YSI, INC

YSI, INC specializes in the design, repair, and upgrade of high-precision analytical laboratory instruments, with deep expertise in oceanographic and environmental sensing systems. The company focuses on Aanderaa Optode sensors and Seaguard instrumentation, performing field-critical repairs and technology upgrades to meet evolving scientific standards, including transitioning first-generation Seaguard units to Seaguard II specifications. Their technical capabilities encompass sensor calibration, analog and digital signal conditioning, low-power embedded systems, and environmental hardening for extreme polar conditions. YSI’s unique specialization lies in maintaining legacy oceanographic platforms while integrating modern sensor technologies, ensuring data continuity and reliability in remote, high-stakes deployments such as Arctic and Antarctic research missions. The contractor has established a consistent working relationship with the Department of Commerce, delivering mission-critical instrumentation services that support NOAA and other scientific divisions engaged in polar climate monitoring and oceanographic data collection. Their engagements reflect a pattern of long-term technical support rather than one-time procurement, indicating trusted partnership in sustaining complex, field-deployed sensor systems. YSI operates primarily within NAICS 334516, which encompasses the manufacturing and modification of analytical laboratory instruments used in environmental and marine science. Their market positioning centers on the niche segment of oceanographic instrumentation lifecycle management—bridging the gap between legacy hardware and next-generation sensing standards. This vertical specialization serves federal research agencies requiring robust, field-proven instrumentation for extreme environments. YSI, INC is a small business structured as a 2L entity, headquartered in Saint Petersburg, Florida. While no formal government certifications are currently listed, the company’s technical track record demonstrates compliance with rigorous environmental and performance standards required for polar operations. Their geographic presence and operational focus position them as a specialized provider for federal science and environmental monitoring programs reliant on precision marine instrumentation.
