I bought this exact model for around 300 Canadian in 2019 (about 206 Euros). I was lucky to find a great deal for a brand new one shipped from China (the manual is in CH and EN). I was shocked about the features and the precision of measurements, its sturdiness and overall quality + feel. Still working strong. People, for its price point, if you're on budget and can find it around CAD $500, it's a no brainer, get it!
I used to install mobile solar power systems. I have a Fluke 289 I use to chart power consumption, charging, etc. I needed a second recording meter so acquired a Uni-T UT181A at a very attractive price. It served me for 6 years before I retired. I still have both meters but use the Uni-T UT181A as my bench meter because of the awesome display. I also utilize the dual temperature probe feature. I learned to hate the rechargeable battery, which demands a routine charging schedule to make sure you don’t get caught flat! Think about how you use your meter to see if you can tolerate that inconvenience. Otherwise, it’s a pleasure to use.
Shocking how much better the display of the Uni-T is compared to the Fluke and also how much faster it responds, especially in the trend/graph mode when zooming in and out. I wonder how long a full battery charge lasts when logging stuff throughout the night for instance. The Fluke devours batteries like there's no tomorrow. :)
Regarding battery life, the Uni-T also chews thru the battery, possibly that display uses a fair bit of power. And remember its a rechargeable battery, so if it goes flat you will need to recharge before you can use it again, the fluke you can replace the AA batteries (I use eneloops to avoid batt leakage). I havent directly compared my 181A with the 289 for battery life, but but I think the 181A has a slightly shorter run time. Though my main go to meter is a Bryman 869s or 786 usually, so I dont often use the 289 or 181A.
A most excellent 60,000 count multimeter. It would be a real game changer if it was a 100,000 count meter with the way test equipment is improving. 😎 Tony thanks for the great video. FYI: Amazon... $359.28 UNI-T True RMS Data Logging Multimeter UT181A display 60,000 Counts
Thanks, you guys are luckey, we pay 414,- on amazone in Euros, so that like 450 in US. Looks like to put some real attention to this meter making a nice product.
@@TonyAlbus I see. After reading the specification I guess it will be 32.768 kHz. 1 Hz resolution should be enough to adjust quartz clock generator. Thanks anyway. 🙂I need to correct my expectations. 1 Hz resolution is not sufficient to adjust quartz clocks. 1.13 Hz frequency change results in 3,0 seconds/day accuracy change for clocks with 32768 Hz generator.
I just got a new Aneng SZ20. I do like Uni-T and have a 161e+. It cost me about $100Cdn. But the Aneng only cost $55Cdn with free shipping. The 181 is literally ten times that! It does not have all the features of the UT181, but is 25,000 count and has a dual display. You should take a look at it. Aneng is not too bad. Thanks
I work in the automotive industry and am looking for a dvom that can graph sensor readings in real time. Like watching can bus communication. I want to be sure this allows for real time and can adjust scale from like 1v to 5v and adjust the time scale as well. Will this meter do that?
Hi Mike, that is where a multimeters and Oscilloscope are different. the multimeter is more for slower but longer logging, while you need something fast. If you have some money to spend have a look at the Fluke 123 or 124. if you have a budget. Owon made a nice one and Zotek is nice but for automotive maybe to fragile. i have at least 2 videos about the Owon DMM/Oscilloscope combi. HDS272 or the now newer now HDS2102
Thank you! yes i do. if i not had de fluke 287 i would buy it myself. read in the comments were people find small hick-ups i did not found in my test. you so make i good decision. but i would buy it.
Tony, you didn't check UT181A with LBA02A in resistance mode. I was trying to check my own and it shows strange values then. Other multimeter shows correct values. So my question is that maybe UT181A doesn't work properly with LBA02A in resistance mode.
