ZOYI ZT-703S Oscilloscope Multimeter
A professional 3-in-1 handheld diagnostic instrument combining a 50MHz digital oscilloscope, 25,000-count True RMS multimeter and signal generator. Designed for field engineers, automotive diagnostics, electronics repair and workshop troubleshooting.
Three Professional Test Tools in One
The ZOYI ZT-703S combines waveform capture, accurate electrical measurement and signal output functions in one compact and portable instrument. It allows technicians to examine signals, measure circuit values and perform practical troubleshooting without carrying several separate devices.
Its 3.5-inch IPS colour display, rechargeable 6000mAh battery and USB-C charging make it suitable for workbench testing, mobile repairs and on-site diagnostic work.
50MHz Oscilloscope Capture and examine waveforms with a sampling rate of up to 280MSa/s and Auto, Normal and Single trigger modes.
True RMS Multimeter Perform electrical measurements with a clear 25,000-count digital multimeter display.
Signal Generator Generate waveform output for circuit testing, signal tracing and electronics diagnostics.
Portable diagnostic solution: The ZT-703S allows engineers and technicians to view waveforms and take multimeter measurements using one handheld instrument, making it practical for troubleshooting equipment in locations where a full-size bench oscilloscope is unavailable.
