AMETEK , PROCESS INSTRUMENTS A Extractive sulfur recovery tail gas analyzer The 900 ADA uses our proprietary high-resolution ultraviolet (UV) technology in a dual-beam, multiple-wavelength configuration. A resolution of better than 0.02nm is provided by high-intensity, line-source lamps. These sources emit at a fixed wavelength and provide great measurement stability. The high resolution enables unparalleled linearity over a wide dynamic range (<1% deviation over 4-5 orders of magnitude). This unit is ideally suited for extreme climates where a shelter for personnel is required or where there are constraints to mount a 'top of the pipe' (AMETEK 888) tail gas analyzer. Dual beam configuration Combined with the reference measurement, the dual-beam configuration enables low noise performance with minimal baseline and span drift. ASR 900 probe The ASR 900 probe incorporates a temperature-controlled sulfur condenser, providing sulfur vapor control at the sample point and ensuring that no plugging will occur in the sample lines and analyzer. Sample line type tail gas analyzer The sample can be delivered up to 20m (60ft) or more from sample tap to analyzer shelter, which can be located at grade level.
