Ametek 900 Tail Gas-Air Demand Analyzer

Ametek 900 Tail Gas-Air Demand Analyzer

The Ametek 900 Tail Gas-Air Demand Analyzer was specifically designed to meet the more demanding analytical requirements of new processes. Used in conjunction with the ASR 900 sampling probe, which provides trouble-free sampling, the Ametek 900 Tail Gas-Air Demand Analyzer ensures maximum data availability for optimum operation of all sulfur recovery processes.

Using high-resolution ultraviolet (UV) technology in a dual-beam, multiple-wavelength configuration, the Ametek 900 Tail Gas-Air Demand Analyzer is specifically designed to meet the demanding analytical requirements of modern sulfur recovery processes.

Capable of measuring up to four species simultaneously, this air demand analyzer is uniquely capable of monitoring off-ratio applications, providing accurate chemical concentration data over wide dynamic ranges.

High-intensity, line-source lamps provide a resolution better than 0.02nm, and great measurement stability. The high-resolution enables excellent linearity over a wide dynamic range.

Designed for extreme climates where a personnel shelter is required, or where there are constraints to mount a ‘top of the pipe’ analyzer, the Ametek 900 Tail Gas-Air Demand Analyzer is ideal for use in the hydrocarbon processing industry.

the Future of Industrial Process Analytics: The OMA Process Analyzer

At Analytical Solutions and Products, we are constantly seeking to innovate and provide our clients with the most advanced solutions in industrial process analytics. This is why we have chosen the OMA Process Analyzer by Applied Analytics as the new standard, replacing this Ametek process gas analyzer. We firmly believe that the OMA Process Analyzer represents the future of industrial process analytics. Its advanced technology and robust design align perfectly with our commitment to innovation and excellence in the field. By integrating the OMA Process Analyzer into your operations, you are not just upgrading your equipment; you are stepping into the future of industrial analysis.

Ametek 900 Tail Gas-Air Demand Analyzer DUAL-BEAM CONFIGURATION

Combined with a reference measurement, the dual-beam UV configuration enables the Ametek 900 Tail Gas-Air Demand Analyzer to operate with low-noise performance, providing minimal baseline and span drift.


The ASR900 advanced sulfur reduction sampling probe uses a temperature-controlled sulfur condenser, providing sulfur vapor control at the sample point. This ensures no plugging will occur in the sample lines and analyzer.


The sample can be delivered up to 20m (60ft) or more from sample tap to the analyzer shelter, which can be located at grade level.
