Review - UNI-T UT81B Scope / Meter

[jleaman]

For Christmas my Fiance asked me what i wanted, I asked her to get me a Uni-T Scope hand held meter, It's only 10mhz but that is all i need for audio.

I got the meter a few days ago and have been playing with it and the software, for 190$ im pretty impressed, it's not heavy at all, takes 4 AA batteries, and has a very bright and crisp clean display that is really easy to read.

the unit was purchased from mib-instrument's.


UNI-T UT81B 40MSa/s Oscilloscope digital multimeter

I can post pictures if people want to see better pictures.




Soon i will be purchasing a Function gen & 2 more desktop meter's ( witch i want )

This has been my second purchase from this good company.

Hi jleaman,
I wonder if you can tell me what sort of data is available via the USB connection on this device?
Can you grab scope waveforms? Or just multimeter readings?
What sort of PC software comes with it to support the USB interface?
Thanks

Got my ut-81b yesterday and am well pleased with it; it's a pity there was no 'scope probe lead but for the price (£125 inclusive) I suppose it won't kill me to spend a few more £'s on a 10 MHz probe.

A very serious omission, though, is that of a probe compensation adjustment signal output; there must be a suitable rectangular wave signal available within the 'scope's circuits and a simple buffer would add a very few pennies to the cost?

That whinge apart it's great value; providing as it does the functions of a portable 'scope cum multimeter and those of a bench 'scope when tethered to a computer - sadly only for Windows users; those of us using Linux or O S X, will have to downgrade to an inferior O S!

Hey can any of you guys crack it open and take a few pictures? Or is that not possible. I'd like to see some example of its build quality.

[REDBEEMER43]

I opened mine up the day it arrived and it looked to be well built with decent quality components on a good-looking PCB - only time and use will tell tho'!!

I'll take some pics tomorrow or the day after (busy, busy!) and if I can fathom out how to attach/link them I'll gladly do so.

Thanks. I've seens a wide variety of build quality from Uni-T. From absolutely terrible to golden Fluke standards. I'm hoping this one will be more of the latter than the first.

Thanks.

[REDBEEMER43]

Mine looks up to Fluke standards; certainly nothing like some I've seen that look as tho' component placement was by a shotgun at a range of 4 feet!

I've got a couple of pics but do not know how to link them to this site

[TheLaw117]

Oh I'll tell you how.

Thanks for the help with the attachments

I hope they help you to decide to buy one.

Thank you for the great shots.

They have some nice tatalums on there. Only thing I might be concerned with is its protection circuit which I can't quite see from the pictures. I do see a single glass fuse. Usually I'd prefer to see atleast a ceramic, but I guess I'm being picky.
