About the company
JH Acquisition, LLC, doing business as En-Sci, manufactures and supplies specialized atmospheric monitoring instrumentation—principally electrochemical concentration cell ozonesondes, cryogenic frostpoint hygrometers, and related radiosondes—to NOAA and NASA on a prime-contractor basis through full-and-open purchase orders, with no subcontract activity. En-Sci is a self-certified small disadvantaged business based in Westminster, Colorado, and a limited liability company structured as a for-profit organization.
En-Sci operates exclusively as a prime contractor (100% of recent awards) across a narrow customer base: NOAA's National Oceanic and Atmospheric Administration accounts for 36 awards valued at $3 million combined potential value, while NASA's Shared Services Center places 27 awards valued at $1.5 million, and NASA's Langley Research Center has placed one award valued at $28,000. The two rankings coincide — NOAA and NASA together represent 100% of En-Sci's federal revenue. All awards are unset-aside, commercial purchases issued under FAR Parts 12 and 13 as firm fixed-price purchase orders. NOAA and NASA award En-Sci sole-source contracts under FAR 13.106-1(b)(1)(i), justifying exclusivity based on En-Sci's status as the sole manufacturer of electrochemical concentration cell ozonesondes compatible with each agency's existing atmospheric monitoring networks and multi-decadal data continuity requirements.
Recent contract work illustrates the portfolio: a $59,999.89 NOAA purchase order (awarded August 26, 2026, completing November 26, 2026) for scientific instruments supporting GCOS GRUAN upper air monitoring observation sites; a $325,539.54 NASA Shared Services Center purchase order (awarded July 21, 2026, completing September 30, 2026) for 2026 9-station SHADOZ ozonesonde network equipment; and a $242,599.50 NOAA purchase order (awarded February 20, 2025, completing May 14, 2025) for 2Z-V7 ozonesondes measuring high-resolution vertical ozone profiles. En-Sci's instrumentation underpins NOAA's Global Climate Observing System Reference Upper-Air Network (GCOS GRUAN) and the Southern Hemisphere ADditional OZonesonde (SHADOZ) project, with deployed systems across Ecuador, Hawaii, Samoa, Fiji, Vietnam, Kenya, Costa Rica, Ascension Island, and other international atmospheric research stations.
Activity has been uneven over the past five years: eight awards in 2022, declining to four in 2024, then recovering to seven in 2025 and two in 2026 year-to-date. Only one award (combined potential value $60,000) faces ultimate completion inside the next twenty-four months. En-Sci's footprint concentrates on analytical laboratory instrument manufacturing (42 awards) and other measuring and controlling device manufacturing (22 awards), with 36 awards classified under the meteorological instruments and apparatus PSC code. Total combined potential value across all 64 awards is $4.5 million, with 100% obligated.
