Sensor Package - pH Sensors, Conductivity Sensors, Dissolved Oxygen Sensors, Cables, Double Flow Cells, Single Flow Cells

NASA's National Aeronautics and Space Administration Shared Services Center (NSSC) has issued a Special Notice for the procurement of sensor equipment including pH sensors, conductivity sensors, dissolved oxygen sensors, cables, double flow cells, and single flow cells. The agency intends to award a sole source contract to Hamilton Company of Reno, Nevada, under the authority of FAR 13.106-1(b)(1)(i), having determined that Hamilton Company is the sole provider of these specific sensor components. Performance will be located at NASA's Marshall Space Flight Center (MSFC), and the procurement will utilize commercial item acquisition procedures under FAR Parts 12 and 13. The contract opportunity falls under NAICS code 334516 for Analytical Laboratory Instrument Manufacturing. The procurement will be managed by NASA/NSSC as the procuring center for this acquisition effort.

The primary purpose of this Special Notice is to provide other organizations an opportunity to demonstrate their capabilities and qualifications to perform this work, potentially challenging the sole source determination. Interested parties must submit written responses demonstrating their qualifications no later than 9:00 a.m. Central Standard Time on July 10, 2025, to the designated points of contact Monica D. Wilson or Shari Trigg. Oral communications are not acceptable for this notice, and all submissions will be evaluated solely to determine whether the procurement should be conducted on a competitive basis rather than sole source. The government retains full discretion in deciding whether to proceed with competitive procurement based on the responses received. Organizations responding must be capable of providing the specialized sensor equipment and related components required for NASA's scientific instrumentation needs.
