ZOYI ZT-706S 3-in-1 Handheld Oscilloscope Multimeter
Measure electrical values, inspect waveforms and generate test signals with one compact instrument. The ZOYI ZT-706S combines a dual-channel digital oscilloscope, a high-resolution True RMS multimeter and a multi-waveform signal generator.
Three professional test tools in one
The ZT-706S is designed for technicians who need a portable oscilloscope multimeter for workshop and field use. It reduces the need to carry separate instruments and allows you to switch quickly between waveform analysis, electrical measurement and signal output.

50MHz dual-channel handheld oscilloscope
Use two oscilloscope channels to compare input and output signals, inspect timing relationships and diagnose intermittent faults. Normal mode provides up to 200MSa/s sampling, while high-speed mode increases the sampling rate to 280MSa/s for signals above 30MHz.
One-key AUTO setup helps stabilise unknown waveforms quickly. Auto, Normal and Single trigger modes are available, with rising-edge and falling-edge triggering.
- 50MHz oscilloscope bandwidth
- Two input channels: CH1 and CH2
- 10ns/div to 20s/div time base
- 20mV/div to 10V/div vertical sensitivity at ×1
- AC and DC input coupling
- ×1 and ×10 probe settings
- Y-T, XY and Roll display modes
- FFT spectrum, persistence and cursor measurement
- Vpp, maximum, minimum, RMS, frequency, period and duty-cycle readings
66,000-count True RMS multimeter
The integrated digital multimeter gives detailed readings for electrical installation work, electronics repair and equipment maintenance. Automatic and manual range selection are supported.
- AC and DC voltage measurement
- AC and DC current measurement
- Resistance and capacitance measurement
- Frequency measurement
