The SPC Express family of Quality Control software consists of three main products - SPC Express for DOS, AutoTrans for DOS, and SPC Express for Windows.   The DOS versions are listed here for historical reference only and are no longer being sold.   SPC Express was created over 25 years ago and has gained a reputation for being the easiest-to-use SPC program ever available.   SPC Express was designed to run in an office or out on the shop floor and can receive sample data from either electronic gages or the keyboard and charts up to 100 characteristics at a time.

In order to assist you in deciding which product is right for you, we have put together a table comparing the various programs. Click on one of the titles for more information on that product.
