Teledynešs Model 9110AH analyzer uses the field-proven chemiluminescent technique for monitoring high levels of oxides of nitrogen. User-selectable ranges of 5 to 5000 ppm make it ideal for a wide variety of applications including CEM, stack testing, medical inhalation, cement kiln inlet for clinker quality control, and process control.

A choice of NO2 to NO converters handles tough applications such as thermal DeNOx and stack testing. Selectable measurement modes (NO only, NOx only, NO / NOx switching), auto ranging, and remote range control customizes the 9110AH for the end user.

This instrument also offers a built in data acquisition capability using the analyzeršs own internal memory. This allows the logging of multiple parameters including averaged or instantaneous concentration values, calibration data, and operating parameters such as pressure and flow rates. Stored data is easily retrieved through the RS-232 port or from the front panel, allowing the operator to perform predictive diagnostics by tracking parameter trends.

Features include:
• 0-5 to 0-5000 ppm ranges, user selectable in 1 ppm increments
• Independent ranges for NO, NO2 and NOx
• Auto ranging and remote range selection
• Microprocessor controlled
• NO, NOx only or single channel switching
• Multi-tasking software allows viewing test variable while operating
• Continuous self check with alarms
• Bi-directional RS-232 for remote operation
• Adaptive signal filtering optimizes response time
• Temperature and pressure compensation
• Permeation ozone air drier
• Minimum CO2 and H2O interference
