Description

The ZOYI ZT-703S is a professional 3-in-1 handheld instrument combining a digital oscilloscope, a True RMS multimeter, and a signal generator — built for automotive, industrial, and electronics repair diagnostics.

Instead of carrying three separate tools, technicians can switch between oscilloscope and multimeter modes with a single button press. The dual-channel oscilloscope captures fast-changing signals at 280MSa/s, while the built-in signal generator lets you inject test waveforms directly into circuits for diagnostics — a feature usually only found in bench equipment, not handheld tools.

Why Choose the ZT-703S?

Rated CAT III 1000V in multimeter mode, the ZT-703S is engineered for professional-grade safety in demanding electrical environments. Its 3.5-inch IPS color display gives clear waveform visibility even in bright daylight, making it a reliable field tool for automotive technicians, electronics repair shops, and industrial maintenance teams in Karachi.
