SO2 Analyzer | Ametek 921

The Ametek 921 Analyzer is a single rugged SO2 gas analyzer housed in a single 19-inch rack-mounted unit. It can be integrated into CEM systems or used alone for a variety of gas monitoring applications. The design of the Model 921 without moving parts has been specially developed to enable the high sensitivity and low concentration measurements required by the latest environmental regulations.
 
The Model 921 can be configured to measure most gases that absorb UV. The optional low-range white cell provides a longer path length for measuring lower concentrations. For example, the minimum full scale for SO2 is 25 ppm, with an accuracy of 1% of full scale. The simple and robust design of the Model 921 is complemented by powerful data processing capabilities.
