Humidity measurement equipment

Our products are used in the applications where precise humidity control is required, such as air conditioning control in homes, buildings and factories, and industrial applications, i.e. semiconductor production lines and clean rooms, and also museums and aerospace development. We are also developing and manufacturing humidity generators ensuring the criteria, and providing products and services related to accuracy maintenance with JCSS (humidity) calibration.
We are also conducting research and development for high-precision humidity measurement based on traceability systems.

Capacitors

Since we developed the world's first Polypropylene (PP) film capacitors in 1965, we have advanced into the fields of television, lighting, audio, and power electronics to meet the needs for miniaturization and high-performance required in those fields.
We provide PP film capacitors with high frequency, large capacitance value, high heat resistance that can be used in the inverters taken into various types of equipment.
With two locations in Nagano and Malaysia, we are promoting research and development works and running the production in the optimal location for maximum efficiency to improve our competitiveness in the field of film capacitors which are important electronic components.

Environment measuring equipment

In 1994, we developed and mass produced the world's first optical dust sensors, which are now installed in many air purifiers. In addition, we commercialized pollen sensors that can automatically measure pollen using our unique patented technology for the first time in the world.
Thereafter we have achieved high performance optical detection, and our products are used in many scenes of particle measurements, i.e. particulates detection for clean rooms, large particles detection for painting processes and PM2.5 detection.
In addition, we have produced odor monitors for odor measurements besides particle detection measurement. For those reliable products, we have earned customers' high trust and reputed as experts in environmental measurement.

Testing machinery and measuring instrument

Along with the widespread use of mobile devices, expansion of home delivery opportunities through internet shopping, and diversifying distribution forms, there are increasing risks that products and packages are dropped or shocked.
We develop, manufacture, and sell test machines and measuring instruments which visualize the conditions of shock and drop during the transportation.
Also, our test machines and measuring instruments are contributing to the safe and comfortable railway maintenance.
