NO Analyzers for Atmospheric Research

A Long Tradition of Performance

We have a long–standing tradition of supplying the best ambient and atmospheric research NO analyzers to the world. Our latest and most advanced nCLD ambient and research analyzers, the single channel nCLD AL and 2 reaction chamber nCLD AL2 and the nCLD 899 products, continue that tradition.

The nCLD analyzers offer an integrated hard disk with nearly unlimited storage capacity for data logging, and they can be operated via integrated touch screen or remote Internet connection. A tilted and adjustable front panel optimizes display readability, or you can add an external monitor. The clear layout of the menu structure enables you to take advantage of all analyzer functions almost intuitively, and the structured SQL database lets you easily export data.

The CraNOx II System

CraNOx II System measures NO, NO2, NOy and ozone for the most accurate measurement solutions in the ppb and ppt range. It is the most accurate commercially available system because it calculates the photostatic equilibrium due to the integrated ozone analyzer. The 2–channel CLD 899 analyzer is the heart of our CraNOx II System.

The CLD 800 series

The CLD 800 series is our standard line of research NOx analyzers. The design has incorporated the vacuum pump and thermal ozone destroyer inside the case of the analyzer. We now offer a choice of converters, heated sample inlets, pressure regulation, and dual reaction chambers. The CLD 800 series instruments are ideal for compact applications with reduced power and heat generation requirements.

Accuracy is dependant on range selected. Highest accuracy shown.
Single reaction chamber models analyze NOx or NO, and are ideal for fast response applications. Dual reaction chamber models simultaneously measure NO and NOx and calculate NO2.
