Hi all! :)
I'm currently looking to buy my first (somewhat proper) multimeter. Given the current situation, and my limited budget, im having to choose between these two multimeters:
MASTECH MS8269
Pro'sKit MT-5211

I first wanted to buy Pro'sKit one, as it has a wider range on L and C meter. But MASTECH one look to be a better quality one. I'm mainly going to use it for bench (breadboard) measurement - so low current, low voltage. I also want one with LCR meter. Hence why these two.

And yes, i know you are probably going to say they are both bad, but for now these are my only options.
I just want ho hear your experience with these two manufacturers (if possible these two multimeters), and to know how reliable they are.

MASTECH MS8269   :-+

Anything cheap with 'Pro..' on the label, should be avoided  :scared:

There's nothing 'pro' about cheap priced test gear electronics


fwiw: I've used a few MASTECH meters and do the job well enough for the price, the leads were ok too 

Same deal with some Klein meters, good for the price

Yeah, i thought so. But how good is it when measuring for example 1-10 uH inductance?
Thanks @Electro Detective for response and advice! :-+

Inductance on some/many cheap meters is pretty much useless from my humble experience,
unless comparing with a good inductance meter, on different value coils with honest labelling etc
and noting the difference
and if the difference/s are tolerable enough for you to get the job done

I've been down that path and ended up buying a multimeter based on it's  'close enough' inductance accuracy

IIRC different frequency test signals are used depending on the inductance 

Nowadays there are some decent meters that do pretty good,
but I would still like two totally different meters that agree on an inductance value

Same deal with capacitor testing, the meters better agree close enough,
or the one that doesn't..  >:D

I also recommend the Victor VC9808 + model! Only just like mine and which I showed in the photo.
This multimeter has a wide range of inductance and capacitance measurements.  :)

I didn't really understand you? I was manly asking about the resolution and accuracy of measuring 1-10 uH 1-10 mH inductance with 20 uH 20mH range on MASTECH one.

You would have to compare some values with an accurate inductance tester and see how close it is

These multimeters have no range for measuring uH. There are range on the measurement of mH.
1-10 uH inductance it will not measure correctly.

Looking at their specs, you can't measure any inductance lower than 10uH with the Mastech - its resolution is 10uH in the lowest range.

https://www.manualslib.com/manual/986618/Proskit-Mt-5211.html

Even still, the accuracy for inductors with such low value would be quite difficult, since the leads alone would add much more than that and I don't see a relative/null button on them.

If you really need to have LCR measurements and do not need to probe high voltage circuits, consider getting a super cheap multimeter (Mastech MAS830B or MAS830L if you need backlight) and save for a better LCR meter such as the DER EE DE-5000.

Oh, the "whys" of the datasheets... The information is there not to be an axiomatic truth, but instead each speck of data must be slowly inhaled while carefully performing a deep search inside oneself to find the true metaphysical sense...

The Pro's kit has a 1uH resolution, but the measuring frequency of only 100Hz and the added inductance by the leads will surely ruin any accuracy.

Sorry my mistake, i sad 1-10 uH, i actually meant 1-10 mH range. I have a lot of radial kid of ones from old course that i desoldered and i would like to be able to measure them. Btw thanks all for responses! :D

FWIW I've never seen any high or low end Fluke or Brymen multimeter with an Inductance feature,

they obviously avoid the extra drama, and just offer a rough Capacitance tester setting, and the usual features

I don't even trust LCR meters, unless they all 'closely' agree on labelled and verified inductance values at whatever test setup stated by the manufacturer

Am I too fussy?   :-[ 

No! I think..

;D

Yes, I agree with this, I also want to add that the measurement result in this range will very much depend on the active resistance of the inductance itself.  :)

I don't even need exact inductance measurement, only rough one. I'm mostly going to use inductors in some kind of combination with capacitor.So there fore, i can correct, or compensate for wrong inductance reading by placing different capacitor. Anyway thanks all for replies!

Iv just noticed that MASTECH MS8269 has 200mA and 10A range. Is it accurate when measuring 200mA-2A curents?

Read the specs.

They tell you the accuracies of inductance, current, everything.
