湿度计算表

​​​湿度计算与换算更加方便 – 在线、离线及移动过程中​​​​​​

维萨拉免费湿度计算表可让您能够根据一个已知值计算出多个湿度参数。单位换算顷刻完成,方便查看温度和压力等变动环境条件的影响。湿度计算让复杂的人工计算和换算一去不返。

该工具包括对以下参数的计算和换算:*相对湿度、*露点/霜点、*绝对湿度、*水含量、*混合比、*水蒸气压力、*体积比、*湿球温度、*焓值、*比容、*密度。

适用于PC机或手机等各种设备,即可在线也可离线使用的全新用户界面。

可选用八种语言:*英文、*中文、*荷兰文、*芬兰文、*法文、*德文、*日文和*葡萄牙文。​

​​Version history of the PC application

  Version 3.1 2014-02-08
- Fixed a bug in the pressure unit (psig) conversion.
- New rounding function to improve calculation accuracy at extreme conditions.
- Minor user interface improvements.

Version 3.0 2013-08-27
- Entirely new calculation engine.
- New calculated parameters: enthalpy, specific volume, density.
- Replaced Basic and Advanced tabs with a customizable user interface.
End user can now decide which measurement parameters are shown on the screen.

Version 2.2 2009-11-23
- Fixed a calculation bug related to user changing both ambient conditions (T, P) at the same time. Now re-calculation happens immediately after condition has been changed.
- 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.

Version 1.2 2007-04-05
- Improved accuracy of vapor pressure calculation in high temperatures.

Version 1.1.1 2007-02-01
- Fixed a calculation bug related to using custom gases.

Version 1.1 2007-01-15
- Comma can be used as decimal separator in addition to full stop.
- Improved calculation formula for natural gas in high pressures (above 40 bar).
- Print button introduced. Use to print the whole calculator screen.
- Copy values button introduced. Use to copy/paste calculated values to other programs, e.g. Microsoft Excel.
- Switching from Basic to Advanced mode does not reset the calculation.
- Input error messages are displayed in selected units. E.g. Temperature in Celsius or Fahrenheit.​​​​​​​​
