About RH Systems LLC
RH Systems LLC, a veteran-owned small-business manufacturer of temperature and humidity generators and calibration instruments based in Gilbert, Arizona, operates as a prime contractor (100% of recent awards) selling specialized environmental control equipment and metrology services to federal research, development, test, and evaluation programs across the Department of the Navy, Department of the Air Force, and civilian agencies including the National Oceanic and Atmospheric Administration and the National Institute of Standards and Technology. RH Systems competes exclusively on full-and-open (non-set-aside) basis despite its veteran-owned designation.
RH Systems' capability footprint centers on precision humidity generators, temperature-and-humidity environmental simulators, and calibration services for hygrometers and related instruments. The company manufactures the CGS-240 humidity generator, a sole-source standard for Air Force humidity calibration work, and holds a five-year Indefinite Delivery Contract with Naval Sea Systems Command (NAVSEA) valued up to $3.738 million to supply temperature and humidity generators for naval test and evaluation. Representative prime work includes a $1.495 million delivery order from NAVSEA (awarded June 2023) for temperature-humidity generators, a $95,000 Air Force Materiel Command purchase order (March 2024) for CGS-240 humidity generator software and firmware upgrades on a sole-source basis, an $18,500 Air Mobility Command repair and calibration contract (September 2024) for CGS-240 relative humidity systems at Travis Air Force Base, and multiple NOAA calibration purchase orders for hygrometer work at the National Data Buoy Center ranging from $3,685 to $7,070.
Customer concentration is marked: NAVSEA accounts for 8 awards and $6.8 million of the combined potential value — roughly 53% of the $12.8 million total portfolio — making it the anchor customer by far. The Department of the Air Force Materiel Command places the second-largest dollar value with 2 awards totaling $5.4 million, while NOAA (7 awards, $162 thousand) and the National Institute of Standards and Technology (4 awards, $152 thousand) lead by award count but with smaller individual values. The gap between NAVSEA's dominance by dollars and its lower ranking by pure count reflects the large delivery-order scale of its anchor IDC; the top five customers represent 99% of combined potential value.
RH Systems holds one named parent vehicle, the NAVSEA Indefinite Delivery Contract N6426720D0040, under which four task orders have been placed worth $3 million combined potential value. The company operates as a pure prime contractor with no recorded subcontract work in the source data. Activity has grown from three awards per year in 2022–2023 to seven in 2024, but has slowed to two in 2025 and one in 2026, suggesting execution against large delivery orders rather than new prime awards. One award (combined potential value $4 thousand) reaches completion inside the next twenty-four months, placing minimal near-term recompete exposure, though the large NAVSEA IDC itself will require renewal.
