Everything is becoming electrical
In a decarbonizing society, electricity generated by carbon-free methods will become the primary source of power. Hioki's electrical measurement technologies will contribute to solving challenges across various fields in a future increasingly permeated by electrification.
A manufacturer, not a catalogue
Hioki products supporting industry and daily life. Hioki's measurement technologies contribute to the development of next-generation technologies such as mobility, batteries, and new energy solutions, while also supporting high-quality and cost-effective manufacturing. Our products, which are also widely used in maintenance settings for plants, infrastructure, buildings, and factories, play a crucial role in ensuring safety and reliability.
What has to be true inside the company
Four criteria of innovation, and the reason a measurement can be trusted outside it.
Increasing customer value
Production system
A production system built so that a measurement need turns into a delivered, calibrated instrument without the customer absorbing the delay.
Delivering peace of mind to customers
After-sales service
An instrument is only as good as the number it still reports in year five. After-sales service exists to keep that number trustworthy.
Pursuing productivity and precision
Manufacturing capabilities
Precision is a manufacturing capability before it is a specification. It is held in the process, not promised in the catalog.
Creating new customer value
Collaborative development of new products
When a field has no instrument for the quantity it needs to see, the instrument gets developed with the customer who needs it.
Tell us what you need to measure.
Not which model you want. The quantity, where it sits, and how good the number has to be. A measurement engineer reads it and replies with ranges, methods and the conditions under which the result is trustworthy.
