How it measures

Measurement Principle

The planned Model 800RS platform continuously measures H₂S and SO₂ in conditioned sulfur recovery tail gas. It calculates the H₂S-to-SO₂ ratio and can provide an air-demand or ratio-control signal. Final optical detector architecture, ranges, and validated response performance will be stated in the approved product datasheet.
