About the company
RH Systems LLC, a veteran-owned small business manufacturer based in Gilbert, Arizona, supplies precision temperature and humidity generators, chilled mirror hygrometers, pressure sensors, and calibration services to federal agencies as a prime contractor on a full-and-open basis, with no set-aside designations across its award footprint. The company operates as a for-profit limited liability corporation structured as a manufacturer of goods; it competes exclusively on prime awards (100% of recent work) with no subcontractor presence.
RH Systems holds a significant five-year indefinite delivery contract with the Department of the Navy Naval Sea Systems Command valued at up to $3.74 million to supply temperature and humidity generators in support of research, development, test, and evaluation activities. Recent delivery orders under this vehicle include a $1.495 million award issued June 22, 2023, for temperature humidity generators with completion in June 2024, and a $448.650 million award issued January 30, 2024, also for temperature humidity generator delivery. Beyond the Naval Sea Systems Command vehicle, RH Systems has executed additional task orders for Mensor pressure sensors ($57.270 thousand, June 2023) and systems chamber exhaust kit parts ($12.827 thousand, May 2022). The company's customer concentration is pronounced: Naval Sea Systems Command anchors 8 awards representing $6.8 million of the combined $12.9 million potential value across the portfolio, while the Air Force Materiel Command (2 awards, $5.4 million potential value) drives a second-order concentration spike. The top five funding agencies account for 73% of all awards. NOAA and the National Institute of Standards and Technology account for 7 and 5 awards respectively but carry minimal dollar values ($162 thousand and $221 thousand combined), indicating a pattern of smaller calibration and repair tasks alongside the larger Navy equipment delivery work.
Recent capability examples include a $95 thousand sole-source purchase order from Air Force Materiel Command (March 2024) for CGS-240 humidity generator firmware and software upgrades; a $68.425 thousand NIST purchase order (September 2026) for two Duet chilled mirror hygrometers supporting laboratory environmental monitoring; and a $20 thousand USAF Europe and Africa repair order (October 2023) for CGS-240 humidity generator replacement and restoration at Aviano Air Base. Work spans maintenance, repair, and calibration services with the Naval Air Warfare Center and Air Force facilities, plus equipment calibration at NOAA's National Data Buoy Center and Department of Energy sites. Award activity has been modest but consistent: 3 awards per year in 2022 and 2023, accelerating to 7 in 2024 before declining to 2 in both 2025 and 2026. Only $73 thousand in potential value completes within the next twenty-four months, limiting near-term recompete pressure. The company's NAICS footprint concentrates on instruments and related products manufacturing for industrial process variables (19 awards) and electronic precision equipment repair and maintenance (5 awards), with primary PSC coding in pressure, temperature, and humidity measuring and controlling instruments (16 awards).
