Since our founding in 1935, Hioki has been involved in the development, manufacture, and sale of electrical measuring instruments, a category of indispensable tools that plays a fundamental role in modern industry. During the early part of our history, mass-produced meters and testers comprised the bulk of our business, but more recently we have sought to create one-and-only products by utilizing a range of sensor technologies spawned through our development of HIOKI-brand products.
