Description
Return result.correctionFactor = (airOxygenPercent-referenceOxygenPercent)/(airOxygenPercent-measuredOxygenPercent).
Gas concentrations depend on moisture, oxygen and reference-state conventions. Removing water vapor changes the volume denominator; oxygen normalization uses a separate dilution convention. Both require compatible measurement bases.
Return result.correctionFactor = (airOxygenPercent-referenceOxygenPercent)/(airOxygenPercent-measuredOxygenPercent).
When to use this tool
Use Environmental Engineering: Stack Gas Oxygen Reference Factor when checking one explicit gas-basis correction factor.
How to use the tool and how it works
- Enter measuredOxygenPercent, referenceOxygenPercent, airOxygenPercent. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read result. Expand result to inspect the returned fields.
Require airOxygenPercent in [0,100], and nonnegative measuredOxygenPercent and referenceOxygenPercent both strictly below airOxygenPercent. Return result.correctionFactor = (airOxygenPercent-referenceOxygenPercent)/(airOxygenPercent-measuredOxygenPercent). Enter all three as percent magnitudes, such as 21 rather than 0.21.1

}Limitations and assumptions
- Apply the dimensionless factor separately to a concentration on a compatible gas basis. This tool neither chooses the reference oxygen value nor converts wet/dry or temperature/pressure bases, and it does not determine emission compliance.
- Outputs are nested inside result. Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Establish the required wet/dry, temperature, pressure and oxygen references before combining correction factors or interpreting an emissions measurement.
