PP Systems was established in 1984 by Dr. Keith J. Parkinson, whose work on the measurement of photosynthesis at Rothamsted Experimental Station led to the development of one of the first portable photosynthesis systems ever produced.

In 1993, PP Systems, Inc. was established in the United States to focus on sales and support for all North American customers. Over the last 35+ years, we have developed into a highly specialized team of technical experts in the design and manufacture of a wide range of scientific instrumentation including the popular CIRAS series of Portable Photosynthesis Systems, CO2 and H2O gas analyzers, vegetation, and remote sensing instrumentation.

Today, all business operations are handled through our U.S. headquarters which features our comprehensive design and development facility, service, production, and full calibration and testing capability. Each instrument must meet PP Systems’ strict quality control/assurance protocols before it can leave the facility. PP Systems is based in the Boston North Technology Park (BNTP) which is located in Amesbury, MA (USA) which is a short 40-minute drive from Boston.
