Ambient Gas Monitors

Measure ammonia (NH3) concentrations in ambient air with the Thermo Scientific™ Model 17i Ammonia Analyzer. The Model 17i utilizes chemiluminescence technology for a reaction that produces a characteristic luminescence with intensity proportional to the amount of NO. Highly reliable, this analyzer provides long-term stability.

Key Features:

• Measurement of NH3 as well as NO, NO
• Unparalleled sensitivity and selectivity
• Automatic and manual modes
• Selectable time constants

Additional Information:

• While operating in the NO mode, the sample is mixed with Ozone in the reaction chamber. This reaction produces a characteristic luminescence with intensity proportional to the concentration of NO.
• In the NOx mode, the sample is passed through a molybdenum converter which reduces any NO2 in the sample to NO. This is then transported to the reaction chamber where the sample is measured as NOx (NO + NO2).
• In the third mode, the sample is passed through a stainless steel converter where both the NO2 and the NH3 are converted to NO. This is then measured as Nt (NO + NO2 + NH3).

iSeries Advantage:

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