Hygrometer Calibration

The Portsmouth Naval Shipyard, under the Department of the Navy Naval Sea Systems Command, is soliciting calibration services for four Panametrics OptiSonde chilled mirror hygrometers and associated sensors through Request for Quotation N3904026Q4761. The contractor must perform NIST-traceable calibration services at multiple test points ranging from -35.00°C to 25.00°C, with calibration performed by a Commercial Calibration Activity (CCA) or Original Equipment Manufacturer (OEM) certified and accredited to recognized standards including ANSI/NCSL Z540.1, Z540.3, ISO 17025, or NAVSEA 04-4734B. Vendors must demonstrate current accreditation from bodies such as A2LA, ANAB, IAS, NVLAP, PJLA, or JNAC, and Level 3 accredited calibration per ISO/IEC 17025:2017 is the only acceptable service level. Award will be made to the vendor offering the Lowest Price Technically Acceptable solution, with evaluation based on technical acceptability, price competitiveness, and schedule adherence. The deadline for quote submission is December 10, 2025, at 08:00 AM ET, with vendors required to be registered in the System for Award Management (SAM) and submit proposals via email.

This is a full and open competition with no set-aside designation, classified under NAICS code 541380 (Testing Laboratories and Services) with a $19 million small business size standard.

The government will furnish four identical OptiSonde Hygrometer Sets valued at $11,500 each, along with associated D-2 sensors with platinum-chill mirrors and temperature sensors, all of which must be calibrated and returned with proper documentation and calibration stickers. Performance of calibration services will occur at the contractor's facility, with the calibrated equipment shipped back to Portsmouth Naval Shipyard in Kittery, Maine. Contractors must comply with the shipyard's Operations Security (OPSEC) requirements, which include strict protocols for protecting sensitive government information and restrictions on portable electronic devices and information distribution.
