Product SpecificationsMMooddeell 4422i NNOO--NNOO22--NNOOXX AAnnaallyyzzeerrChemiluminescent gas analyzer with enhanced communicationcapabilities for ambient air and source emissions monitoring Analyze • Detect • Measure • ControlTMAA cchhaannggee iiss iinn tthhee aaiirrThe industry’s new best-of-breed. Ourcustomers told us exactly what they’relooking for in a gas monitoring solution:reliability, simplicity, ease of use. Thenew iSeries platform delivers on allcounts - and then goes a step farther.The flagship product in Thermo’s newiSeries product line is the Model 42i NO-NO2-NOX analyzer. Using chemiluminescence technology,the Model 42i measures the amount ofnitrogen oxides in the air from sub-ppblevels up to 100ppm.The Model 42i is asingle Chamber, single photomultipliertube design that cycles between the NOand NOX modes. The 42i has independent outputs for NO,NO2, and Nox and each can be calibratedseparately. Dual range and Auto rangeare standards features as well. Ifrequired, the instrument can be operatedcontinuously in either the NO or NOXmodes allowing for response times of lessthan 5 seconds.Temperature and pressure correction are standard features. User settablealarm levels for concentration and for awide variety of internal diagnostics areavailable from an easy to follow menustructure.This state-of-the-art gas analyzer offersfeatures such as an ethernet port as wellas flash memory for increased data storage. Ethernet connectivity provides efficientremote access, allowing the user to down-load measurement information directlyfrom the instrument without having to beon-site.You can easily program soft-keys toallow you to jump directly to frequentlyaccessed functions, menus or screens Thelarger interface screen can display up tofive lines of measurement information.KKeeyy FFeeaattuurreess?
