- Model CLD 84 M - NOx Analyzers



The CLD 84 M NOX analyzer is the ideal instrument for series checks. It is distinguished by high precision and reliable, continuous operation.

  • Four freely selectable measurement ranges up to 500 ppm NO/NOX
  • Locigal user guidance
  • Operation and control via keypad or personal computer
  • Error message coded and in full text
  • Rapid system integration
  • Virtually maintenance- free even in continuous operation.


The CLD 84 M single channel nitrogen oxide analyzer is designed for all applications with an existing gas preconditioning unit to ensure quality control as well as keeping to threshold values.

The design is remarkably compact. All components, even the vacuum pump and the thermal ozone scrubber, are contained in one single unit. In spite of its simple construction the high ECO PHYSICS standard is fully complied with. The instrument includes a temperature stabilized photo multiplier and a high performance ozone generator.

Thanks to its completely modular interior the analyzer is easy to service. The reaction chamber can be removed for cleaning or replacement by following a few simple steps as shown in the picture.

Many more applications are available as options or upgrades at a later date.


The user can choose from four measurement ranges between 0.5 and 500 ppm. The analyzer can be operated via the keypad and remotely from a personal computer. The easy-to-read display with 2 lines of 40 characters each facilitates the gas readings and clarifies the command structure. Simple, intuitive commands are the key to full test procedures tailored to the user's needs. Even system integration can be comfortably planned and easily realized.

The analyzer operates extremely reliably and with outstanding precision. Its design guarantees ease of use and a minimum of maintenance. The oil-free vacuum pump, for example, only needs to be checked once every 12 months.
