What’s the difference between ZOYI&ZOTEK ZT-702S and ZT-703S?
The most comprehensive answer here. Many people are puzzled why ZOYI released the ZT-702s and ZT-703s within a year of each other. Why not release them together to offer consumers more choices? The answer is, that ZOYI has been in the multimeter industry for 40 years, and it was not until 2019 that we initiated our handheld oscilloscope project. After three to four years of continuous research and development, we finally perfected the functionality of the single-channel handheld oscilloscope ZT-702s and commenced mass production at the beginning of 2023. Throughout 2023, we were also testing the dual-channel handheld oscilloscope ZT-703s.
