In 1917, Yokogawa were the first to produce and sell electric meters in Japan.
In the mid 1930’s, they expanded their product range and started researching and manufacturing aircraft instruments and flow, temperature, and pressure controllers. Over the following years they continued to develop other measurement instruments, and their success with exports around the world saw them establish plants in Singapore, Europe, and China.
Today Yokogawa are considered leading providers of test and measurement solutions. Their multimeters, clamp meters, leakage testers, and other instruments utilise superior engineering services and technology, and Yokogawa consistently deliver field-proven operational efficiency, safety, quality, and reliability.
