Manufacturer of electrical measuring instruments
Hioki Electrical Measuring Instruments

Measure it properly,
the first time.

Hioki designs and builds the instruments that industry, infrastructure and next-generation energy depend on — from a handheld multimeter to an automatic board test system. Tell us what you need to measure and an engineer answers with ranges, not adjectives.

18 product groups across four categories, used across 4 fields from power distribution to lithium-ion cells. Enquiries are read and answered by measurement engineers.

All 18 groups, by what they measure

The measured quantity is the only column that matters when you are looking for an instrument, so it is the one every card leads with.

Tell us what you need to measure.

Not which model you want — what the quantity is, 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.

The four criteria of innovation

What has to be true inside the company for a measurement to be trustworthy 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.
