Why Yokogawa Test & Measurement is the world’s most trusted measurement partner.


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 over 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.


n 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.

We are The Precision Makers

Precision is all around us, in everything we see, and in everything we touch. It means the difference between success and failure, safe and unsafe, sustainable and unsustainable.
