Decagon was founded in 1983 by Dr. Gaylon Campbell, a renowned soil scientist at Washington State University. Dr. Campbell hoped that the company would both provide employment for his teenage children and provide his fellow researchers with useful scientific instruments. Almost 25 years later, Decagon has grown into a prosperous business that retains an emphasis on research and engineering. As the designer, manufacturer, and marketer of its instruments, Decagon prides itself on excellent customer service and support.
