Ametek Model 921 Standard Level SO2 Analyzer
The Ametek Model 921 SO2 analyzer uses proprietary high-resolution ultraviolet fluorescence technology in a dual beam, dual wavelength configuration. This technology minimizes interference and quench effects that are typically found in UV based instruments. The analyzer is microprocessor controlled and incorporates a standard sample cell for typical concentration measurements.

Ranges	0-50 to 0-5000 ppm (user defined)
Detection Method	Ultraviolet Fluorescence
Sample Gas Input	1/4-inch Tube; 1 to 2 lpm
Analog Outputs	0-1, 5, 10 Vdc, 4-20mA (please specify if desired)
Power Requirement	110 VAC/60 Hz
Shipping Dim/Wt	32x25x14 – 64 lbs

Ametek Model 921 High Level SO2 Analyzer
The Ametek Model 921 SO2 analyzer uses proprietary high-resolution ultraviolet fluorescence technology in a dual beam, dual wavelength configuration. This technology minimizes interference and quench effects that are typically found in UV based instruments. The analyzer is microprocessor controlled and incorporates a “mid level” sample cell for high concentration measurements.

Ranges	0-250 to 0-25,000 ppm (user defined)
Detection Method	Ultraviolet Fluorescence
Sample Gas Input	1/4-inch Tube; 1 to 2 lpm
Analog Outputs	0-1, 5, 10 Vdc; 4-20mA (please specify if desired)
Power Requirement	110 VAC/60 Hz
Shipping Dim/Wt	32x25x14 – 64 lbs
