AOS03 Handheld Oscilloscope Multimeter – 2 Channels, 50MHz Bandwidth, up to 280MS/s, 250,000 wfm/s, 128KB Record, 3-in-1 Scope + Multimeter + Signal Generator
AOS03 Handheld Oscilloscope Multimeter — 2-Channel 50MHz True RMS Diagnostic Tool
The AOS03 is a compact handheld oscilloscope multimeter designed for electronics diagnostics, field troubleshooting, and repair work where waveform visualization and measurement functions are required in one device. It combines a 2-channel digital oscilloscope, a 25,000-count True RMS multimeter, and signal generation capability within a rugged ABS/TPE enclosure.
A large 3.5-inch IPS full-view color display ensures clear waveform viewing from multiple angles. The oscilloscope supports up to 50MHz bandwidth, listed sampling rates up to 280MS/s, and a high waveform capture rate, enabling observation of dynamic signal behavior during diagnostics.
Powered by a rechargeable 18650 battery, the device offers portability for laboratory, service bench, or on-site maintenance tasks, combining multiple measurement tools into a single handheld instrument.
Waveform analysis with portable handheld convenience.
25,000-count precision electrical measurements.
Wide viewing angles for waveform inspection.
18650 battery for mobile diagnostics.
