EKO Instruments
Who we are

Established in Tokyo in 1927, EKO began with the distribution of instruments for the Japanese meteorological and environmental market. In the 50’s, the company developed and produced its first solar radiation sensors to meet with the ever evolving needs of the scientific community. Since the beginning, renewable energy and environmental topics have been our focus and have directed our main strategy.

We now offer a unique range of high precision broadband and spectral radiometers, as well as various I-V measurement devices for the evaluation of photovoltaic components, systems, and energy plants.

All products are manufactured with a high emphasis on quality, innovation and creativity. EKO is also a center of competence offering know-how and customized services for the photovoltaic industry and instrumental meteorology on an outstanding scientific level.

We are the only solar sensor manufacturer having its own ISO 17025 accredited testing laboratory for the calibration

of pyranometers and pyrheliometers. ISO 17025 gives our clients another proof of the precision and reliability of our measuring instruments and calibration methods.

International customers will benefit from smart instrument synergies and innovative services, which persistently improve and optimize the efficiency and quality of their photovoltaic systems and meteorological research. Through its worldwide distribution network and regional offices, EKO developed into a leading global player, which is known for its instrument durability, reliability and precision.

Our values

It is the aim of EKO to help its customers to get ahead by developing turn-key research solutions and services for the photovoltaic and meteorological markets. With our high level of know-how and latest technologies used in the photovoltaic measurement equipment
and solar radiation sensors, we aim to extend your solar research capabilities in functionality, accuracy and quality. EKO unique Solar Monitoring Station (SMS) is considered a reference in PV to collect high-quality solar irradiance data on-site.

The principle of PV performance monitoring is to relate the total energy input, which is the incidence solar irradiance, to the energy output in units of electrical power produced by the photovoltaic cells, modules, or installations. EKO’s distinct range of I-V tracers and high precision solar sensors can be flexibly configured as one PV evaluation system according to the latest international standards.

EKO Instruments is split into 2 business units:

Environmental Instruments and Material Characterization & Analysis Divisions. The Environmental Instruments Division focuses on evaluation of photovoltaic performance, radiation and spectral measurements.

The Material Characterization & Analysis Division develop sensors for conductivity testing, food quality and control, and pharmaceutical and cosmetic analysis.
