ZT-702S 2-in-1 Oscilloscope Multimeter - Portable 2.8in IPS Tester

In this review of the ZT-702S 2-in-1 Oscilloscope Multimeter, the bottom line is simple: it is a compact, wallet-friendly diagnostic tool best suited for technicians and hobbyists who need both an oscilloscope and a multimeter in one portable unit. The single biggest reason to buy is the combination of a clear 2.8in IPS color display and practical measurement range that handles both waveform inspection and standard multimeter tasks, all with rechargeable power and useful features like data storage and a built-in 4V/1kHz square wave output.

Key Features

• 2.8in IPS display: The full-view color screen makes waveforms and numeric readings easy to read in most lighting conditions, improving measurement confidence.
• Dual oscilloscope and multimeter modes: One-button switching lets users capture waveforms or take 9999-count multimeter measurements without changing tools.
• Oscilloscope performance: Single-channel 10MHz bandwidth with up to 48MSa/s real-time sampling and time base accuracy for basic signal troubleshooting.
• Comprehensive multimeter range: Measures DC/AC voltage and current, resistance, capacitance, frequency, and temperature, covering common bench and field tasks.
• Rechargeable and durable: Built-in 2000mAh battery with USB Type-C charging and an ABS+TPE double-injection housing for better grip and protection.
• Useful extras: Features such as data storage, export, square wave output, adjustable backlight and selectable language enhance day-to-day usability.

Who It's For

The ZT-702S is aimed at electronics hobbyists, automotive technicians, and small workshop users who need a portable diagnostic instrument that combines basic oscilloscope functions with a capable multimeter. Its 10MHz bandwidth and practical probe outputs make it suitable for inspecting sensor signals, audio paths, and switching waveforms encountered in automotive and industrial gear.

Prospective buyers who require high-end lab-grade specs, multiple oscilloscope channels, or very long battery runtime should look elsewhere. Similarly, professionals who need extreme bandwidth or advanced trigger and analysis features will outgrow this unit, but for many repair and troubleshooting tasks it is an efficient all-in-one choice.

Pros & Cons

Pros

• Clear IPS display that presents waveforms and numeric data legibly.
• Versatile dual-mode design that reduces the need to carry separate tools.
• Rechargeable battery with USB Type-C allows field use and easy charging.
• Solid safety and protection features, including double fusing and high input tolerance.

Cons

• Interface can be a bit perplexing at first for new users despite being feature rich.
• 10MHz bandwidth limits work on higher-frequency electronics compared with larger bench scopes.
