Heritage of Innovation. Future of Science

For over five decades, Princeton Applied Research has been at the forefront of electrochemical research instrumentation. Our solutions are trusted worldwide for applications in corrosion science, energy storage, nanotechnology, sensors, and surface imaging. 

We combine innovation, performance, and value to deliver instruments that meet diverse research needs. With an extensive product portfolio and one of the most experienced technical support teams in the industry, we help laboratories select the right system for today and the future. Founded in 1961 by scientists from Princeton University, we pioneered the first commercial potentiostat in 1968. Today, as part of AMETEK, we continue to set benchmarks with advanced products like the PARSTAT, VersaSTAT series and Scanning Electrochemical Microscopy Princeton Applied Research remains committed to driving electrochemical research forward through cutting-edge technology and exceptional service.

SIGNAL RECOVERY, part of AMETEK Advanced Measurement Technology, designs and manufactures precision instruments including lock-in amplifiers, signal averagers, amplifiers, light choppers, multiplexers, and specialized counters. Our roots trace back to Princeton Applied Research—the inventors of the lock-in amplifier—giving us unmatched expertise in solving complex measurement challenges for researchers worldwide. 

Over the years, our products have carried names like EG&G, Brookdeal Electronics, and PerkinElmer Instruments. Since 2001, we’ve proudly operated under the SIGNAL RECOVERY brand, continuing a legacy of innovation and reliability.

Solartron began in 1947 when engineers E. R. Ponsford and L. B. Copestick started subcontract work for the UK’s General Post Office and Admiralty Research Laboratory. By 1948, they registered the Solartron name and introduced innovative instruments like pulse generators and oscilloscopes.

Through decades of growth, Solartron pioneered technologies in measurement and simulation, later focusing on electrochemical analysis. After joining AMETEK in 2005, Solartron Analytical consolidated development, production, and service at its Farnborough facility. Today, we continue to build on this legacy, delivering advanced battery cycler & analyzers, frequency response analyzers and electrochemical solutions to researchers worldwide.
