This is a Justification for Sole Source (Simplified Procedures) document issued by the Navy Region Mid-Atlantic contracting office for Purchase Request/Document number 1301383641, dated 29 July 2026.

The procurement seeks the replacement of four (4) PortaCount Model 8048-T Respirator Fit Testing Machines for Region Safety, with an estimated total cost of $57,481.77 and a required delivery date of 30 days from contract award. The sole source is TSI Incorporated, located at 500 Cardigan Road, Shoreview, Minnesota 55126, with CAGE Code 24575, and the requisitioned supply falls under CAGE Code 24575. The justification restricts competition to TSI Inc. based on three primary factors: (1) compatibility requirements—the PortaCount is a highly specialized industry standard quantitative respirator fit testing machine that must interface seamlessly with existing systems, and no other commercially available equipment meets the technical and regulatory mission requirements; (2) patent and proprietary data restrictions—TSI Inc. is the sole developer, manufacturer, and patent holder of the condensation nuclei counter (CNC) technology required for quantitative respirator fit testing down to N95 protocols without external aerosol chambers, holding exclusive patents including US Patent No. 6,125,845; and (3) direct replacement status—these machines are replacement units for current equipment reaching the end of functional life. The contracting officer determined that the circumstances justifying only one source are reasonably available and approved the sole source procurement.
