UNSPSC 41114430: Transmissometer

A transmissometer or transmissiometer is an instrument for measuring the extinction coefficient of the atmosphere and sea water, and for the determination of visual range. It operates by sending a narrow, collimated beam of energy (usually a laser) through the propagation medium.

UNSPSC 41114430 Transmissometer is a Commodity code that classifies specialized aviation and meteorological measurement equipment used at airports and weather facilities. State and local governments procure transmissometers—instruments that measure atmospheric visibility and light transmission—primarily for airport operations, runway safety systems, and weather monitoring infrastructure. The code shows minimal relevant recent activity; the recent opportunities block contains no active solicitations specifically targeting transmissometer equipment or directly related visibility-measurement instruments. Instead, the block presents a broad mix of airport and transportation equipment procurements (aircraft tugs, boarding ramps, boarding stairs, ramp sweepers, and ground support systems), runway lighting and edge-lighting components, aircraft maintenance systems, and bus wash equipment—none of which map to transmissometer functionality or the visibility-measurement scope the code nominally covers.

The issuing bodies in the recent dataset span state transportation departments, county purchasing offices, municipal aviation departments, and airport authorities across Florida, Texas, Georgia, New Mexico, Kentucky, and New Jersey, with no standout pattern of repeat buyers targeting this specific code. Geographic concentration is evident in Florida and Texas airport operations, but that activity reflects broader airport infrastructure and ground-support procurement rather than visibility-measurement systems. Absent a current transmissometer opportunity in the block, the code presents limited pursuit signal for vendors in this space at present. If visibility-measurement or transmissometer needs surface in the near term, they would most likely originate from state or municipal airport authorities, FAA-compliance-driven airport upgrades, or weather service facilities—but the recent posting environment does not reflect active demand.
