Hi
This is the first time that I want to buy a 6.5 Digit multimeter, so any feedback is welcome,
My budget is limited so I have these models that are with in my budget.
From Chinese brands we have these models
HDM3065B from hantek that's very similar to keysight 34461A
GDM-9061 from GWinstek
SDM3065X from siglent it's almost a copy of lecroy T3DMM6-5
DM3068 from Rigol

Any other Chinese brands or lower cost brands that you Maye know and suggest?

Which model do you choose? why?

Unless you really need the graphical features I would not purchase any of those, I would find a gently used 34401A. You can get two or three for the price of one new on your list.

I have had a couple of those lower cost DMMs Instek 8251 etc. I found when there was a good Fluke or 34401A on the bench at the same time I would use the wannabe at absolute last resort. I have 3x 34401A on my bench and they report the same measurements +/- the LSD even after not being calibrated for years. The stability over time is just one aspect there are others like noise that make using a first rate DMM(even an old one) a better experience.

Considering the unseasoned and questionable references used in the meters above, don't expect much accuracy a year after you purchase it.   I have a 25 Year old Fluke 8842A with the LTFLU reference and I would not be surprised if it measures 10Vdc more accurately than the above meters a year after you purchase it.

I see your in Canada, Kijiji sometimes has fair deals if your patient, I picked up two of my Agilents locally one for a really good price.

What work do you want to do with this,  at 6.5  digits you have to consider calibration prices too

An 34401a  is an oldie but a goodie and schematics exists, if you can snatch them at a low price, if they work, you do a capacitor recap and re-calibrate them +/- 200$ cad added (160$ calibration)

Same for 34410A  if i remember, not sure for the 34411A

Some Keithley 2000 series had some reverse engineered too

The web site Xdev's  had many repairs and infos ...


For the others, you have to ask the calibration facility if they can do them (Brand and models)  and some of them Graphical and or normal models can have quirks in their firmware,  do a search before ...

You have some meter charts / comparisons here, do a search


At 6.5 digits  they are not "toys"  and when you say "budget is limited"  you have to ponder a few things first

The LeCroy is simply a rebadged Siglent. I don’t know if they gave it special firmware, but I kinda doubt it.

I personally don't see the point of having 6.5 digits if the meter is not accurate and stable.  Lower cost meters have been shown to not do quite as well as their A-brand peers in this regard, especially over time.  If you do buy a lower-cost version, make sure you get one that is adequately supported by the manufacturer and seller.  A three-year warranty and a place in-country to send it for service would be the minimum I'd accept.

Just FYI, the Hantek is an unrelated knockoff (appearance-wise) of the Keysight, but the Siglent is not a 'copy' of the LeCroy.  Siglent manufactures them for LeCroy, so they are virtually the same meter.  I don't know if there is any actual performance difference between the two, but I think the published specs are the same.

The Siglent and Rigol meters are fairly popular and I gather that most people are relatively satisfied with them despite a few issues arising.  You can find threads about each if you search this forum. 

Don't overlook the BK Precision 5493C.
