UNSPSC 41115610: Conductivity cells

UNSPSC 41115610 Conductivity cells (Commodity) encompasses laboratory and field instrumentation used to measure thermal and electrical conductivity of materials and geological formations. State and local buyers under this code include municipal engineering departments, public universities, and research institutions conducting thermal property analysis for building systems, material science, and site characterization. The City of Madison Engineering Department, University of Wisconsin-Madison, and University of Southern Mississippi represent the issuing bodies in recent activity, ranging from infrastructure feasibility studies and facility retrofit projects to laboratory equipment procurement and sensor upgrades. Work being solicited spans field thermal conductivity testing of geothermal bore formations, laboratory thermal analysis systems for composite and coating evaluation, and specialized sensor software for existing thermal conductivity instruments.

Recent opportunities show geographic concentration in the upper Midwest. The City of Madison posted an IFB (Solicitation 1505302026TJ, due August 24, 2026) for thermal conductivity testing and analysis services as part of an 800-foot geothermal test bore at Monona Terrace, supporting the city's greenhouse gas emissions reduction goal, with all work to be completed by December 4, 2026 under a fixed-fee contract. The University of Wisconsin-Madison issued an RFB (2027-UWMSN-01387-RFB, due July 17, 2026) for a Simultaneous Thermal and Gas Analysis System acquisition. The University of Southern Mississippi procured software for a TPS Anisotropy Upgrade sensor under sole-source justification (RFx 3150006844, objections due June 8, 2026) at $14,400, citing exclusive compliance with ASTM D7984 standards and the required thermal conductivity range of 0.01 to 500 W/mK with operational temperature capability from 50°C to 200°C.
