In this article, we’re sharing the Hantek 2D72 handheld oscilloscope information’s. It’s a 3 in 1 device that includes a two-channel oscilloscope, a multimeter, and a waveform generator, all packed into one small, portable unit. Size-wise, it’s just a bit bigger than a regular multimeter.
I got this device from Banggood. Handheld oscilloscopes like this one are really helpful in certain situations, such as testing live mains electricity. In those cases, using a regular oscilloscope could damage the internal parts or even cause it to fail completely, which would be a very expensive fix.
When you’re troubleshooting electronics, you often just want to check if a signal is there, rather than taking super accurate readings. That’s why handheld devices like this are so convenient—they let you do quick, simple tests easily. It also helps that the 2D72 is very affordable for what it offers.
The 2D72 is the top model in Hantek’s D-series. It’s currently being sold for just $179 on Banggood, which is a really good price if it performs well. If you don’t need the full 70 MHz bandwidth, you could go for the 2D42 model, which offers 40 MHz and saves you about $30. Just note that only the D-series includes the waveform generator, not the C-series.
In my opinion, the waveform generator is worth the extra $30, so it makes sense to choose the D-series. The oscilloscope comes in a hard-shell case and includes two BNC-to-banana cables, multimeter test leads, and one oscilloscope probe. I’ve already tested it, so my set looks a little messy now.
It’s a bit of a drawback that only one oscilloscope probe is included, but that’s not a big deal since these low-bandwidth probes are cheap and easy to find. Many people already have a few lying around, so buying extras won’t be a problem if needed.
When you power on the device, you might notice a bit of screen glare, but it becomes clearer once it’s running. The oscilloscope boots up very fast, which suggests it doesn’t use a full operating system. That means it’s built to run efficiently and directly on the hardware, which usually leads to better performance.
One handy feature is that it remembers the last mode you used, like the multimeter or waveform generator, and returns to it when you power it back on. The 2D72 has a 70 MHz bandwidth and a rise time of 5 nanoseconds, which is decent for its price range. It samples at 250 million times per second on one channel, which is enough for most simple signal testing. It also has input protection up to 150 volts RMS, which adds to its safety for general use.
