Nice comparison review!!! It was nice to be able to see the FFT working in the PC software for the OWON! You were the only reviewer so far, to be able to get that to work!!! Thank you!!!!!!!!
Thank you Sir!.
So, to use the FFT function an active communication with the OWON is required?
Do you find a way to display some more details (db, frequencies) beside the curve?
I own a UT81-B from 2011….cost a lot of money that time, but I still use it today as in first day without no problem. I am very pleased for what can do.
Thank you for your feedback, great to know how they are after many years. Thanks!
Amazing work, thank you so much Tony, you've certainly put a lota effort into this.
Thank you Peter!
Thanks for sharing this! Appreciate your thoughts and time evaluating these units. Just ordered the OWON unit after watching this. Highly enjoyed your review. Keep it up!
Thank you, Glad it was a good help.
How are you doing with the owon scope , any feedback?
Thanks for doing this comparison and sharing your findings. Very helpful!
thank you
thanks a lot for a clear and goo review that heled me decide what oscilloscope I need. you looks like a sweet person :)
Thank you Sir, for the nice comment
I owned a UNI-T81B some years ago and although it was usable it had a hard time triggering on non-periodic signals. I "upgraded" to a UNI-T UTD1025 later which is a bit more comparable with the Owon and Hantek you are reviewing there although its bandwidth is less. It might not be a Fluke or Agilent but it is very capable and usable, at least for my purposes. Nice review, nice shack....keep up the good work Tony! Best wishes.
Thank you Mar, for the nice comment and sharing your meters. Although the Uni-T seemed basic, the software was good and it looks like a good reliable and strong device. Best Wishes
Top notch review Tony , keep up the good work 👌 , new subscriber
Thank you Biff, and welcome!
Nice job. I agree, I'm inclined to go towards the OWON for many of the same reasons. I do like the Uni t software. I wish we had more time to tinker with the OWON software. Again thanks for the video. Peace
Thank you for your comment!.. i kept the Owon, the rest i send back :)
This review is worthy ❤❤❤ thumbs up
Thank you Sir!
Good job. Other important items to compare are: Rechargeable vs normal batteries, batteries duration, backlite on/off, key beep on/off, buttons are preferred to selector on light handheld instruments, tips quality, insulation class. By the way, by vote here is Owon.
Thank you!.. the devices are send back (i keep the Own) , but Hantek and Owon both had beep on/off both display timers. i did have the feeling the Owon had longer battery life. the Hantek i needed to recharge, the Own kept working.
In the end my hds272s came out much better than the hantek , thanks it helped a lot in the comparison :)
Hello Janio, yes it did!.. i though they would be more the same, but in the end Owon really stood out.
Tony how nice your work, very professional... I loved it... Thanks for the material. Success my friend... Ass. POLILO - Sao Paulo - Brazil
gracias saludos
It's always impressing how good those cheap china Meters work. Thanks!
Hi Marcus, Welcome!.. I maybe would say 'some' of those Chinese are good. i also had a crappy cheap scope. but agree these were good. Thanks for your comment.
@@TonyAlbus Yes of course some are really crap (should stay in china!). But the others deliver performance for a price level which no one could believe it would be possible. Thus enabling also home user to get in touch with such devices.
Totaly agree!.
The Uni-T is an earlier generation scope. Its battery compartment is quite small, and has difficulty accommodating rechargeable AAs (which are frequently a bit larger than regular AAs). The Uni-T's screen is b/w only. Mine went bad prematurely, resulting in very inaccurate multimeter measurements.
Thank for this extra information, sorry to hear yours went bad
SUPER!
Thanks
Many complain about the sloppy solder work in OWON as compared to Hantek. It's hard to say how it may affect the durability of the former in the long run. There was also a video showing that ADC got pretty warm in the OWON though that was found in a later OWON 100MHz model. However the larger screen size of the OWON is so tempting...
Thanks for this extra information, interesting.
On UT81C the multimeter input capacitance is not automatic compensated you need to set relative mode to rest the 11 nf input capacitance. This will give an accurate result measuring capacitors.
Thank you for that extra information!
Did you try the single trigger mode in this review? I am interested in measuring the voltage variation in the ignition of a computer and I do not know if the owon will serve me
Hi Alan, that is a good question, no i did not... i have a big queue in my items, but i can pick it up in one of my QA videos, but that will take some time.
Does the Hantek oscilloscope function maintain calibration stability after say 10min of use, as the OWON, after 5-6min will begin to develop errors up to 15% when trying to measure signal voltage using the oscilloscope divisions scale, drifting far from where it should be. The DMM is fine, but scope wasn’t. You have to regularly recalibrate while using. Maybe some precision part in it is not temperature compensated?
That i did not notice during use, but i have not been using it, i usualy just use my Siglent. not sure i still have the Hantek, the Owon i have. maybe the Hantek was a borrow from Eleshop, i don't remeber.
