Handheld oscilloscope with 3.5" color LCD screen

WUQ

WUQ HDS272S 3.5" 70MHz 3-in-1 Oscilloscope Measurement Tool

SKU CH-D66B-Y07EC

A 3.5" handheld oscilloscope, multimeter and waveform generator with 70 MHz bandwidth, 250 MS/s sample rate, 10,000 wfrms/s refresh rate and a 4400 mAh 18650 battery for about 6 hours of field use

  • TypeTest Instrument & Gauge Parts
  • 70 MHz bandwidth captures fast signals accurately
  • 3-in-1 oscilloscope, multimeter and generator in one tool
  • 5" colour LCD readable outdoors and in dim light
  • 4400 mAh 18650 battery runs about 6 hours continuously
  • 20 000-count DMM adds precise voltage and current measurement

3-in-1 Oscilloscope for Field Diagnostics

The WUQ HDS272S combines a 70MHz bandwidth oscilloscope, a 20,000-count multimeter and a waveform generator in one handheld unit. Two oscilloscope channels plus one generator channel cover automotive injector tests, sensor troubleshooting and educational lab work. A 3.5 inch colour LCD remains readable outdoors and the compact body fits a single hand for mobile use.

Sustained Capture Performance

A 250MS/s sample rate and 8K record length maintain signal fidelity during long acquisitions. The 10,000 wfrms/s waveform refresh rate keeps the display responsive when monitoring intermittent faults over extended periods. Vertical sensitivity from 10mV/div to 10V/div with DC, AC and ground coupling adapts to both low-level sensor signals and higher-voltage circuits without range switching delays.

Battery-Powered Portability

A standard 4400mAh 18650 lithium cell delivers about six hours of continuous operation and can be swapped in the field without tools. The single-bay design means one spare battery restores full runtime, avoiding proprietary pack delays. Menu navigation is straightforward, though users unfamiliar with combined instruments may need time to learn the generator-triggering workflow before relying on it for critical diagnostics.

Questions about this item

How much heat or noise does the HDS272S produce during a full six-hour session on its 4400 mAh 18650 battery?

The handheld unit runs silently with no fan; warmth stays low because the 70 MHz front-end and 250 MS/s sampler draw modest power from the single 4400 mAh 18650 cell, giving roughly six hours of continuous use.

What probes or leads must I already own to use the oscilloscope, multimeter and generator functions?

The 2+1 channel oscilloscope needs BNC probes for the two scope inputs, the 20,000-count DMM requires standard banana test leads, and the built-in waveform generator uses the same BNC output — all three interfaces are industry-standard connectors.

Will the 70 MHz bandwidth and 250 MS/s sample rate let me debug legacy 5 V automotive sensors alongside the HDS272S?

Yes — the 10 mV/div to 10 V/div vertical range with DC, AC and ground coupling covers classic 5 V sensor signals, while the 10,000 wfrms/s refresh rate catches intermittent glitches on older injector or ignition coils.
