UNSPSC 41115515: Hydrophone

A sound electric converter that reacts to the underwater sound energy to convert the energy into the intrinsically consistent (same) electric energy and stimulate the electric form factor, This machine is specially manufactured to use in water.

UNSPSC 41115515 Hydrophone is a Commodity code for underwater acoustic sensors that state and local governments procure for marine research, environmental monitoring, and coastal infrastructure applications. The code captures devices used to detect, record, and analyze underwater sound signals across a range of frequencies and deployment contexts. Purchasing bodies in this category include state environmental and natural resources agencies, coastal management departments, university research institutions operating under state procurement frameworks, and special-purpose water districts managing estuaries, harbors, and marine protected areas. The work typically involves procurement of single units or small quantities of specialized hydrophones, calibration services, and associated acoustic recording equipment.

The source provides no recent state or local contract opportunities under this code. Without posted RFP, RFQ, IFB, or ITB notices in the available data, geographic concentration and representative solicitation activity cannot be determined. Practitioners should monitor procurement portals in coastal states and those with significant university research infrastructure, but the apparent absence of recent activity under this specific Commodity code suggests either infrequent procurement cycles, use of related but differently coded acoustic equipment categories, or direct procurement through specialized research vendors outside standard state and local competitive bidding channels.
