What Hioki Do
Hioki has pursued unique technologies over its history so that it can provide new value to customers through high-quality products. For about 40 years after our founding in 1935, our business centered on volume production of meters and testers. Starting in 1974, we modernized our management and pursued an aggressive R&D program that yielded today’s four product groups. The result has been a distinctive portfolio that includes no-metal-contact voltage measurement technology, high-sensitivity current measurement technology, and other innovative technologies.
