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 (Commodity) does not show meaningful recent state and local procurement activity aligned with its nominal scope. The code's definition—optical instruments that measure light transmission through air or atmospheric conditions—does not match the recent opportunities tagged under this classification.

The source records zero recent solicitations for transmissometers, atmospheric measurement devices, or optical transmission testing equipment from state and local buyers. Instead, the opportunities posted under this code span airport operations (airfield photometric testing, baggage handling system operation, passenger boarding bridge procurement), aircraft maintenance (Cessna engine procurement, Lycoming parts), emergency bridge replacement, traffic signal supply, and other infrastructure work wholly unrelated to light transmission measurement. The mismatch suggests either a tagging error in the source data or that this particular code sits dormant in state and local procurement workflows. No issuing bodies, contract values, response dates, or geographic clustering emerge from the records that would support a viable pursuit strategy. Prospective vendors should verify actual recent opportunities through direct RFP channels or cooperative purchasing agreements rather than rely on this code classification as a procurement signal.
