Zoyi ZT703S 3in1 Oscilloscope Multimeter Dual Channel 50MHz

Meet the Zoyi ZT703S, a compact 3-in-1 tool that combines a digital oscilloscope, a digital multimeter, and a built-in signal generator in one handheld device. With a dual-channel oscilloscope offering 50 MHz bandwidth and up to 280 MS/s sampling, you can capture detailed waveforms and analyze circuits with confidence.

Enjoy a bright 3.5-inch color display that makes readings clear, and experience true RMS measurements for accurate AC and DC values. The device supports AC/DC voltage and current, along with resistance and capacitance tests, delivering essential electronics testing in a single, portable instrument. Built with durable ABS+silicone housing and immersion-gold PCB, it’s designed for reliability in both workshop benches and fieldwork. The built-in waveform generator and automatic waveform measurement/recognition further streamline testing, so you get results quickly without guesswork.

Safety and reliability are built in: full overload protections, an intelligent anti-burn chip, double ceramic fuses, and a high-voltage protection module help prevent damage and keep you safe during testing. Features such as waveform save and screenshot save add convenience for documentation and sharing results, making it ideal for DIY enthusiasts and professional technicians alike.

Benefits & Tips

• Use as a portable bench tool to diagnose electronics, automotive sensors, and DIY projects by combining oscilloscope, multimeter, and signal generation in one unit.
• Capture and save waveforms for recurring issues; use the screenshot/save功能 to document measurements for reporting or troubleshooting notes.
• Explore advanced oscilloscope options such as XY mode and afterglow mode for deeper waveform analysis and persistent traces, with the built-in signal generator aiding quick test signal creation.
