Established in 1993 with more than 25 years of distribution and manufacturing experience in measuring devices, YUDEN-TECH is now the largest instrument sensor manufacturer in Taiwan.

In the early stage, we mainly acted as an import agent and introduced international famous brands. In the field of precision instrument measurement, we accompanied the Taiwan manufacturing industry to improve the efficiency of manufacturing process and the safety of working environment. With many years of sales experience and expertise, we passed the ISO 9001:2008 quality certification in 2009, and then invested in the R&D and manufacturing of our own brand eYc.
