大田計器製作所 Company Profile

Manufacturing, sales, repair, and calibration of meteorological observation instruments. Since our establishment, we have focused on in-house production of meteorological observation equipment and after-sales service.

Ohta Instrument Manufacturing Co., Ltd. believes that people's lives are influenced by the environment, economy, culture, and even health, all of which are affected by climate. Weather observations such as wind speed are essential activities for reading the "subtle signs emitted by the Earth," represented by phenomena like global warming. They play a crucial role in understanding and predicting the fine changes in nature, allowing us to respond and shape both the present and the future. Ohta Instrument Manufacturing Co., Ltd. views weather observation instruments as an "interface connecting nature and humanity" and has developed and provided high-precision products using cutting-edge technology for many years. Based on a traceability system constructed according to national standards, including the Measurement Law and the Japan Meteorological Agency's testing standards, we are expanding various inspection facilities and equipment while conducting rigorous product checks. Weather observation instruments are often used in harsh environments, and the reliability of our products depends on how accurately they can measure data under such conditions.
