Free Dewpoint Calculator
For Trace Moisture Measurements in Gases & Air
The dewpoint calculator will convert between various units of measurement. To use, simply enter a number in either one of the two dewpoint values, selecting appropriate units, or one of the four absolute values before pressing the calculate button. ‘Line Pressure’ and ‘Gas Type’ are only required as inputs if the ‘dewpoint at line pressure’ or ‘ppm(w)’ are to be calculated. You can choose from seven common gases or enter known moleculer weight and line pressure units can be changed to bara, barg, psia, psig, KPa and MPa.
Please press the “Reset” button after each calculation to clear the fields.
