LI-600PF + LI-600N Porometer/Fluorometer Package

Oregon State University is seeking to purchase a combined LI-600PF + LI-600N Porometer/Fluorometer Package from LI‑COR Inc. as a sole‑source acquisition to support tree‑physiology research. The instruments must simultaneously measure stomatal conductance and chlorophyll fluorescence in both broad‑leaf and narrow‑leaf specimens, integrate with the existing LI‑COR Connect software, and be field‑portable for use in forest environments. No other vendor offers a product that meets all four specified requirements, prompting the sole‑source justification. The solicitation closes on April 30, 2026 at 1:00 pm PST, and questions or appeals must be directed to the university’s procurement office.
