PRODUCT DESCRIPTION
The Thermo Scientific range of iSeries gas analysers have by far and away the least requirement for maintenance of any gas analysers on the market today and are built for reliable continuous duty field gas detection.
The Model 42i TL uses chemiluminescence technology to measure the amount of nitrogen oxides in the air from sub-ppb levels up to 1000ppm. The Model 42i is a single chamber, single photomultiplier tube design that cycles between the NO, NOX and zero modes. The 42i has independent outputs for NO, NO2 and NOX and each can be calibrated separately. Dual range and Auto range are standard features as well.
This state-of-the-art gas analyser offers features such as an Ethernet port as well as flash memory for increased data storage. Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly from the instrument without having to be on-site.
You can easily program soft-keys to allow you to jump directly to frequently accessed functions, menus or screens and the larger interface screen can display up to five lines of measurement information.
