The Model 49i Ozone Analyser is a dual cell photometer, the concept adopted by the NIST for the national ozone standard. Dual range and auto range are standard features in this instrument. Because the instrument has both sample and reference flowing at the same time a response time of 20 seconds can be achieved.
Temperature and pressure correction are standard features on the Model 49i Ozone Analyser. User settable alarm levels for concentration and for a wide variety of internal diagnostics are available from an easy to follow menu structure.
This state-of-the-art Model 49i Ozone Analyser offers features such as an ethernet port as well as flash memory for increased data storage and field upgradability. Ethernet connectivity provides efficient remote access, allowing the user to download measurement information directly form the instrument without having to be on-site.
With the Model 49i Ozone Analyser you can easily program soft-keys to allow you to jump directly to frequently accessed functions, menus or screen. The larger interface screen can display measurement information and status, while viewing menu and operational screens.
