UNSPSC 60104918: Photoelectric apparatus

A device which can demonstrate the photo electric effect and the Planck constant by using the photo electric tube. It can identify the wave length of the light, and it consists of a photo electric tube, the amperemeter, the light source, and the current amplifier.

UNSPSC 60104918 Photoelectric apparatus, a Commodity code, does not align with the recent state and local contract opportunities tagged under it. The code nominally covers photoelectric sensors, light-detection devices, and related optical instrumentation; however, the five solicitations posted in the block describe educational materials, science supplies, instructional equipment, and STEM kits for K–12 school districts. The mismatch suggests either a tagging error in the source data or a significant scope divergence between the code's technical definition and how it is being applied in practice by school districts.

The opportunities do reflect what school districts are actually buying: reading and video materials, instructional supplies across multiple subject areas (English Language Arts, Mathematics, Science, Social Studies, Health/Physical Education, Arts & Crafts), special education assistive technology, bilingual and ESL materials, science specimens and chemicals, and STEM and College & Career Readiness kits. Issuing bodies include independent school districts in Texas (Harlingen Consolidated ISD, Katy ISD), Florida (Seminole County School Board), Georgia (Cobb County School District), and Arizona (Cartwright Elementary School District No. 83 on behalf of the SAVE consortium). Recent solicitations span RFPs and IFBs with response dates ranging from May through October 2026. If this code genuinely tracks photoelectric apparatus procurement by state and local agencies, the recent-opportunities block shows little relevant activity. Vendors should verify the correct UNSPSC classification with issuing bodies before pursuing opportunities listed under this code.
