Default Recommendation: Good value-for-money LCR meter?

Hello:

I'm looking for recommendation for a good value-for-money LCR meter. Should have had one of these a zillion years ago, but don't. Right now what's prompting the need are a couple of speaker repairs/restoration. Most specifically I need to measure capacitor values. Inductance measurement would be handy, too. Of course I already have some good meters to measure resistance, voltage...

Could be new or used. Something smaller, more compact would probably be preferred to a big lab/bench tester.

Any suggestions are welcomed.

Thanks,

- SJ

I'm very happy with the AADE L/C Meter (Link).

If you want a real LCR and not a toy, I recommend the Der EE DE-5000. Around $90-160 depending on the included options (USB logging, SMD tweezers, aligator clips, etc). With the most common option combination (everything but the USB adapter and guard adapter) coming in at $112 shipped. The reason I say this is a TRUE LCR meter is that its able to measure things like ESR, D (a better indicator of capacitor health), Q, theta, inductanc, etc It has DC/100/120/1k/10k/100k Hz test frequencies (unlike others which give you a single point measurement at best). It can do series/parallel measurements. You can measure resistance at various frequencies, it has up to 0.2% precision on resistance. 20,000 count display.

L: 20.000uH ~ 2.000 KH
C: 200.00pF ~ 20.00mF
R: 20.000 Ohms ~ 200.0 MOhms
DCR: 200.00Ohms~200.0MOhms

It also has automated sorting capabilities with bins as small as +/-0.25%

me too.

imagine my (pleasant) surprise when i compared it's readings to a recently calibrated, expensive hp analyzer and they agreed EXACTLY on sample caps from 1uF to 10pF.

i just wish the display was a little easier to see.

Thanks everyone. That helps a lot. That's well within budget.

The meter could be new or used.

Sorry to necropost but a seller on ebay has the Der EE DE-5000 with the optional tweezers, optional short aligator leads and optional guard lead for $82 shipped to the USA. Thats about $30 cheaper than its previous lowest price.

Der de 5000 LCR Meter with TL 21 TL 22 TL 23 | eBay

I will post a full review when it comes in.

Thanks Pedro.

That did it, I bought one without the guard.

Regards

Late to the post. I just one of these: DIY Meter Tester Kit For Capacitance ESR Inductance Resistor NPN PNP Mosfet M168 - US$12.22 and I am quite impressed! E

For loudspeaker impedance measurement, you might want to consider the development board of the Analog Devices AD5934 -- http://www.analog.com/static/importe...L_AD5934EB.pdf

I think that the price is $50 to $60. You can also use it to measure R, C and L. I believe the software will allow you to measure gain and phase too, so you could use it in analyzing crossover networks.

(The purpose of the AD5934 was to measure corrosion (potential structural weakness) in aircraft, fuel cell impedance, spectroscopy etc., etc.)

There are enough audiophiles at Analog Devices that one of the fellows wrote this application note:
