One may ask, why should we bother to learn how to read a psychrometric chart? After all, we have myriad online calculators, tables, iPhone apps, etc. Most of our instruments perform the conversions as a built in feature.

At Rotronic, we aim to help you make a better measurement. The first step in making a better measurement is to understand the parameter you wish to measure.

What better way to begin to understand the various humidity parameters and their interrelations than to study the visual representation in a psychrometric chart.
