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.
