Eenvoudig de vochtigheid berekenen en converteren

Met de gratis Vaisala vochtigheidscalculator kunt u verschillende vochtigheidsparameters berekenen vanuit één gegeven waarde. Eenheden kunnen binnen enkele seconden worden geconverteerd, zodat u de effecten van wisselende omgevingsvoorwaarden zoals temperatuur en druk kunt berekenen.

U kunt de volgende parameters berekenen of converteren: relatieve vochtigheid, dauwpunt/vriespunt, absolute vochtigheid, waterinhoud, mengverhouding, waterdampdruk, ppm (parts per million), natte-boltemperatuur.

De calculator is uitgevoerd in de volgende talen: Engels, Chinees, Nederlands, Duits, Fins, Frans, Japans en Portugees.

- Fixed a bug in language negotiation that resulted in "Locale not found" errors in some localization combinations.
- New Vaisala visuals.


Version 2.1 2008-04-23

- Fixed a calculation bug related to user changing ambient conditions (T, P).
  Now all values are calculated based on new ambient conditions.


Version 2.0 2008-04-08

- Wetbulb calculation added. User can insert custom psychrometer coefficients.
- All values are calculated after changes in ambient conditions (T, P, gas type).
- Maximum ambient temperature increased to +373 °C (+703 °F).
- Portuguese localization added.


Version 1.3 2007-06-28

- Fixed a bug in pressure unit conversion when converting to or from mmHg/Torr.
