LCRZ Meters, Chart ?

That said, the Hantek 1833C has worked fine for me so far, as I mentioned, so I have no real regrets other than I typically don't care for Hantek products. In that budget tier I definitely tend to favor Uni-T. Not that they're premium quality either, but to Josh's point almost anything is better than Hantek, generally speaking. I was actually leaning towards the defacto DER-5000 but saw enough favorable reviews of the 1833C and it's improvements over the DER that I decided to go with it. No regrets as I said, I'm just not exactly in love with it.

What me  is each time to calibrate (open connection mode), specially the Cap as on startup 8pF off. As it do not gets saved even using last FW. After that 1pf SMD is possible to measure with the required fixture.

Anyway... for SMD parts a fixture is a must have and needs additional tweaking as cable and fixture. For more look on the good & ugly SMD fixture thread.

I think you'll find best practice with most LCR instruments is to calibrate before each use, especially a handheld unit that will be used in inconsistent locations or dynamic environments. As was mentioned, there's a lot of environmental influences at play in these measurements, especially with smaller values, so it's generally advisable to calibrate before every use anyway. I'm in the habit of doing so with my Hantek and it's not a problem. It's no different really than the practice of letting a device warmup to ensure best accuracy.

My test room is a small faraday cage. 
I joking, for me. But surely such is needed in certain testing environments, just like the various types of anechoic chambers.

Got an UT622E. Does all I need. Nice display.
Never had a LCR meter before, so I can't compare.

UT622A: 10 kHz max. No DCR
UT622C: 100 kHz max., No DCR
UT622E: 100 kHz max., DCR

The extra cost for the UT622E with DCR is probably not worth it.
So the UT622C would be the sweet spot here.

The high quality benchtop style are 5-10x the cost of the handheld units, perhaps for good reason, or perhaps the dollar-per-unit of accuracy & precision is just much higher on the better benchtop units. Finding a linear cost basis is almost unheard of these days. It's like double the accuracy & precision and pay 3x as much, etc.

I'd guess it's a combination of a more complicated design (no single chip solution), lower volume and different target market. But this has always been true. In the 1960s a differential voltmeter with 0.05% accuracy was also much more expensive than an analog Volt-Ohm-Meter with 1% accuracy.
