The Model 201E NH3 analyzer measures ambient ammonia in selectable ranges from 0-50 ppb to 0-2,000 ppb using the chemiluminescence principle and an APIdesigned external ammonia converter and sampling system.
The Models 101E/102E provide a dependable, accurate and convenient method of measuring hydrogen sulfide or Total Reduced Sulfur (TRS) in levels commonly required for Ambient Air monitoring, offering ranges from 0-50 ppb to 0-10 ppm. Both analyzers convert sulfur gases to sulfur dioxide and measure concentrations using fluorescence technology.
In urban air quality monitoring applications, an Opsis system is typically installed at roof-top level. One or more light paths will simultaneously monitor a number of userdefined compounds over large areas. This provides data both for real-time air quality monitoring and for the analysis of long-term trends.
Air quality monitoring involves the measurement of pollution in ambient conditions. Monitoring the air quality is important in protecting the health of populations and is performed by Ambient Air Quality Monitoring Stations (AAQMS) that are totally integrated with gas analyzers, particulate monitors, calibration equipment, data loggers and ...
The Opsis HG200 mercury analyser is used in three major monitoring applications –in the ambient air, in industrial areas and in public buildings. The analyser monitors both total and atomic mercury. The portable HG200 is easy to use and install. It presents stable and reliable monitoring in all applications.
