I think you are very picky  ?    and this thread is a going nowhere one ... seeing your reactions.

I guess the op's definition of "proper tool" is not cheap plastic feel, and also maybe just judging only from the look like built from metal/sturdy frame and etc.

If that is the case, I agree, this thread is going no where as the op probably doesn't even know what to look for apart from the device's look & feel only.  :palm:

There are several places that carry DE-5000 in EU, for 180-190€+ TAX.
While that might not seem cheap, importing stuff and having to deal with vendor in far away country, not knowing what will you get etc..
I would personal get one of those in EU to have warranty,all consumer protection and 2-3 days delivery.

Even at 220 € with tax, DE-5000 is better than anything else up to 500-600€...

Thanks to all, your opinions are very helpful. Long story, short: There are no real affordable alternatives which hold up to the DE-5000.

Looks like I just save up,and buy one of those.  :-+

Its cheaper available:
https://www.ebay.de/itm/DER-EE-DE-5000-Handheld-LCR-Meter-TL-21-TL-22-3-SET-from-JPN-New-F-S-Authentic/383643184292?epid=24032160007&hash=item5952ea6ca4:g:1wMAAOSw0K5eKAMr
ca. 96€ with the risk of additional 19% import tax. And the shipping isnt DHL Express so you dont have to pay the DHL Express "service" fees.

Add one more to the list of guys very happy with the DER-EE. Love mine for sure. It is in my list of most used instruments also.

As I wrote it before, got mine still at work and let it compete with our calibrated, much more expensive LCRs....
It do a fantastic job so far.
But also as our keysights and GenRads, it got problems to measure power coils accurate - but this a "natural" behaviour, as all the LCRs on the market couldn´t deliver real current flowing to the DUT.
For this cases, we got a self-build solution with IGBT and µC, delivering currents up to 200A...

Sounds dramatically, but it isn´t... ;)
In fact, the source for it won´t need more than 300mA to deliver...
The secret, sshhh....Caps  ;D

You could spend more money the Hantek TO22.  It has a nicer display and uses Li ion batteries.   It appears to have the ability for Kevlin inputs, but does not come with leads or adapters to utilize them.

Oh come on......another one?

I have the DE-5000. This one looks freakin nice, although I'd probably get the higher freq version.

Come on what  ?   

DE-5000 does 100khz and priced way lower than the TO11 TO22, the lack of kelvin probes is a no go, for that price you have a De-5000 kit with an carrying case and in some instances (Ebay)  without the case you can have all the probes and the optical communication interface  ...


You have an M4070 lcr meter, seems to do a good job too, even do up to 500khz for capacitor and 360khz for coils ???

There's an m4070 teardown on the web

Are you sure that's a real LCR meter?  It looks like an overpriced AADE style LC tester with an ohmmeter added.

hum   can't find it    but its floating on the web somewhere

Some said it was like an mlc-500 lcr,    anything is possible  ....   this is the internal mlc-500 board   see the 3 holes ...

and a discution
https://groups.io/g/QRPLabs/topic/mlc_500_lc_meter/6379464?p=



And to end this lengthy discution, a real lcr ???   

I had an Sencore lc102   is it a real lcr ??  it was charging a capacitor up to 1 kilovolts,  it could do up to 20 henrys and 20 farad.  Sold it,  wanted more available place on the bench

I had an Phillips pm6304 lcr too ...  same thing, needed more place ...  i was even trying to build an dc offset option board, i have a thread here.


Now i have an De-5000    is it an lcr ???  It does what i want,  thats all

If you do a check list of all the lcr brands out there :  what will you buy in the end ?  a 100$ one, a 200$, up to 2k $$$ or more ?  overpriced ones or cheaper ones ?

That board certainly does not look like an LCR meter circuit.  3 holes, so what  :-//

No, doesn't appear to be (can't measure D/Q, etc.)

Now that is an excellent LCR meter!

TI has published a reference design "LCR meter analog front end reference design"

https://www.ti.com/tool/TIDA-060029

Following text is copied from TI site:

This reference design, TIDA-060029 demonstrates an analog signal chain solution for LCR Meter applications using an auto balancing impedance measurement method.

Features
  • Measures wide range of components (L, C, R) with impedance values ranging from 1 Ω to 10 MΩ
  • Frequency of operation up to 100 kHz
  • Tested at 100 Hz, 1 kHz, 10 kHz, 100 kHz
  • Impedance accuracy of 0.1 %
  • Inherently stable operation of the signal chain

Come on what  ?   

I meant that as a way of implying that there is another meter I might have to buy because......I do like the lower resistance range on it in addition to the software that it uses.

As far as the kelvin cables/clips/etc, that's a non issue for me.

What are main differences between to22 and DE-5000? To me to22 looks a bit more appealing due to the color screen.

Check their specs  and do a comparaison ?

https://www.deree.com.tw/de-5000-lcr-meter.html

http://hantek.com.cn/products/detail/16180

the t011 is an 1832c
the t022 is an 1833c


They seems to have the same ranges,  i work with 12,000 uf  capacitors in banks of 2 or 4 ... have to separate them if i want to do measurements.

EDIT arr some web lag loll        20 millifarads are the top capacitor range = 20,000 uf,  i would like a 100,000 uf top range :(

The biggest difference for me is the integrated usb link in the to22, the de-5000 need an added interface, but generally have all the input dongles ...

Of course you have colors  loll


Edit :  i've seen some country have big import charges and added taxes,   it will influence the total amount in a big way ???

Your wallet will talk  loll

The lowest price i've seen for the Hantek  are 182$ usd  for the to22  on AliExpress and Banggood,  Ebay seems to follow this trend.

The DE-5000 kinda disspapeared on some websites ?

The DE-6000 is a tighter specced model, not worth the $$$ price difference


You have the ET430 series who seemed very nice too, but high priced to my taste, they seems a rebadged version of tonghui and another one (blank memory loll)

ANNND where back in a circle,   too many models to choose.


Would be nice to poke in the FW of the TO22 to see if we can hack a TO11 / 1832c  into the TO22 / 1833c, there is a started thread fo the TO11  here with a dumped FW of it.

Thanks for the detailed reply. The reason I asked is that spec != user experience. Not to mention I don't trust those specs unless verified.

In the end    it's the needed specs / capabilities   for the job(s) you need to do  versus the price you want to pay, a benchtop has it's quirks  and a hand held too  loll

You could do many comparaisons / specs / prices  all year long loll

Even a cheap 20-30$ lcr tester / parts tester  helped me to do some jobs ... and the FW and hardware is constantly evolving.


Paid up to 600$ usd for a bench lcr  and it was not enough.  Always something you need ;)

Seems to me convenience and speed is what you pay for.  Theoretically, you could do a lot of quite reasonable LCR testing with your function generator and oscilloscope, plus a DIY fixture of some kind - if there were enough hours in the day to set this kind of thing up, every time you needed it!

I just bought a spare TL-21 bought some nice kevin clip cables off of ebay and cut off the ends and soldered them onto the circuit boards of the spare TL-21 carefully.  Now after calibration I have nice long cables and big kelvin clips I can use on big GIANT CAPS!

Took my DE-5000 at home now, after several comparison between a stationary GenRad and a new bought keysight 1733C(both new calibrated).
The accuracy is really good, notifying the price, all in appx 160€(including Tax, Shipping), it is fantastic.
Instead of looking for cheaper alternatives, save your pennies until you can buy the DE-5000.
