About Us


Our Story

In the late 1960s, Calibration Services began as R.H. Forney Calibration Services, located in New Castle, PA. During these early years, the Company’s main thrust was the calibration and servicing of Forney Testing Equipment. By 1974, William (Bill) W. Stump, Jr. joined the Company, becoming partners with Russell Forney, Jr., the owner at that time.

As the Company continued to flourish, its name was changed in 1981 to what it’s known as today, Calibration Services, Incorporated (CSI). By then, Bill had been working as a part-time technician for the Company since 1977, transitioning to a full-time calibration technician in 1982. At this time, CSI purchased its first load call system, utilizing new innovations to calibrate physical strength testing machines. This was a significant advancement for the calibration industry, and just as it still is today, CSI was on the leading edge of technology.

In 1983, William W. Stump Jr. and his wife Martha Stump purchased the shares of Russell H. Forney Jr. and took over the business. With the increasing customer demand, the Company soon outgrew its operations in New Castle and relocated to Edinburg, PA, in November 1984. At this new location, an in-house laboratory was added, complete with precision pressure standards, permitting technicians to calibrate equipment and repair instrumentation at the facility. To expand services and have more room for the growing organization, in 1992, CSI relocated to its current location in Emlenton, PA.

After working alongside his father for nearly 20 years, Bill and his wife Jameen purchased the Company. Since then, CSI has significantly increased its scope of calibration, encountered new markets, and has grown its servicing areas to over 14 states, the Caribbean (U.S. Territories), and other locations. CSI obtained ISO 17025/90023 accreditation for calibration in March 2002.

CSI is a proud locally-owned and family-operated business, employing a team of highly-trained technicians and an office staff who is 100% dedicated to being your Partner in Precision.