Hi, this video was 1 year ago, i do not remember by heart, but if i did not mention it or you do not find it in the comments, i guess the usual 5 hours at least. but it could be longer.
interesting review. You showed that you can access the trending data through the software as a graph, but can you also get a list of the measured values and export those to a text format like a .csv file or so? So that further data processing is possible? And is this a meter that can be calibrated/adjusted? (is the calibration procedure accesable in the menu or at least known?) I think these are 2 requirement for this meter to be used professionally.
Nice review! I have the cheaper sibling UT161D and i'm very pleased with it for my skills of use. The instrument itself is very good, but as you say, the software leave a bit to wish for the 161D as well. Mine doesn't log internally, only on the PC but that's doesn't matter to me as i use it stationary only anyway. UNI-T makes quite good multimeters for an affordable price to us happy amateurs.
Hi @@TonyAlbus, thank you for a great channel with great content! I understand that it turns off when the battery is empty... 🙂What I meant was that when I do measurements over long times I prefer to have the power supply connected so that the battery discharge-time does not limit the length of my measurement. And if I understood it right the battery-charger of this device is using the input terminals so this rules out this device for very long time measurements.
Yes you are correct about the charger, i did understand your point, but i do not have one handheld in mind that can use an adapter to charge if i think of brymen or fluke... maybe the fluke 867, but not sure about the recording and memory. most other normaly priced multimeters just have non-rechargeable batteries. i saw in the comments that one viewer used it for 2 days before the battery died. 2 days is not bad. and thanks for the nice comment!
@@TonyAlbus Ah, ok. I was comparing with the Fluke 199C that I use for logging data sometimes. Ok, yes, 2 days is enough for most measurements. I suppose what I need is a type of data-logging device instead of multimeter. Thank you and have a nice afternoon. /Tomas
Its has been a while, i dont think i opened it, i do not remember. But you would think it is replaceble. To be sure you can ask your local dealer or UNI-T support.
@@GioJonnhyK it's a logging meter. It has to have endurance or it's pointless. I'm looking to measure voltages and currents over several days. And you can't use that thing while it's charging.
Hi. Does it still worth buying this multimeter UT 181A. I live in Netherlands and 2 weeks ago I bought UT61E+, but I don't like it. If 181A is much better, please let me know, because I am really confused
@@TonyAlbus From all the multimeters I've been watching for almost 1 month, I like these: Gossen Metrawatt M274S, Fluke 289, UT 181A, and Brymen 869s. All the others a saw and collected information - do not like
A very good meter. Agree with you in all points, but on the trend function it can't compare with Fluke. Use longer time logging (5-10min. on mains for ex.) and you will see that UNI-T can't zoom as Fluke do. It get out of the screen. Trend function on UNI-T is just informative (very poor developed).
The logging test difference base on a setting mistake. A Fluke recording settings sample rate settings is wrong. You set is 1 sample / 15 minute. This is the base of difference the number of samplings. In this case the fluke multimeter only registered an events, not a samples. Wrong setting, Wrong test, Wrong conclusion. Next time will better! :)
Hi there, can you please suggest a stationary multimeter under $500 (so-called "bench meters")? I mosty measure mV DC, mA DC, resistance, sometimes capacitance and sometimes MHz to see the tact frequency. My current device is +- ok, but I wonder maybe there's something better in terms of accuracy, I have Uni-T UT61E.
Hi, depends also on the digits you wand. If you want something good look for Agilent 34401A secondhand en ebay, if you want new. Siglent has nice SDM3000 Series. 4.5 5.5 and 6.5 Multimetrs..
Obviously this is intended to be used out in the field. I'm curious as to what are the applications of such a meter are. Where would you use one? Am asking because I'm very ignorant towards more complex electronic troubleshooting.

Yes they did a good job on this one.

Can it measure lower than one ohm ?
it does not have 4 wire, so i would not get too exceted about it for lower then 1 Ohm.
how could it not measure less that 1 ohm ?
I wonder if it is better inside than the ut171 which looks dangerous to use on any unsafe voltage.
Unsave is always dangerous. if you are planing to use 600+ Volts, maybe have a Fluke
If you use it electronics the UNI-T is a great meter.
