Sentec, Inc.

Sentec, Inc., a self-certified small disadvantaged business based in Lincoln, Rhode Island, manufactures transcutaneous blood-gas monitoring systems, CO2 monitors, respiratory airway clearance equipment, and related medical device consumables for the Department of Veterans Affairs, Defense Health Agency, and civilian research institutions as a prime contractor across 29 firm-fixed-price purchase orders totaling $1.8 million in combined potential value.

Sentec is a Subchapter S corporation operating in Surgical and Medical Instrument Manufacturing (NAICS 334510) and Electromedical and Electrotherapeutic Apparatus Manufacturing (NAICS 334517), with headquarters and manufacturing performed at its Lincoln, Rhode Island facility. The company competes exclusively in full-and-open solicitations; no set-aside designations appear across the prime awards, though the source documents self-certification as a small disadvantaged business. The vendor manufactures proprietary equipment rather than distributing third-party products — core product lines include the Sentec Digital Monitoring System (with V-Sign Sensor Technology and Smart Cal-Mem calibration technology), tCOM+ Hospital monitors, IPV1 airway clearance equipment, and volumetric diffusive respirators.

Customer concentration clusters heavily within VA Veterans Integrated Service Networks. The top five VA VISNs by award count account for 59% of awards: VISN 10 leads with six awards ($189 thousand combined value), followed by VISN 21 (four awards, $299 thousand), VISN 19 (three awards, $118 thousand), VISN 4 and VISN 8 (two awards each). By dollar value, however, the Defense Health Agency anchors the portfolio with two awards ($594 thousand combined value), followed by VA VISN 21 ($299 thousand) and VA VISN 10 ($189 thousand). The 76% concentration across five customers reflects Sentec's specialized role as the sole qualified manufacturer of transcutaneous monitoring systems within VA clinical workflows; multiple awards cite sole-source justification based on proprietary sensor technology and existing facility infrastructure compatibility.

Representative prime awards include a $500.75 thousand Defense Health Agency purchase order (September 2025) for eight volumetric diffusive respirators with monitoring integration for Brooke Army Medical Center at Fort Sam Houston, Texas; a $138 thousand VA VISN 21 award (July 2025) for IPV1 airway clearance equipment and delivery services; a $93.17 thousand Defense Health Agency purchase order (June 2023) for Sentec Digital Monitoring Systems serving Naval Medical Center San Diego's Neonatal Intensive Care Unit; and a $76.31 thousand National Institute on Drug Abuse award (September 2025) for digital monitoring systems used in sleep labs and neonatal settings. Additional active awards span VA VISN 5, VISN 8, and VISN 17 for CO2 monitors, respiratory equipment bundles, and sensors carrying values between $16.6 thousand and $76.3 thousand per order.

Activity has accelerated recently — two awards in 2022, six in 2023, two in 2024, five in 2025, and eight through late September 2026 — with four awards (combined potential value $218 thousand) reaching ultimate completion within the next twenty-four months and presenting recompete exposure. All 29 awards are prime contracts with zero subcontract footprint; Sentec does not report as a subcontractor on larger primes. The vendor holds no parent IDIQ, GWAC, or BPA seat; all awards are direct purchase orders issued through simplified acquisition procedures or sole-source justifications tied to Sentec's proprietary manufacturing capability.
