There are several versions of the HDPsyChart available to you. The Pro version is the most comprehensive version. The Standard version includes a subset of the Pro version functionality and is great for basic psych chart plotting. The OEM version is the same as the Pro version but includes your company's logo and color-scheme. We also offer the Akton version (from the acquisition of Akton Associates a while ago) that is the same as the Pro version but includes much lower and higher temperature ranges.
