The Hartford Courant, the country's oldest continuously-in-print newspaper, recently published a special section on the state’s history of innovation (“250 Years Innovation”, 28 December 2014) in which Pratt & Whitney, founded in Hartford Connecticut played a prominent part. The author noted that Pratt & Whitney “…has long been a pioneer in precision measurement systems”. From the beginning Pratt & Whitney worked to establish a commercial standard inch, accurate to several millionths of an inch then went on to produce working master copies of the few existing national length standards. Next, the company developed the Rogers-Bond Comparator, accurate to 20 micro-inches. This machine, now in the Smithsonian, was the forerunner of the famous Pratt & Whitney Standard Measuring Machine introduced in 1885. Recent variants of the Standard Measuring Machine line are still in use today.
Pratt & Whitney, founded in 1860, is a global supplier of ultra-precision Metrology instruments, inspection gauging systems, and length measuring machines. Pratt & Whitney instruments incorporate the latest in laser and sensor technology allowing for fast and accurate measurements.
