CID Bio-Science, Inc., has been designing instruments for agricultural and environmental plant research for over 25 years. Our company was established in 1989 with the introduction of our state-of-the-art handheld photosynthesis system. Since then we have expanded to develop 13 instruments to measure plant function, continuously employing new innovations and technologies. Headquartered in the Pacific Northwest of the United States, CID instruments are represented by distributors in 44 countries.

In 2012, we renovated a historically-landmarked building to be our headquarters in Camas, WA. Our new home not only represents our commitment to our community, but symbolizes our company's creative philosophy: to pursue the innovative path and commit to the best possible vision of what we can create in everything we do.

From the beginning, CID has maintained a commitment to superior product innovation, superior customer service, and superior value. Contact your local distributor to see why researchers have trusted CID Bio-Science to provide the world's finest portable instruments for plant science research.
