Model AC32M - Chemiluminescent Nitrogen Oxides Analyzer
From Analyzers
The new Chemiluminescent NO-N02-NOx analyzer, model AC32M, combines our 20 years of experience with its predecessors AC30M & AC31M, with an enhanced electronics package and a modular component parts design. The outcome is an ultra compact and light- rack 3U, easy-to-use, che-miluminescence based analyzer capable of measuring nitrogen oxides at ppb levels. Applied to nitrogen oxides measurement, Chemiluminescence corresponds to an oxidation of NO molecules by 03 molecules. The return to a fundamental electronic state of the excited N02 molecules is made by luminous radiation, detected by the PM tube.

The model AC32M is a state-of-the-art single chamber- single photomultiplier tube design which automatically cycles between the NO and NOx modes. It was developed to meet the customer's requirement for reduced and easier maintenance with high metrology. It combines a powerful, easy-to-use interface with quality com¬ponents and design technology.
Real-time calibration graphs can be displayed during span check operation. Multi-tasking software, combined with the LCD graphic display, gives a user-friendly access to the instrument set-up, as well as the status and maintenance parameters. Real-time] synoptic, auto-diagnostic and maintenance data screens can be displayed while the instrument is operating. The new electronics allow enhanced data storage of more than one month of 15 minute averages, and total remote troubleshooting diagnostic capabilities via modem, using the analyzer's complete display and functions emulation.
Equipped with the optional ESTEL I/O analog & digital board, the AC32M can be easily interfaced with other equipment and can be operated as a stand alone unit able to store several months of data.
