4 new luxmeters compared (sept 2018)

Will you also test the TA8134?
Maybe you could make a picture from both TA8133 side by side with open sensor So its easy to see that they are not the same internaly. Would be interesting to contact Tasi and get a answere if the crappy one is the new or old version. If they answere at all! But the picture would help to bridge the language barrier.
Not interested in buying one if i have a 50% chance to get a scrappy Meter. But i am willing to ask my way through their support :smiling_imp:

I’m not really on an active mission improving the manufacturers. If my information gets so widespread (not likely, even here these luxmeter posts do not get many reads :partying_face: ) that customers and manufacturers take notice and make better stuff, I will be very happy, but I’m not going to contact them about them.

Atm, I’m not planning more luxmeter tests, that said I do not expect extreme different performance of the TA8134, mostly a different housing I guess.

Thanks for this valuable info! The Extech looks good!

I have a TA8133 from an other seller waiting for the end of the hollydays in some chinese warehouse ;-)

Will tell you what i find when it'll be here. (fingers crossed)

I only wanted to ask them what i get when i order from them. Is the crappy one the old version and they upgraded to the better design. Or have they rebuild the good ones and now are selling a version nowbody wants.
I am not trying to change/help/work with them. I only would like to know if its woth to spend my money. So i would ask. But language is a problem contacting Chinese companys. A picture often says more than 1000 words. Here you are showing the TA8132/33. Is it the same with the crappy TA8133 and the good one? If yes this picture would be good enough!

I just checked the sensor of my latest (“good”) 8133 and it looks almost like the “good” 8132, but the rim of the sensor is different, so yet a different version, although in details. Would this different sensor be related to the better resolution at low light? Nah, that would sound like reason, they probably use whatever component is available at the time of production, sometimes this one, sometimes another. :smiley:

Thanks djozz! Mail is out and i will post the result when/if i get a answere!

Update from TASI:
They told me that the version with the bad sensor is the old version. And they are not selling this version anymore (they wanted to know when and from which shop the old ones was bought).

They also said:
You can buy directly from us, we are the manufacturer, we can assure you our quality. Please don’t worry about the sensor we will send you our updated new product (USD17/PC).

So it seems the new Meters should be with the good Sensor ( But aslong you are not buying directly from TASI you can not be sure to get the new one).

That is a surprising outcome to me, in principle encouraging but time will tell if that is indeed the case.

Thanks Docc for contacting Tasi, even if it is not true what they say it helps if manufacturers know that their customers notice and care about the build quality of their products, which is not obvious in case of luxmeters.

I also hope that it is the truth! I not only asked which one i get i also linked the test :smiley: so they know it is not only one person asking. And that many more people will be aware of their answers.
I asked how much shipping will cost (and ~shipping costs for the bigger countries). If it is not to much (compared to buying on Aliexpress) i will order one directly from TASI. Then we will see which one they deliver. I also asked if they sell directly on Aliexpress (could not find them on Ali).

As I predicted, the bad one was probably an older lower quality version.
Let’s see if buying directly from them gives you the new one.
Good thing it’s easy to tell which is which.
Thanks for the info :slight_smile:

Ok i was expecting to pay a bit more than on Aliexpress. But a total price of 47$ inkl shipping is a little bit to much for my taste (cheapest price on Aliexpress is less than 19$ inkl. shipping.
I think we will have to wait and see what we will get from Aliexpress when the Sellers old stock is sold and new ones are orderd from Tasi.
@ Djozz
Is there any difference in labeling on the two 8133? Something we can ask the Seller before we order (except the red cap at the top)?

I received my TA8133 ordered from BZG Electronics Co,.Ltd this morning

The top of the case doesn't have the red part and guess what ...

When comparing results from various light in my cheap integrating sphere with a calibrated Minolta T-10A, the TA8133 seem to be 30% to 50% off :-( :-(

^ :person_facepalming:
I’m sorry to hear that.

Real sorry Kame Sennin.
But you saved me. I asked BZG Electronics yesterday and they answered that they have the one with the red top in stock.
Now i ordered from frank hu’s store and hope to get the right one!

I have a 6133 on the way from Frank Hu that just left China. Will report back when it arrives.

I think i have bad news. This morning i was contacted by frank hu’s store (some payment issues). I should cancle and please reorder (happend before on Ali). I took the chance to ask him about the 8133. He confirmed our worst fears. Every new delivered Tasi meter in 2018 is the one with black top. And he also has only the new (black ones).

So this makes me think about the answere i got from Tasi directly! (was it a straight lie?)

Are you sure he knows what you’re talking about?
Both of them have a black top, the difference is that the better one has a small red piece in the middle of the black top.
Maybe he misunderstood you?

I send him two pictures. One with the red top and one with the black. He said the black one is new one.
