HANMATEK 3 in 1 Handheld Oscilloscope Multimeter HO51 - Portable Test

In this review the HANMATEK HO51 is judged as a compact, beginner-friendly multi tester that combines an oscilloscope, multimeter and signal generator in one handheld unit. The single biggest reason to buy is its three-in-one functionality, which replaces multiple bench instruments for field troubleshooting and quick lab tasks while remaining portable and easy to carry. It is best for hobbyists, students and technicians who need basic yet accurate waveform and electrical measurements without a full bench setup.

Key Features

• Three-in-one functionality: Combining an oscilloscope, multimeter and signal generator saves bench space and lets users switch between tasks quickly.
• 50 MHz bandwidth oscilloscope: The scope delivers up to 50 MHz bandwidth with a 200 MS/s sampling rate for clear waveform analysis on common circuits.
• Advanced multimeter modes: Measures voltage, current, resistance, capacitance, continuity and diode checks for broad troubleshooting needs.
• Built-in signal generator: Outputs sine, square, triangle and custom waves up to 1 MHz so you can inject test signals without extra gear.
• Portable design and display: At 0.5 kg with a 3.5 in color TFT screen, it is easy to carry and provides a readable, intuitive user interface in the field.
• PC connectivity and accessories: USB connection and included probe, test leads and cable simplify data transfer and initial setup.

Who It's For

The HANMATEK HO51 is ideal for students, DIY electronics hobbyists and entry-level technicians who need a versatile instrument for basic circuit debugging and education. Its portability and combined features are particularly useful when space and budget are limited and when occasional signal generation is required.

Serious bench engineers or those who need very high bandwidth or advanced oscilloscope analysis features should look elsewhere; this unit shines at convenience and value rather than replacing high-end lab instruments. Users requiring very long battery life or extensive professional software integrations should verify compatibility before committing.

Pros & Cons

Pros

• Compact three-in-one design reduces the need for multiple devices during field repairs.
• Accurate oscilloscope performance with 50 MHz bandwidth and 200 MS/s sample rate for typical electronics work.
• Useful built-in signal generator up to 1 MHz for quick signal injection and testing.
• Comes with essential accessories and USB PC connectivity for data transfer and control.

Cons

• Battery life is mixed per user reports, so long sessions may need USB power or spare batteries.
• Some users note a learning curve for beginners despite the simple interface.
