ABOUT US
The Clinton Instrument Company was founded in 1952 by Henry H. Clinton, inventor of the patented 3 kHz High-Frequency Sine Wave design that revolutionized spark testing methods for wire and cable insulation. More than 70 years later, that spirit of innovation continues to drive everything we do.
We are an engineering and manufacturing company specializing in high-voltage quality control and pinhole detection equipment for the wire and cable, plastics, and related manufacturing industries. A pioneer in spark testing and pinhole detection technology, Clinton Instrument Company remains at the forefront of research, development, and application engineering. Over seven decades of experience have resulted in numerous patented designs developed to meet the unique testing requirements of manufacturers around the world.
We help customers develop testing solutions quickly and cost-effectively, often for applications where standard equipment is not sufficient. Given our extensive experience, we have likely tested the product before. This allows us to provide practical solutions without a lengthy learning curve. Our size and flexibility also enable us to customize and configure systems to meet the changing demands of modern manufacturing.
In addition to manufacturing new equipment, Clinton Instrument provides factory repair services, technical support, and long-term product assistance for the systems we build. Our engineering and service teams work closely with customers to troubleshoot issues, perform repairs, implement upgrades, and help extend the operational life of critical testing equipment.
From our facility in the shoreline town of Clinton, Connecticut, USA, we design and manufacture all products in-house, maintaining direct access between our customers and the engineers and technicians who support them. This close integration of engineering, manufacturing, and service allows us to apply decades of expertise and a deep library of proven solutions to even the most demanding high-voltage testing and pinhole detection applications.
