Using infra-red analysis is considered a more accurate method for determining the percent carbon of a
gas compared to using an oxygen probe alone. The single point oxygen probe assumes a theoretical
mixture of endothermic gas to infer the percent carbon whereas the gas analyzer will measure the exact
composition of the process gas. The percent carbon determined by the gas analyzer can then be used to
adjust the carbon percentage determined by the oxygen probe.
Chart
The Chart Display shows between 1 hour and 24 hours of process variable data on the screen and can be
scrolled back to view all of the data stored on the flash card. The vertical timelines change as the time
changes on the screen. The function buttons run along the bottom of the screen.
