## Description

The manufacturer of ZOYI&ZOTEK has been committed to the production of digital multimeters since 1984 and adhered to the principle of independent research and development all the way to today.

We have been adhering to the idea of ​​"seeking common ground while reserving differences and common development", insisting on "quality-oriented, creating a win-win situation" as the foundation to contribute our own strength to the majority of measurement and testing users, and "making measurement more effective" is our goal which is also the direction we have been working hard for.-------------------------------------------ZT-E4 R&D background: Why can't the socket tester be used to have a big screen? Why can't the detection results be displayed intuitively to the user? Aren't tools for the convenience of the user? How to display test results? Make the measurement more effective - the test results are easy for users to view at a glance. ZT-E4 went through six months of research and development and testing from January 2020 to June 2020 and officially went offline to meet with users.
