At Decagon Devices we design, manufacture, and market scientific instruments. Focusing on measuring water, light, and heat in the soil-plant-atmosphere continuum. Our instruments are used throughout the world in universities, research and testing laboratories, government agencies, vineyards, farms, and industrial applications.

Decagon was founded in 1983 by Dr. Gaylon Campbell, who is an old-school physicist. When he wanted to measure something, he built an instrument to measure it. Other people wanted his creations, and eventually he couldn't keep up with the demand, and so Decagon was formed. More than 25 years later, Decagon is a thriving company where research scientists still work to build what they and their colleagues need to do good research.

Our goal at Decagon is to get the data you need into your hands in the most efficient and accurate way possible.

Decagon is located in Pullman, Washington, home of Washington State University.
