The Yokogawa Group’s corporate philosophy has at its core, the goal, - ‘to contribute to society through broad-ranging activities in the areas of measurement, control and information’. Yokogawa Electric Corporation was established in 1915 by Dr. Tamisuke Yokogawa to manufacture the first electric meters in Japan. Measurement was the foundation for the original business and remains a strong and important driver for our business. Ever since those early days, Yokogawa has been providing products and solutions that continue to satisfy the ever changing demands of modern technology. Keeping ahead of technology measurement needs has involved dedicated focus, strong attention to detail, specialist and highly experienced engineers and above all the belief that no product or solution leaves the Yokogawa manufacturing line without being of the highest quality.
Measurement is important to us all. It is the ability to quantitively express certain physical values that provide indications to the quality, performance and function of the item being measured. To ensure the quality and performance, the measured value must be reliable. It is not sufficient for a measuring instrument to measure only on given days. It must obtain the same value over intervals of time, regardless of the environmental conditions it must endure. That is why the spirit of ‘quality first’ is an integral element in meeting our corporate philosophy goal.
With almost 100 years of experience, we have built our reputation on understanding the needs of scientists and engineers that require both the accuracy of a measurement system and its precision where stability and reproducibility ensure that repeated measurements under unchanged conditions show the same results.
A measurement system can be accurate but not precise, precise but not accurate, neither, or both. A measurement system is considered valid if it is both accurate and precise.
In Yokogawa T&M, we are in the business of accuracy and precision. ‘Precision’ is what we make and ‘Precision Making’ is what we do. We are the ‘Precision Makers’.
That is why scientists and engineers see Yokogawa T&M as the world’s most trusted measurement partner.

Yokogawa Calibration Laboratory Manager
Test & Measurement, Yokogawa Europe
Amersfoort, The Netherlands
My name is Erik Kroon. I joined Yokogawa Europe 1990 to set up the calibration laboratory in Amersfoort and develop test systems for the YPA factory.
From 2000 to 2008 I worked for national standards laboratory in the Netherlands (VSL Dutch Metrology Institute) where I was responsible of the Time and Frequency, High Voltage standards and was involved in power calibrations. During my work at VSL I joined the ‘Consultative Committee for Time and Frequency (CCTF)’ at the ‘Bureau International de Poids et Mesures’(BIPM) after which I rejoined Yokogawa. I’m also a former auditor for ISO 17025 for the Dutch Council of Accreditation (RvA) and a current member of technical committee for the RvA.
Over the years I have dedicated my work for ensuring accuracy in high-precision power measurements as a Yokogawa calibration laboratory manager.
When I rejoined Yokogawa as the calibration manager, my personal goal was to establish the best power calibration laboratory in Europe as a non- National Standards Laboratory.
As more and more innovation focuses on energy efficiency and the use of renewable energy resources, engineers are increasingly demanding accuracy and precision from their power measurements. At the same time, new standards such as IEC 62301 Ed2.0 and EN 50564:2011, covering standby power consumption, and the SPEC guidelines, covering power consumption in data centres, demand more precise and accurate testing to ensure compliance. To meet these challenges, R&D teams are increasingly confronted with the need for new levels of precision in power measurement that can only be achieved if the measuring instruments are properly calibrated with reference to national and international standards. Therefore, I am proud to announce that Yokogawa’s European Calibration Laboratory has become the world’s first non-governmental facility to receive full ISO 17025 Accreditation for power measurements at up to 100 kHz.
This is in addition to its established capability for providing high accuracy calibration at 50 Hz, especially at very low power factors (down to 0.0001) and at high currents. The recognition offered by this accreditation is objective proof that the knowledge of our personnel and the quality of our instruments are world-leading.
For customers working with tight tolerances, ISO 17025 accredited calibration of the measurement is vital to major critical measuring projects and provides the high level of quality assurance that our customers need. Without high-quality in-house calibration facilities, instrument manufacturers cannot provide the sort of evidence that is available to Yokogawa to show that their instruments perform within their specifications. I can honestly say, for example, that our WT3000E power analyzer is the most accurate power analyzer in the world, with proof provided by its accreditation certificate.
Outside of precision making at work, I do admit I’m a self-confessed geek who loves technology. I am an active radio amateur developing and building relay stations. Another passion of mine is a cockpit building. Not so many people can say they have a model built cockpit at home. Rest of my free time I’m enjoying spending with my wife, two children, dog and cat.

General Manager, Strategic Development Department
Yokogawa Meters & Instruments Corporation
My name is Ken Haga and I graduated from the Waseda University Faculty of Science and Engineering in 1988 before joining Yokogawa Electric Corporation.
Over the years I have developed a varied and deep knowledge in Test & Measurement working with Yokogawa's highly experienced research and development organization as well as international experience, gained whilst working in the United Kingdom. My successes include the development of the high precision 12 bit resolution digital oscilloscope DL3100, one of Yokogawa's first series of digital oscilloscopes and the high speed 10 bit digital DL4100/4200 oscilloscope series. I was also deeply involved in Yokogawa's designing of analog devices such as AD converters, probes, and input circuit systems. I am very proud that these products made a significant impact on the oscilloscope market and have given customers a credible alternative to other oscilloscope manufacturers. This has been mainly due to our company's philosophy to be innovative in our approach and my desire to cover every small detail. With unique selling points and well defined benefits to the customers, these products became well-known in the mechatronics and medical electronic equipment markets. The key requirement being precise measurements of low noise waveforms. This requirement for precision ensured customers could rely on high quality results and in turn secure their own product developments.
In order for me to qualify as a ‘Precision Maker’, it was very important for me to work closer with the customer and understand their working environments and needs. From 1999 to 2003, I worked in technical sales support and in sales for Japanese-affiliated companies uncovering new markets and business opportunities for communications/broadcasting related measurement equipment. I enhanced that experience through working as a Business Development/Marketing Manager in Yokogawa Martron Ltd., based in the UK. I returned to the Yokogawa Electric Corporation Engineering Department in 2004 and became responsible for developing the DL9000 and DLM2000 series oscilloscopes as well as developing differential and wide frequency range active probes for these oscilloscopes - Yokogawa's first originally developed probes.
I am recognized by my colleagues as an expert in high frequency wave circuit technology for measurement and I am currently responsible for the Common Technology Department. This involves the next generation embedded CPU systems, innovative software platforms and mechanical design for high quality and cutting-edge technology development for sensors and probes. I also hold several patents.
As well as being a ‘Precision Maker’, at work, I try to be one at home as well. Playing tennis with my daughters and coaching them to make accurate tennis shots and time in the ‘Kitchen’ garden growing and nurturing tomatoes, something that needs precise control, especially on hot summer days.
