If I recall correctly, DMM version does not do pF.  That is why I got DE-5000 LCR Meter.
[/size]
DE5003-5004 goes down to 0.1pF(±2%+20) and 10nH(±3%+20)
DE5000 goes down to 0.01pF(±1.2%+5) and 1nH(±2.5%+5)
so the probes you use will make a big difference in the measurment accuracy !

If you want to do right LCR measurements by this meter, use this thing.

I have compared readings from this device without wirings and readings from LCR meter based on ES51919 with kelvin probes and got very good results.

That Nagant looks familiar.  Are you Gunboards.com member?

Actually DER EE DE-5003 and DE-5004 only goes down to 3.0pF with a resolution of 0.1pF (±2.0%+20) and down to 0.3µH with an resolution of 0.1µH (±3.0%+20) according to specifications: https://www.deree.com.tw/de-5004-digital-multimeter-lcr.html#specification_tab

Does anybody know where to buy DER EE DE-5004? I can't find it for sale online at eBay or elsewhere.
Has it been discontinued?

may be you can ask directly the manufacturer
https://www.deree.com.tw/index.php?kw=5004&lang=en&modelid=1&c=content&a=search
Thanks, but I have tried to contact them both via their online contact form and via email, but they don't reply.
The only reply I got was an auto reply right after I filled out the online forum, which said "Dear...., We will respond to your inquiry as soon as possible".
But since then I have heard nothing and it has been two weeks now. So I also tried to send them an email to deree@deree.com.tw, but they do not reply to that either, not even an auto reply.
Completely useless customer support.

Try these:

https://www.jredfox.com/index.php?main_page=product_info&products_id=902009

https://www.taiwantrade.com/product/de-5004-digital-multimeter-lcr-1347664.html

(NAWTS)

It does seem to be out of stock at a few vendors, the DER EE site doesn't mention if it's discontinued   :-//

Thanks, but this web shop raises a lot of red flags and seems like a scam website. I have never heard of them before and it's hard to find any info about them if your google their site name.
And the only contact info on their website is this questionable e-mail address sunny_service@trade7686.com with not relation whatsoever to the website name jredfox and the e-mail address in only inserted as an image which you can't click on to send an e-mail.
If you google ths e-mail adress all the first his are to websites talking about fraudlent websites. And these fraulent websites mentiond afe other "webshops" than jdredfox.
And there's no, phone number or physical address. The company address should always be included on legit web shops.
It doesn't even say in which country this company belong.
The tiny black and white VISA, PayPal, MasterCard and Maestro logos at the bottom also seems highly questionable.
For example they don't use the official VISA point of sale graphics required by VISA on POS sites: https://usa.visa.com/run-your-business/accept-visa-payments/posguidelines.html

Maybe the reason this is the only website with this product listed is because it's a scam website with no real products pf any kind in stock.
