PRODUCT SPECIFICATIONS Thermo Scientific Model 42i NO-NO2-NOx Chemiluminescent Gas Analyzer The Thermo Scientific™ Model 42i NO-NO2-NOx Analyzer utilizes chemiluminescence technology to measure the amount of nitrogen oxides in the air from sub-ppb levels up to 100ppm. Features • Ethernet connectivity for efficient remote access • Enhanced user interface with one button programming and large display screen • Flash memory for increased data storage and user downloadable software • Enhanced electronics design optimizes product commonality Introduction The Thermo Scientific Model 42i Analyzer is a single chamber, single photomultiplier tube design that cycles between the NO and NOx modes. less than five seconds. Temperature Ethernet connectivity provides efficient and pressure correction are standard remote access, allowing the user to features. User settable alarm levels for download measurement information concentration and for a wide variety of directly from the instrument without internal diagnostics are available from an easy to follow menu structure. Easily programmable short cut keys allow This state-of-the-art gas analyzer you to jump directly to frequently accessed offers features such as an Ethernet port functions, menus or screens. The larger as well as flash memory for increased interface screen can display up to five lines data storage. of measurement information while the primary screen remains visible. The 42i Analyzer has independent outputs for NO, NO2 and NOx and each can be calibrated separately. Dual range and auto range are standards features as well. If required, the instrument can be operated continuously in either the NO or NOx modes allowing for response times of Thermo Scientific™ Model 42i NO-NO2-NOX
