Now available for rent, the Thermo Ozone analyzer, model 49i utilizes uv photometric technology to measures the amount of ozone in the air from ppb levels up to 200ppm.The Model 49i 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. 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 gas analyzer 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 from the instrument without having to be on-site. You can easily program short-cut keys to allow you to jump directly to frequently accessed functions, menus or screens The larger interface screen can display measurement information and status, while viewing menu and operational screens.
