Be sure to report back either way. I am curious who their official reseller is. |

I'm also interested in your experience with the TH2830 once you get it :) |

I emailed them this: "I’m interested in purchasing a TH2830 LCR meter. I live in the United States. Where should I buy the meter from? I’m also curious, I assume the firmware is upgradeable, where can I get the newest firmware from?" Their response: "If you are interested in our 2830 machine, you can buy the machine directly with us. The firmware is upgradeable, if you need the latest firmware version, you can ask us for it." Naturally, they didn't include a price or a link for the firmware. 🙄 So, I responded asking for a price quote, and a link for the firmware. We'll see what they say. I also filled out a price request on their website. It appears their only official seller for the US, is themselves. I hope their price isn't crazy. I found a reputable seller on aliexpress that offered me the TH2830 with DHL express shipping for $780. That's pretty tempting. I'm used to dealing with Siglent, who is usually really good about making the firmware available. This whole "ask us for it" thing rubs me the wrong way. --- Quote from: pope on May 22, 2023, 10:19:48 am ---I'm also interested in your experience with the TH2830 once you get it :) --- End quote --- lol me too. 😉 I'll definitely post my experience with it. Thanks, Josh |

I have the ET4410. See my other post for pictures. I don't have the DE-5000, so I can't compare. But I like it. It starts fast and is easy to use. Display is good. Price is what I could afford for hobby use. Maybe for pro use, I would recommend a more expensive meter. Depends on actual needs. Resistance is very consistent compared to my Agilent 34401A. They seem to be within 0.02% of each other (measured a batch of resistors a few different values). The 34401A has higher resolution and more digits, so sometimes it's more useful for resistance measurement (but that's beginning of metrology territory). An example (100R 0.1% resistors): ET4410 33401A 99.97 99.9502 99.98 99.9673 100.00 99.9802 100.02 100.0007 100.02 100.0041 The Agilent isn't calibrated, so I don't know which instrument to trust more, but this is very little difference and it's consistent also in other ranges. The Kelvin clips supplied with the ET4410 can't be compared with expensive clips, but work actually fine and are better than some really cheap ebay Kelvin clips that I use with the 34401A. If you are using it professionally, then it's probably worth buying some pro clips. Now I want to get some better Kelvin clips for the 34401A, the ones I have are actually crap. |

Between you, Martin72, and the tediousness of communicating with Tonghui, I'm tempted to get the ET4410. I can get it for $232. But, still, the fixtures, etc. I heard back from Tonghui: "The price for TH2830 is $ 965 (exclude the transportation expense), the machine is already with the latest firmware." I responded: "Why is it less expensive on aliexpress? They told me $780 with express shipping. also, I like the Siglent company. They make firmware and support easier. It is odd to me to make the firmware hard to get. Unfortunately, Siglent doesn't make LCR meters." Now I wait again and see if they respond. In the meantime, another seller with a decent rating on ali has offered my the TH2830 for $650 with DHL shipping. I might just go for that. 🤔 Thanks, Josh |
