About Us

Founder: Mr Li Hong, one of the greatest digital multimeter pioneers in China.

In 1984, Mr Li introduced the first digital multimeter production line of DT830 to China. 

In 1996, he designed a few digital multimeter chips in Taiwan. E.g. FS9721, FS9952, FS9922 and so on. 

In 2011, he produced MCU chips for the digital multimeter. Meaning all manufacturers can use more cost-effective chips to reduce total production costs.

CEO: Mr.Li Xin, son of Mr.Li Hong. Founded the company ZOYI with his father. In 5 years, ZOYI became a well-known brand within the industry. He also designed more revolutionary multimeters, like ZTX, ZTY, ZTM1, ZTQB9, ZT922 and so on.  

We are striving for the title of the top multimeter manufacturer in the world.
