Using chemiluminescence technology, the Model 42i measures the amount of nitrogen oxides in the air from sub-ppb levels up to 100ppm.The Model 42i is a single Chamber, single photomultiplier tube design that cycles between the NO and NOX modes. The 42i 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 less than 5 seconds.

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.

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 The larger interface screen can display up to five lines of measurement information while primary screen remains visible.

Key Features:

- Ethernet connectivity for efficient remote access
- Enhanced user interface with one button programming and large display screen
- Flash memory for increased data storage
- Enhanced electronics design optimizes product commonality
