PsyCalc

PsyCalc®, the number one desktop psychrometric calculator for over 20 years, is now available for iPhone and iPad. Its intuitive interface, flexibility and wide operating range makes it the tool of choice for tens of thousands of professionals worldwide. The rigorous calculation engine driving PsyCalc® is recognized by many engineers as the gold standard.

PsyCalc® includes screens for finding properties of a point, mixing two air streams, finding process energies between two points and setting your screen defaults.

PsyCalc® operates in I-P (inch-pound or English) units or SI (System International or metric) units. Input and output values can be set to different units providing an easy means to make conversions.

PsyCalc® is immediate. Make a change to the inputs and the outputs are updated immediately. There is no calculate button, all values are always up-to-date and valid.

Numeric inputs are entered via a numeric keypad.
