Oxides of Nitrogen Analyzer Family

The Oxides of Nitrogen Analyzer family contain four instruments from the EC9841 series ( 1 trace, 2 standard and 1 high range instrument). The EC9841 instruments are U.S. EPA approved for the detection of Oxides of Nitrogen (see resources at bottom of page).This family of instruments also contain two other instruments:

The EC9842 measures Ammonia (NH₃), Oxides of Nitrogen (NO_X) and Total Nitrogen Compounds (N_X)
The EC9843 measures Total Reactive Nitrogen Oxides (NO_y) and NO in the ambient air.


EC9841T Trace NO_X analyzer
The EC9841T is specially designed to accurately measure NO_X over a range of 0-2ppm and can be used either in a system or as a standalone instrument.

EC9842 Ammonia analyzer
The EC9842 Ammonia analyzer can sample and detect Ammonia (NH₃), Oxides of Nitrogen (NOx) and total nitrogen compounds (N_X) in ambient air over a range of 0-2000ppb. The EC9842 Ammonia analyzer is used in conjunction with an ammonia converter the Ecotech HTO-1000N.
Brochure

9843 Total Reactive Nitrogen Oxides analyzer
The EC9842 Total Reactive Nitrogen Oxides analyzer can sample and detect Total Reactive Nitrogen Oxides (NO_y) and Nitrogen Oxide (NO) in ambient air over a range of 0-2000ppb. The EC9842 Ammonia analyzer is used in conjunction with a NO_y converter the Ecotech NO_y-1000.
