Hioki Logo

Mizo Hioki started manufacturing the Hioki electrical measuring instruments product range in Tokyo in 1935, operating under a company in his own name.

Seeing early success and envisioning more growth for the future, he established HIOKI Electrical Instrument Works in 1938.  Mizo’s brothers, Mineji and Shiro, joined him in the business in 1942.

In 1946 Hioki launched their first tester, the Model H Circuit Tester.

In 1952 Hioki became the designated manufacturer of military spec multi-testers for use by the US Air Force (in the Far East) in their aircraft maintenance.  The favourable response they received from this arrangement with the US Air Force, led to Hioki exporting testers to North America just a couple of years later.

After developing and launching a number of new products locally, Hioki, in 1977, launched their product range in the US market.

In 1984, Hioki began exporting their products to the Chinese market.

Hioki regularly released new instruments to the market, and were consistently recognised as award recipients for their innovation, quality, safe work practices, being certification compliant, and their commitment to the environment, specifically afforestation.

In 1998 the local subsidiary Hioki USA Corporation was established in the United States.

The product launches, awards, and recognitions continued, and the growth Hioki has experienced led them to open divisions and offices in Taiwan, Shanghai, India, Singapore, South Korea, Dubai, Indonesia, and Europe.  Head Office for Hioki is located in Hioki Forest Hills, Ueda, Japan.

HT Instruments logo

HT Instruments are products of company HT Italia, which was born in Italy in 1983.  Their mission has always been clear… to become the leader in the electrical technical sector.

In 1992, after nearly a decade of experience and gathering ideas, HT started designing and building their own instruments.  They created their first model, the Master HT2031. At that time, no competitor could offer a product performing safety testing on installations and simultaneously printing a professional report via a built-in printer.  The success of this new equipment gave HT the fuel it needed to start a research team of engineers responsible for designing and developing further instruments.  

The implementation of this team enabled HT to strengthen their sales network all over the world, and in 1994 they opened a subsidiary in Spain, with the aim of bringing their technology to emerging markets.

1996 saw the development of HT’s FullTest HT2036, the only instrument on the market capable of testing safety conditions on equipment and electrical panels.

Further development led to HT launching the Genius 5080 in 1999, another innovation, being the first instrument to combine testing of electrical safety with power analysis. A real step forward in the world of instruments.  This type of product has been featuring HT among all its competitors.

In 2000, HT launched the 2000 series, consisting of 6 models, all designed to meet the requirements of every electrical installer and designer.

Only a year later, HT launched the series GSC, the first instruments on the market combining safety testing on electrical installations with single- and three-phase analysis of power quality.  GSC represented a revolution in technology and communication. 

Just a few months after its launch, HT could count on thousands of sales worldwide. GSC is still today a real icon in the equipment field.

The company continued to evolve and develop new and innovative products, including the VEGA76 in 2004, the 400 series in 2007, and the PQA series (extremely advanced and unmatched on the market), also in 2007.  Each of their new product releases showed HT’s intention to invest in technology and remain a pioneer in its market.

In 2007 HT INSTRUMENTS GmbH was founded, a second branch located in Germany.

In the years since, HT’s R&D team have continued to develop and release new and cutting edge products, including multimeters and clamp meters, to the market, keeping them as one of the top names in the field of electrical test and measuring equipment.  They are known for their attention to detail, their functionality, practicality, and precision.  

Made in Italy, HT Instruments ensure new products undergo meticulous and rigourous inhouse testing, before being released to the market.  They are used to the extreme and pushed to the max, ensuring that they are incredibly reliable pieces of equipment. They are also attractive, lightweight, easy to use, safe, accurate and versatile.

The range of HT Instruments is constantly growing and improving, and their technical innovation, alongwith their lasting value, makes HT Instruments well respected names in the multimeter and clamp meter industry.
