About
The names behind the logo have changed, but the products and the reputation are still going strong. CPN remains a leader in the construction and raw materials industry, providing high caliber products and continuously evolving technology.
Established in 1964, CPN changed owners in 2008 when it was purchased by InstroTek, Inc., based out of Raleigh, North Carolina. But for CPN, Concord, California remains home. The two companies working together have established a well-known powerhouse, expanding services in Concord, as well as four other fully equipped offices in Denver, Colorado; Grand Rapids, Michigan; Las Vegas, Nevada and Raleigh, North Carolina. With these five strategically located offices throughout the US and numerous international distributors, our customers are never far from our experienced and knowledgeable representatives.
CPN has been and will remain a solid competitor, whether it’s manufacturing equipment, research and design, providing gauge services, calibrations or quality parts. With InstroTek, Inc. and CPN collaborating, all of your construction and raw materials testing needs will be met and exceeded.
Testimonials
They help my staff with field fixes on minor technical issues and the new electronics and software enables us to use a simple 9V battery if the main battery pack dies on the jobsite. Even something as simple as providing wheeled cases to ease moving the gauge around jobsites is geared to the end users. I recommend them to anyone who uses nuclear gauges in the field.

Everyone at CPN has been consistently wonderful. Fantastic customer service and above and beyond what I would even expect. It is a pleasure doing business with CPN.
Corinne Stewart, Pacific Geotechnical – Morgan Hill, CA
I recommend them over other companies. The prices are competitive and the quality is great. They take on themselves the quality of their products and services beyond the given warranty time. Working with Instrotek gives me the confidence that they are there to back their product and services with a smile on their faces.
