 64 - Nitrogen Oxides Analyzers



The new CLD 64 nitrogen oxide analyzer is the economical solution for the continuous measurement of NO, NO2 and NOX concentrations even in the low parts per billion!

  • Compact design
  • Internal ozone generator and scrubber
  • Molybdenum or steel converter for NOX detection
  • Four freely selectable measurement ranges
  • Operation and control via keypad or personal computer
  • Mobile DC operation

We show you even smallest variations

For years ECO PHYSICS has been one of the leading firms in pollutant measurement. Our analyzers come into use wherever concentrations of nitrogen oxide compounds have to be measured.

Either integrated into entire production processes and systems, or as stand-alone devices in monitoring stations, they continuously deliver the exact NO, NO2 and NOX values you require. The design of the instrument is optimized for rack mount and standalone applications.

Economical solution

The CLD 64 fulfils the requirements of outdoor NO2 and total NOX monitoring in fixed or mobile stations. Detecting and monitoring of smallest variations of NO/NOX concentrations is one of the key features. The fast response and lag time in less than a second is unique of its class.

NO2 and total NOX is measured by molybdenum or an optional steel converter.


The development of an ECO PHYSICS analyzer always includes full user comfort. The user can adapt the operation according to his needs and applications by selection of predefined settings via the keypad and remotely from a PC.

Warning and error messages are displayed coded and in full text. The analyzer guides the user step by step to return to normal operation.

Maintenance simply means annual replacement of filters and membranes besides the consumables required by special sampling conditions.

Easy calibration

Calibration is quickly and automatically carried out. This extremely useful feature eliminates the potential risk of erroneous calibrations.

Compact and modular design

The CLD 64 is the most compact unit of its class. Thanks to the totally modular layout and integrated ozone generator and scrubber it is designed for a multitude of applications.
