DESCRIPTION
HumiCalc® software is the first of its kind to make simple work of complex humidity conversions. No more charts! No more tables! No more guess work! With its high accuracy formulas, HumiCalc® gives you the right answer every time. View data on screen or save to a file. With the multiple calculation feature, you can automatically convert an entire range of data, with selectable end points and step sizes. And you can even send the calculated data to a spreadsheet compatible data file for import into your favorite spreadsheet or graphing program. A typical calculation requires only a temperature, a pressure, and one known humidity parameter. From this minimal input, HumiCalc® computes all the final humidity values for you.
CALCULATION RANGE
Relative Humidity: ................ 0.0001 to 100.00% RH
Frost Point: .......................... -99.99 to 0.01 °C
Dew Point: ........................... -99.99 to 100.0 °C
Temperature: ...................... -99.99 to 200.0 °C *
Pressures: ........................... Near 0 to 5000 psia *
* Vapor Pressure and enhancement factor formulas for pressures greater than 1500 psia and temperatures greater than 100 °C are based on extrapolated data.
SPECIFICATIONS
HumiCalc® requires Microsoft Windows 95, 98, NT4.0, 2000 or XP.
