HANMATEK News-Stay Updated with Newest

Discover the best 2026 benchtop oscilloscopes for power supply, MCU/Arduino debugging, and multi-signal analysis. Hanmatek picks: DOS1102 (110MHz), DOS1202 (200MHz 2CH), DOS1104 (110MHz 4CH). Reliable, easy-to-use, great value for faster repairs.

Compare 2-channel vs 4-channel benchtop oscilloscopes: 2CH for basic tasks, 4CH for multi-signal debugging and faster embedded system analysis. Hanmatek models (DOS1102/1202/1104, AHO814) offer reliable, high-performance options for any budget or project complexity.

Discover how the Hanmatek AHO814 4-channel 100MHz smart touchscreen oscilloscope enhances embedded system debugging. Analyze signal integrity, power, protocols, and multi-signal correlation with a portable, intuitive, high-performance tool.

The Hanmatek DOS1104 is a 110 MHz, 4-channel digital oscilloscope with true simultaneous capture, 1 GSa/s sampling, and a 7-inch display—ideal for embedded systems, power electronics, industrial control, and protocol analysis at great value.

The HANMATEK DOS1104 is the best-value 110 MHz 4-channel bench oscilloscope of 2025 at only €289 — but like 99% of bench scopes, its channels are NOT isolated (all grounds are tied together). This article explains exactly when that’s dangerous, the 5 most common “blown scope” accidents, and the safest, cheapest way to do floating/offline measurements in 2025: pair the DOS1104 with a €69 differential probe. Real tests, comparison tables, and Black Friday bundle (free SF3 stud finder) included.
