'EKO Shokai' was founded by Hiroshi Tozawa (pictured) & Eiji Shiina and was the first meteorological instrument manufacturer in Japan.
EKO started manufacturing the MS-12, the EKO started manufacturing the MS-12, the first Japanese-made pyranometer.
EKO launches the first Japanese-designed and built pyranometer.
A group of EKO sensors were installed for the first time at the Mizuho Station in Antarctica after being selected by the Japanese Ministry of Education for a long-term research project.
EKO produced its first I-V Tracers, research equipment specifically designed for solar power generation systems.
EKO launched the MS-210W, the world's first UV-B radiometer.
EKO obtained its first international ISO standard accreditation for quality management.
EKO establishes its first permanent office outside of Japan, opening EKO Instruments USA Inc.
EKO Instruments Europe B.V. opens in the Netherlands, bringing EKO closer to customers across the continent with the first EKO technical centre outside of Japan.
EKO celebrated its 85th anniversary and moved into its first custom-designed HQ in Japan.
EKO became the first ISO/IEC 17025 certified solar sensor manufacturer in the world, helping to validate and maintain the highest standards in calibration and testing.
Between 2013 and 2015, EKO opened two solar parks near Tokyo, becoming the first, and still only, solar sensor manufacturer in the world to own and operate its own PV plants.
EKO re-defined expectations for accuracy and performance with the launch of the MS-80, the first in a new generation of pyranometers, featuring a state-of-the-art thermopile sensor & quartz diffusor technology.
EKO made its first public sustainability pledge, a commitment to phase out all possible single-use, and non-recyclable plastics from product packaging by the end of 2022.
EKO announced EKO EMPOWER, the first global sponsorship and education programme by a solar sensor manufacturer, initially supporting six university-based solar car racing teams from around the world.
EKO launches its first 100% Renewable Energy powered website and a new 'Vision & Mission' in preparation for our 100th anniversary in 2027.
EKO Instruments launched the MS-10S UVA and MS-11S UVB sensors, enhancing precision in UV radiation measurement. EKO also completed its first complete digital solar monitoring solution by launching the Digital MS-57S Pyrheliometer, setting a new standard in solar irradiance monitoring.
EKO Instruments introduced the first Class A sensor, MS-80SH Plus+ Solar Monitoring Station, specially designed for bifacial applications. This innovation marked a significant advancement in the monitoring of bifacial PV systems, improving efficiency and performance analysis.
In 2024, EKO launched its first small heat flux sensor, the HF-01S. Compact and highly sensitive, it delivers accurate heat flux measurements for research, engineering, and manufacturing applications.
