Our History

 

Our first psychrometric chart was produced in 1987 for an Oklahoma University Mechanical Engineering course. Perfect gas approximations were written into Quick Basic to calculate the X-Y data points and manually plotted. The resultant chart can be seen in the photo taken to the right.

By 1992, psychrometrics had become such a passion that we continued our efforts to produce the best charts possible. Microsoft continued to expand the capabilities of their spreadsheet software known as Excel.  Macro, functions and formulae sophistications capabilities expanded, and as they did, we began to build our first truly electronic psychrometric charts.

In 1993, we produced stand alone psychrometric calculators written in DOS Compiler Basic using the 1993 ASHRAE Fundamental coefficients and the perfect gas approximations. 

 

In 1995, we began using a new Microsoft platform called Visual Basic 3.0. Visual Basic allowed us to combine our Excel charts and stand alone DOS psychrometric calculators into one product.
