NIGP 46522: Diagnostic Equipment, Computerized: Plethysmographs, Spirometers, etc.

NIGP 46522 Diagnostic Equipment, Computerized: Plethysmographs, Spirometers, Etc., an Item code, encompasses respiratory diagnostic and pulmonary-function testing equipment that state and local governments procure for research institutions, public health departments, and education programs. Recent solicitations show demand for whole-body plethysmography systems and related diagnostic instrumentation, often bundled within broader equipment acquisitions for academic medical research or career technical education pathways. Issuing bodies span higher education institutions, independent school districts, and cooperative purchasing vehicles that aggregate demand across multiple jurisdictions. Texas State University and Klein Independent School District (Klein ISD) in Harris County, Texas represent the kinds of end-users soliciting under this code in recent months.

Activity concentrates in Texas, where Texas State University issued an Invitation for Bid (IFB 754-TXST-2026-IFB-470-RC) on April 3, 2026, for a whole body plethysmography system with cryogen-free superconducting measurement capability designed to support pulmonary and respiratory function testing; the bid deadline was April 3, 2026. Klein ISD's Request for Proposals (RFP 26-101) for Career Technical Education and Advanced Academics, due June 5, 2026, encompasses health sciences instructional equipment and materials where diagnostic devices may be specified as part of program delivery. Beyond Texas, Sourcewell—a Minnesota-based cooperative purchasing entity—posted RFP 061626 for law enforcement equipment on May 12, 2026, with a June 16, 2026 deadline, which may include diagnostic or medical-screening apparatus for participating law enforcement agencies across Washington state and other jurisdictions; however, the solicitation does not explicitly name diagnostic respiratory equipment within its scope. Vendors should access full technical specifications and evaluation criteria through each issuing body's procurement portal, as budget ranges and specific equipment requirements are not disclosed in available summary documentation.
