1986–2026: Celebrating Four Decades of Reliable & Accurate Measurement Solutions
GP:50 proudly announces its 40-year anniversary, marking four decades of delivering precision, durability, and performance to industries worldwide.
Founded in 1986 in Grand Island, New York by Donald J. Less, GP:50 began with a focused commitment to designing high-quality pressure transducers for demanding industrial applications. Over the past four decades, that commitment has driven steady growth, expanding both its product portfolio and the industries it serves. Today, GP:50 is a globally recognized manufacturer supporting critical applications across aerospace, automotive testing, oil and gas, subsea, water and wastewater, medical, and industrial automation.
As demand for high-performance sensing solutions increased, GP:50 expanded its manufacturing capabilities to support more advanced and specialized applications. The addition of separate production, warehouse, service, and other bays was followed by a dedicated aerospace manufacturing bay in 2019, marking a significant milestone in the company’s ability to engineer solutions for the rigorous and specialized demands of the aerospace industry. These expansions grew the company’s footprint from its original roughly 10,000 square feet to nearly 60,000 square feet today, enabling the production of sensors for highly regulated and mission-critical environments.
From its early operations to today’s expanded facility, this growth reflects a continued investment in engineering, manufacturing, and the ability to meet evolving industry demands.
Throughout its growth, GP:50 has maintained a strong commitment to quality and compliance. The company operates as an AS9100D and ISO 9001:2015 certified manufacturer and maintains NIST 800-171 compliance, reflecting its ability to meet stringent industry and government requirements.
As the company evolved, it built its reputation on solving complex application challenges with precision-engineered solutions tailored to exact customer requirements. This ability to deliver both standard and highly customized sensors, combined with responsive engineering support and short lead times, has remained a defining strength throughout its history.
For 40 years, GP:50 has built its reputation on a simple standard: Reliable & Accurate. Not claimed. Proven. Every product is engineered to perform in the harshest environments, from cryogenic conditions to high-temperature, high-pressure, and corrosive applications where failure is not an option.
“Reaching 40 years is more than a milestone. It is proof,” said a company spokesperson. “Proof that our products perform. Proof of our commitment. Proof that our customers trust us. And proof that when measurement matters, GP:50 delivers.”
From oilfields and test labs to deep subsea environments and aerospace applications, GP:50 sensors are designed, manufactured, and tested to withstand the real-world demands customers face every day. That same performance is trusted on current missions such as Artemis II. As industries continue to push boundaries, GP:50 remains committed to advancing sensing technology that meets those challenges head-on.
As the company looks to the future, GP:50 will continue investing in innovation, expanding capabilities, and strengthening partnerships while staying grounded in the performance standards that defined its first 40 years.
