UNI-T UT33D+ CHEAP-O Multimeter Review & Teardown

[@srknycl9188]

I have this machine and it does the job. Thanks to your video I discovered again how to NCV

Very good reviews on cheap price multimeters

[@GhettoRanger01]

I've had the UT33A (auto ranging) for several years and I love it! It's small but it functions very well, it's well built and doesn't feel cheap, it's small enough to carry in my tote with my other tools, very handy. If you're looking for a good meter to keep in your car, home, or just a spare this little number fits the bill.

[@retrowikid]

The UT33C is a very good and affordable multimeter not much different to the UT33D shown in this video. I reviewed and used extensively an Uni-T UT33C. It is much better than other no-name designs. The only major shortcoming is that it has a rather small voltage range (no 1000V scale). I assume it is so because it would require that the multimeter have a proper ceramic fuse and other circuitry changes. Since about 2020, the model has been updated, as your video shows very well. It has a different screen, but it is less legible (larger dials but thinner). In some ways, it is not a step forward. It still uses the same 9V battery, which is a quite dated design today. I would have hoped the redesign to address shortcomings, but it is still a recommended product.

[@KeepOnTesting]

Yes would be nice to see them get away from the 9v habit as you mentioned. UNI-T always has some great offerings no matter what your price range.

I am thinking of getting ut33a+ should i go for A+ or B+ ?

[@yambo59]

I didnt see, did it do ok in just reading a regular diode-? Nice little pocket rig, four versions to pick from one is auto range and three manual with range variations, nice little base/budget general use meter for house or hobby.

[@KeepOnTesting]

Yes I've been neglecting basic diode output test, soon to remedy that.. ! All in all a nice CHEAP-O that's got a lot of great personality!!

[@yambo59]

Yes one of the best of the small meters, and one of the best working continuity ranges of ANY meter big or small -- way too many large or expensive meters have less than stellar continuity ranges. I see theres four versions of this model, and the A is an auto ranger but with other range differences, so choose your flavor folks-!

[@yambo59]

Just ordered the auto range version of this meter, this one looks pretty good, hoping the auto range with REL is even better-!

[@jesusmylordsaviorking3726]

I just got this in the mail. when I turn the dial it didnt do nothing. I suppose to install batteries.

[@KeepOnTesting]

Definitely, batteries help!

[@derektodd4126]

Yes Darren, resistance was futile @ £13-57.

[@yubinator7455]

I wonder if its sibling, UNI-T UT33A+, is better?

[@GhettoRanger01]

Yes

[@aryanrana4684]

Can we measure voltage of 1.5, 9 and 12 volts battries with this model? Otherwise the UT131B model has these three options to measure the voltage of batteries. The difference is the NCV.

[@KeepOnTesting]

You can measure battery voltage in dcv mode but no dedicated ranges.

[@derektodd4126]

Very surprising for the price point. Could be a handy little unit, especially for me with the 200M ohm range.

[@KeepOnTesting]

I think it's a charm, fast and frugal..well built a definate keeper! Derek, You know you want one 🤣👍

Hello friend, You can do a review of the szbj bm91b multimeter, It is a cheap multimeter but it says to be of good specifications, Thank you, Regards

[@KeepOnTesting]

Hi Brayan, your wish is my command, I've just ordered one from Ali, so it will take awhile but it's on the way!

[@gasca_mx]

@@KeepOnTesting Thank you, I'll wait for the awesome review, Thanks!

[@azilazwaashaari734]

Very great review. Like it so much

[@KeepOnTesting]

Thanks Azil !

[@derektodd4126]

Forgot to say Darren, I've had the 33D for maybe a couple of years on my bench. The backlight seems to stay on permanently, well I gave up after 5 minutes.

[@KeepOnTesting]

Wow that is an interesting side note , too bad they took away the indefinite backlight and replaced it with 45 second timeout...much prefer the former!!

[@nelsonsosa8797]

Darren, what value did you put the new fuse on, the same thing happened to me too.

[@camurgo]

Darren, do you know of any multimeter with 22000 counts cheaper than the Uni-T UT61E ? (It's 50 US dollars on eBay) I've been trying to find one cheaper with as much or more counts but failed so far.

[@KeepOnTesting]

As it stands I think that's the cheapest 22k count meter currently on the market.. I'm always on the hunt though, so if I find something cheaper I will definately let you know!

[@camurgo]

@@KeepOnTesting ok thanks!

[@KeepOnTesting]

@@camurgo No problem Leonardo 😃👍

[@bossomboss5828]

Ut33d but it doesn't gives diod figure while only good beeps for continuity so what reason could be plz.

[@KeepOnTesting]

I assume it has a fresh battery. Could be a shorted transistor..could be many things...how old is the multimeter? Try cleaning tbe pcb with Isopropryl Alcohol..including the range switch..that's always a good start..check for cold solder joints or anything else that appears abnormal...

[@bossomboss5828]

@@KeepOnTesting Thx a lot

[@watchmakerful]

Is it exactly the same as UT131D?

[@KeepOnTesting]

Yes..identical 😊

[@watchmakerful]

@@KeepOnTesting Can this device be calibrated? Today I found a used 131D on a flea market and it displays systematically high (~0.5%) on low voltage ranges. I don't see any obvious trimpots or other similar parts on its PCB, and its ADC is not 7106 compatible.

[@SUTH_33]

how NCV work? measurement for? test for? just ordered one ut33d+. maybe arrived soon ☑️ just different on a packing box compare your ut33d+. maybe my order is new version? maybe v3 💁 dunno 😅

Can i use ut33d+ to check the capacitor?

[@KeepOnTesting]

No, this dmm does not have a Capacitance range.

[@the-matrix-has-you]

Do you think it can measure 1uA to mA range correctly?

[@KeepOnTesting]

I doubt it...

[@the-matrix-has-you]

@@KeepOnTesting I thought so Thanks Darren. Do you know any cheap way to measure uA range without the need of Nordic Profile Kit II perhaps. I dont want to spend 100 dollars just to measure uA correctly but if there is no other cheaper way of doing it then I will spend that 100🙄

No capacitor support.

Please standardize your tests. Random tests cant be used to compare with other multimeters on your channel.

This review is over 5 years old. Have you looked at my latest reviews?

[@christophertadeo6120]

Oh it's the other one, back to a crappy 2 stars... 😀

[@frankbemelman7121]

Major design fault with this meter is the mA/uA current measurement using the same terminals as for all other measuremenst. Imagine accidently setting it to a mA/uA range, while still connected to a power supply. It will short your measurement probes. Current measurment should all be moved to the A terminal. But, then again, it is cheap but you have to be careful.