Hey, great stuff. I bought a week ago a second-hand Hantek DSO8060 with a bigger screen and 70 Mhz. how is that one compared to these, similar or 8060 is significantly better?? thx man.
i Don;t have the DSO8060 here, but a quick look on internet: Real-Sample Rate 250MSa/s
Equivalent Sample Rate 50GSa/s .. that last part i dont get.. but it sounds like a lot. Also it is not clear to me if the 250MSa/s is shared over the 2 channels like on the little handhelds. if it is not, then it is better for sure.
Can you recommend some good budget oscilloscope for under 200 USD?
I mostly need it for microcontroller PWM signal analysis (on PC).
One of the viewers below is going for a hantek dso 2c10, if you compare with these 3 handhelds the sample rate of the Hantek is heigher which usualy should give you a better picture.
Hi Tony, congratulations on sharing your comments. In your opinion, which is the best Portable Oscilloscope?
I compared some specs:
- Battery consumption: Hantek
- Software: Hantek
- Maximum range: Owon
- Display: Owon
- Multimeter: Owon is more accurate? What are 20,000 counts?
I didn't see if it's possible to export data via csv file. Do you have any information about this?
I believe Owon Scope is a new project than Hantek Scope. Therefore, Owon needs more updates to remain more stable. How can I update Owon Scope?
I prefer to buy Owon Scope, I believe it's better.
Hello Carlos, i like the Owon best myself., i have it now.
1st DMM has more counts. (look at my video #213 if you like to know more about counts)
2nd the waves just look better
3rd Owon last longer on a battery, the battery is bigger
i also made a video about the software of the owon, if it was not here then maybe video #177 i am would almost be sure that software can export csv
@@TonyAlbus thanks man
Hi sir Tony,
First thing first !.... *wishing you all the best for ALL BEST in 2022*
One cuestion, are these multimeters compatible for the automotive industry-diagnostics?
Thanks for your time,in showing the compatibility and reliability of the 3 models.
Have a nice day.
Best regards.
Thank you Sir, all the best to you too. I am not sure what makes an DMM an automotive DMM, is it the protective case, is it temprature senor?? i am not sure.. but i think i have read that the OWON is used for automotive.
@@TonyAlbus
Ok Sir thank you very much.
Thanks for the fast reply and for the info....*now I know it's reliable for automotive diagnostic services.
I appreciated so much the different in specs. of the 3 models you choose.
Thanks for your time,illustrations,specs and extra informations.
Best regards.
@@gladmarchatlein8164 Thank you!
this has convinced me to buy both of them as"mr hadden" would say why have one were for the price of two you can have two, , ,
LOL... yes indeed :)
Hi Tony, congratulations on the video. I have a UT81C multimeter which I am very happy with but I would like to ask you a question. I tried to make output voltage measurements from a line interactive UPS, in battery mode I measured approximately 180 V with an approximate sinusoidal waveform. I wanted to ask you why I can't measure a value of around 230V. Is it by any chance that this oscilloscope multimeter is not TrueRMS?? Thank you so much for your attention and congratulations on your channel.
Thank you! how are you doing the mesuring? in DMM mode or oschiloscope mode. in scope mode you can see the peak-peak. and then calculate your value.. TrueRMS only works differen with squarewave in DMM mode.. with sine there should be no difference between TrueRMS or normal
@@TonyAlbus I tried to make the measurement with the oscilloscope mode, I can perfectly visualize the approximate sinusoid with a voltage value of 180V. Tomorrow I will try again to measure voltage using only the digital multimeter function without an oscilloscope. I want to see if there is a difference or not. I'll let you know updates. Real compliments for your channel. I wish you a good afternoon.
@@mauriziodimichele4589 Thank you ! greeting!
I would buy one of these if it had: The large 3.5" color screen of OWON and the large clear font of digital readouts of UT81C. Hantek's small 2.8" screen is pain ro read and UNI-T's specs are now below the modern standard although it's slow update rate and sluggish LCD response downgrade it as well.
Yes for these prices it will not be perfect.
Hi! I am looking to buy an oscilloscope. My needs are not too high. i am considering between owon hds272 and hantek dso 2c10. The price difference between these 2 products is not much, hantek is more than owon ~ 20usd. In your opinion, which one is better to choose? I use it for simple crafting
The sample rate and analog bandwidth of the Hantek is higher that is a good thing. if you don't need it to be portable, i think that is a nice choice.
@@TonyAlbus thank you !
Good
Thank you!
Would the Hanteck CC 65 Current probe work with the Owon? Also have you tried to run the hantek software with the owon?
Thank you... i did not try the software of the other brand, just Owon with Owon as it was designed like that. Maybe i can try that once. The current probe i do not have.
@@TonyAlbus darn okay thanks. I dont see why the hanteck current probe would not work with the Owon
On Owon HSD272S we see a wider beam.
As I understand it, this is something like drawing in all the ray distortions. Therefore, it seems that it is quieter, there is no beam jitter, like on the Hantek 2D72.
Something similar can be seen on the test video DSO1511E : ruclips.net/video/_cvULRRsrtw/видео.html
Thanks for the link
What is that "click" sound when you start OWON? Seems like some internal relay. Thank you
Yes i would think also, maybe something for auto-ranging.
