The Ametek Western Research Model 900 air demand analyser was specifically designed to assist in the control of the combustion air to acid gas ratio in Claus sulphur recovery plants. Used in conjunction with the ASR 900 sampling probe, the Model 900 ensures maximum data availability for optimum operation of all sulfur recovery processes. It uses high resolution UV technology in a dual beam, multiple wavelength configuration. Resolution better than 0,02 nm is provided by high intensity, line source lamps. These sources emit at a fixed wavelength, providing great measurement stability, and emit low total power, removing the potential for sample photolysis. The high resolution enables unparalleled linearity over a wide dynamic range (less than 1% deviation over four to five orders of magnitude), which in turn leads to simple, robust data analysis. A six-position filter wheel enables one reference and five measure wavelengths.
