HANMATEK 3 in 1 Handheld Oscilloscope Multimeter 100MHz - Portable

Our review of the HANMATEK 3 in 1 Handheld Oscilloscope Multimeter finds it best suited for students, hobbyists, and field technicians who need a compact, accurate instrument that combines an oscilloscope, multimeter and waveform generator. The single biggest reason to buy is its balanced mix of performance and portability: a true dual-channel oscilloscope with up to 100MHz bandwidth, deep 8K memory and a 3.5' color screen in a palm-sized unit that runs on a rechargeable battery. For anyone who needs faster waveform updates and reliable measurement capture on the go, this device delivers.

Key Features

• Dual-channel 100MHz oscilloscope: Provides high signal fidelity and enough bandwidth for most electronics troubleshooting and automotive signals.
• 3 in 1 instrument: Combines oscilloscope, DMM and waveform generator so you can measure, diagnose and inject signals without swapping gear.
• High refresh and deep storage: Waveform refresh up to 10,000 wfms/s and 8K memory depth help capture low-probability or transient events.
• Automatic measurements and XY mode: Seven automatic measurement types and one-touch auto setup speed routine testing and debugging.
• Portable interface and battery: 3.5 in color TFT, palm-sized layout and built-in rechargeable battery with USB Type-C charging for field use.

Who It's For

The HANMATEK is ideal for electronics students, makers and field service technicians who need a capable yet portable oscilloscope with multimeter functions in one handheld package. Its dual channels and 100MHz bandwidth make it strong for circuit debugging, automotive signal checks and lab tasks where bench equipment is impractical.

Less suitable for high-end lab engineers who need very large screens, advanced trigger options or extremely deep memory for long captures; those users should look to benchtop models. Beginners should expect a learning curve when using oscilloscope features despite the one-touch auto setup.

Pros & Cons

Pros

• Compact 3 in 1 design reduces the number of tools needed for field troubleshooting.
• Accurate measurements with a capable chipset and useful automatic measurement displays.
• Fast waveform updates and 8K storage make capturing rare events practical.
• USB Type-C rechargeability and 3.5 in screen make it convenient for handheld use.

Cons

• Small screen and compact controls can feel cramped for extended bench use or complex setups.
• Some users report a learning curve when accessing advanced oscilloscope functions.