@@TonyAlbus well i hope it will withstand big amount of startups, because i am seriously thinking about buying this meter, thanks to You :)
Hi, got the UNI T UT81C, inside the multi meter has only a small area for shielding so it's prone for the AC interference, i plan to use aluminum tape to widen the aluminum shielding, do you think that it would be okay and would work?
thanks.
john from the philippines
aluminum foil tape i mean
Hi John, if you have no problem now, i would not change anything. if you put the tape wrongly and you work on high voltage, it could create maybe a short spark bridge.
@@TonyAlbus thanks for the advice
Q: From beginner.
Can I measure this direvtly sine of 230V AC ?
Yes it can! 1000 VDC , 750 AC
Prefer the owon, though I think for multimeter settings the rotary switch is more easy.
Btw: your windows desktop is ordered like mine with the icons in “islands” and only using left, top and right area. :)
Hi Marnix, Yes the Owon is my favorit too, it is also added to my collection :)) The PC, yes i like my desktop sort of clean and group it, i don't searching for stuff it needs to be where i know it is...
I have Scopemeter Voltcraft 707,
I Cant found any data of this Scop,
You help me for bandwidh freq?
Hi, i checked some of my sources, but i also don't see anything other then a few pictures.
Does the Uni-T 81B capable of logging?
Hi, the 81C can do logging, the 81B i have not here. i can not tell you.
Eu tive um hantetek ,que terminei me livrando dele,era lento e a tensão de diodo não chegava a 3 voltes.
Tambem tive um uni-t ,decepção total ,muito lento
Thanks you for sharing that..yes it are entry-lever scopes, but very useful for basic tasks or automotive.
Was 7.5V really that far out on the Owon???
It should be 7.449. You mis-wrote it. @ time 10:22.
I meant 7.499! Anyone can makes misteaks.
It was allmost spot-on :)
Hi Tony!
It was some pleasant to me to watch your video. Many thanks for job you do!
But I was surprised when you was comparing the Volt and milliAmp mode on both devices. I would connect all instruments in parallel to check the voltage and to connect them in series to compare the current. I reckon this way is more obvious than you do.
30:45 - To recover this moire line you need to disable one off two input. This give a line more fine. Please refer this video ruclips.net/video/CF3zBHMhQlM/видео.html
Thanks, nice video!
nice info... for $700 i want bnc isolated inputs for motor drives and a $25 hard plastic storage case included... thanks a lot.... 😉
Welcome!
Owon HDS 272s has software glitches, it suddenly stopped measuring anything in dmm mode , checked everything resetting made it work, but its doing same thing intermittently, I opened it to check if anything is damaged, but nothing happened in the inside, but the quality is worst in the internals, looks like a prototype, with hand soldered capacitors and flux everywhere, I also had hantek 2d72 its internals as well as body is high quality, except display and few multimeter specs there is no gain with owon ,quality is worst on owon, hantek works well for it's specs rather than this gimmicky owon.bought it with a lot of hopes, wait for few more board revisions because internals are worst in owon.
Thank you for sharing your personal experiance.!
was thinking of selling my 2D72 for the owon. I had my 2D72 for almost two years its been reliable. With the recent Nov 2021 firmware update its even better.
I am too lazy to watch all of them. So which one is better....
owon
My Dream Device, I Will never Own Such Device ;( SO SAD:( !
Maybe one time sur!.
Como faz pra medir VRms no Hantek ?
The Hantek does not mention this is the manual, but the Owon is True RMS according to their specs.
@@TonyAlbus há uma maneira de atualizar o Hantek pra ele medir VRms, pode gravar um vídeo passo a passo ?
@@nasasoundbr3737 I don't have the Hantek anymore, but maybe the Hantek can do RMS, i just did not find it in the manual, maybe you can find it in the website.
try to contact the support of Hantek, maybe they can help you.
I realize that Hantek's DMM is not TRMS, what about OWON? It definitely uses another DMM schematics.
Hello.. Yes the Owon says: 20.000 Counts true RMS .. btw, if you have the schematics, can you please share with me?
@@TonyAlbus No, i don't have it. But usually these handheld combo DMM-scopes have separate DMM daughterboard (at least, my CEM DT--9989 and Hantek DSO1202B have) which are rather similar to pure DMMs (CEM DT-9989 has the same DMM as DT-9979) I guess your Owon part should be similar to Owon B-35t DMM. My Hantek DSO-1202B does not specify if DMM is TRMS, and there is contradicting data in the Internet. Big thanks for your comparison!
The Hantek is not fused, so if the OWON is a clone then its a better clone.
Agree, i did not even spot the FUSED and UNFUSED, thanks, i like the bigger screen and software UI is just more easy, also the waves are more stable..
@@TonyAlbus Yep. I ordered one myself, just waiting for delivery.
great! hope it arrives soon, i am thinking of that too :)…. there are borrowed.
Some other comparisons, Capacitance: Hantek 100uF vs 2mF Owon; Resistance: Hantek 40MOhm vs 100MOhm Owon; Diode: Hantek max 1V vs 2V Owon.
Hantek does not have a fuse, so it is easy to damage if the wrong scale is plugged in.
I choose Owon
@@dhphuckts Thanks! .. that is a nice addition
