Established in Tokyo in 1927, EKO began distributing sensors for the Japanese meteorological and environmental market. In the 50s, we launched the first Japanese-designed and built pyranometer, producing a range of solar radiation sensors to meet the ever-evolving needs of the scientific community.

Since the beginning, renewable energy and the environment have been at the heart of what we do, guiding our mission to produce the most accurate solar radiation sensors and scientific instruments in the world.
