The main products are special measuring instruments installed onto the transformers or the gas circuit breakers in power plants and substations. They are adopted by domestic and overseas nuclear, thermal and hydraulic power plants and substations. Since almost all processes, including material procurement, machining, assembly and adjustment, inspection, and shipping, are performed by ourselves, it is possible to deal with the various needs of the customers.

Specialized Products, Technologies and Services

Labor-saving solution for pressure monitoring

The pressure gauge with sensor port (patent application pending, utility model registered) is a revolutionary new product that enables easy remote monitoring by replacing an existing pressure gauge.
The pressure monitoring is ensured by transmitting and receiving data from the installed sensor in real time while utilizing the visibility of analog gauges.
Wireless network system using LPWA, which has a long communication distance, makes it possible to realize IoT at low cost even in large-scale factories and plants.

Products that support the development of society and industry

Because our special meters have a long service life and are highly reliable, those have been adopted in many important facilities such as power plants and substations in Japan and overseas as protective devices to prevent accidents.
Our instruments for railway vehicles are mainly used overseas to support safe operations.

Development and testing

Instruments for power stations, which are required to have long life and high durability, must pass strict tests.
We have introduced a variety of testing equipment, and can conduct almost all type tests in-house.
Our customers in the space and aviation sectors use our vibration testing services.
