Part true minus the expensive alternative / cost bit I actually do have the pico model I bought years ago before knowing they were on aliexpress, it is the same board, just a rebadge The best current clamp I've seen for the money is micsig's CP2100A for about $200 and goes up to 800 KHz or CP2100B for about $400 and goes up to 2.5 MHz These blow this design out of the water although it is still good for a dmm and single use / point testing and now is only $60 bucks or so The micsig's only came out in the last 2 years or so while this design has been around for 5 years or so? I've been using several CP2100B for multi phase power and they all work fantastic |

Plus the unbelivable building quality of the micsigs. I don´t know how they managed it, but you wouldn´t believe they´re so cheap when you don´t know their prices. 800khz and 2.5Mhz....Look around, at which price you normally do get this. Unbelievable. |

Looks very good if you need the frequency. That seems to be the only significant positive. (can work around zero offsets) Noise level is about the same, 4x cost & needs external 5V. I have seen reviews indicating some of the better clamps having 1/10 the noise levels of this? How does it handle magnetic fields??? Does it self magnetise on high DC currents, if NOT then a BIG plus! Oh & the Hantek design is ancient! Looks like based on clamps from the 80-90's just using more modern components. Cheers, John. |

Martin could probly answer that, you can see the noise levels here https://www.eevblog.com/forum/testgear/micsig-current-probe-cp2100b-tests-and-comparing/ |

Noise no better than CC-65 from that $400 unit. Much better Freq! though, but for a bit $ more I would hope the noise would be a bit less! John |
