Uni-Trend UT81B Review

1 Comment »

I was looking for a decent handheld oscilloscope/meter and eventually ended up buying the UT81B from Uni-Trend. There isn’t much information available about this model so I decided to do a small review of it.

Let’s start with some basic specifications from the manufacturer:

  • 8MHz bandwidth
  • 40MS/s sample rate
  • adjustable trigger (level and slope) with single-shot mode
  • voltage, current, resistance, capacitance and frequency measurement
  • 10 screen memory
  • 160×160 monochrome display with backlight
  • USB connection

Specs seem quite good for a handheld device and it should accurately display signals up to 4MHz. Time to check it out!
