UNSPSC 41115311: Photometer

An instrument that measures the strength of electromagnetic radiation in the range from ultraviolet to infrared and including the visible spectrum. Most photometers convert light into an electric current using a photoresistor, photodiode, or photomultiplier.

UNSPSC 41115311 Photometer is a Commodity code that historically names laboratory and analytical instruments for light measurement. Recent state and local solicitation activity under this code does not reflect that nominal scope. The Georgia World Congress Center Authority's June 2026 RFQ for Owner's Representative Services on the GESPC II Project—a guaranteed energy savings performance contract covering building automation systems, HVAC infrastructure, cooling towers, kitchen ventilation, and generator peak shaving at an active convention center—bears no functional relationship to photometry or light-measurement equipment. The code assignment appears to be a classification mismatch rather than a genuine procurement need for photometric instruments. No other recent state and local opportunities under UNSPSC 41115311 are present in the source.

Because the single recent opportunity tagged to this code addresses project management services rather than photometer equipment or supplies, the code shows little relevant activity for vendors serving the photometry market. Firms evaluating pursuit under this UNSPSC should verify opportunity classification before committing business development resources—the Georgia solicitation, while active and governed by standard RFQ process (six copies of qualifications due June 15, 2026, with a mandatory pre-bid June 3), does not align with photometer product or service delivery.
