About us

PQ Systems is a privately-held company headquartered in Dayton, OH, with a regional office in the United Kingdom and distributors in Europe, Central and South America, Africa, and Asia.

For more than 30 years, the company has been providing solutions to help organizations implement quality improvement programs and demonstrate proof of their quality performance.

Our original software product, SQCpack statistical process control software, was developed by Sean T. Cleary, Ph.D., now a professor of mathematics at CCNY, in 1982. Since that time, SQCpack statistical process control software licenses have been installed in more than 60 countries, and the PQ Systems software suite has expanded to include gage management and more.

Our quality control software solutions include statistical process control (SPC), gage management, measurement systems analysis, quality concepts, training materials, and more.

In addition to SPC and gage management applications and other quality control solutions, PQ Systems offers a variety of training opportunities, including public seminars, on-site training, and web-based instruction.
