A two-channel 50 MHz handheld oscilloscope at 250 MSa/s with a 10,000 waveforms-per-second refresh, an independent 4½-digit true RMS multimeter, and a USB-C port that shows saved images and CSV waveforms as a flash drive.
The bottom line A thoughtful handheld for people who analyse afterwards: fast refresh, CSV export, reference waveforms and a true RMS meter. Its short record length limits long captures, and its probe count differs between text and photograph.
The HO52 listing, bullet by bullet
Five bullets: a scope mode with up to 10,000 waveforms per second, two channels, 50 MHz, 250 MSa/s, an 8,000-point record, cursors, seven automatic measurements, X-Y and one-key auto set; a 4½-digit true RMS meter mode with auto range, AC 750 V and DC 1000 V, and inputs independent of the scope; a USB-C port for power bank supply, charging and a computer link that shows the device as a flash drive; storage of settings, reference waveforms, images and CSV files, self-calibration and six measurements on screen; and a box with carry bag, probe, adapter, USB cable, meter lead, manual, CD and calibration pen.
Refresh rate against record length
10,000 waveforms per second, 8,000 points each. A fast refresh shows intermittent glitches as they happen. A short record limits how long a captured window can be at full detail. The HO52 favours the first.
CSV on the HANMATEK
Saving a waveform as CSV means it can be opened in a spreadsheet or analysis tool. Mounting as a flash drive removes any need for special software to retrieve it.
Probes on the HO52: one in the text, two in the photograph
The box list names one oscilloscope probe, and the product photograph shows two. Using both channels needs two, so the count is worth confirming with the seller.
Availability
At the last look-up, the German, French, Italian and Spanish Amazon stores were asking 130 € to 150 €.
It is sold in the American and British Amazon stores as well, in their own currency, which the euro figures above leave out on purpose.

Where it earns its place, and where it falls short
Strengths
A waveform refresh rate of up to 10,000 waveforms per second
An independent 4½-digit true RMS multimeter input with auto range
USB-C connection that appears as a flash drive for saved images and CSV waveforms, and self-calibration
Compromises
An 8,000-point record, short beside the 128K of the cheaper BSIDE handheld here
The box list names one probe while the photograph shows two
No trigger modes described

Questions makers ask before buying
How are waveforms saved on the HANMATEK HO52?
The fourth bullet says it stores 4 sets of settings, 4 reference waveforms, 4 images and 4 CSV waveforms; the third says a computer sees it as a USB flash drive to read them.
How many probes come with the HO52?
The fifth bullet lists one oscilloscope probe, with a multimeter lead and a calibration pen. The product photograph shows two probes, so the count is worth confirming.
