What We Do
Bringing the value of measurement to every industry.
Hioki is an industry-leading manufacturer of finest electrical test and measuring instruments since 1935.
Electrical measuring instruments are versatile tools used across a wide range of fields, including product R&D, production, and maintenance inspections of electrical work.
Creating new value through proprietary technologies
We’ve pioneered world-first technologies such as non-contact voltage measurement for metals as well as proprietary high-precision current sensing, high-frequency measurement, laser-based measurement, and micron-level probing techniques. These technologies have helped us build products that resolve customers’ issues efficiently from a customer-centric perspective.
A diverse range of product categories: From R&D to maintenance service
Hioki provides four main categories of products: automatic testing systems, recording equipment, electronic measuring instruments, and field measuring devices. These tools are used across a wide range of industries, from research and development to the maintenance of facilities and equipment.
