DSE901 atomizers photo close up view and info

[robw]

This is not a review, and it gets technical, skip to the end if you want the bottom line.

I was attempting to solve a vapor volume problem for my wife and after doing some experiments I came across some interesting info.

I have taken this photo of the atomizers from 3 suppliers. They are labeled.
The atomizer from the screwdriver and the one from puresmoker are identical.
They both have a bridge that sits 9.4mm from the rim and spans the width of the hole to the inner pot all the way to the body wall.

The Litecigusa atomizer sits 6mm from the rim and spans only as wide as the inner opening of the pot. The inner pot opening is also about .5mm smaller in diameter.

Ok so what does all this mean.
My experiments were done to determine which 901 atomizer performs better.
Here are the results

• The battery supplied with the screwdrive fully charged reads 4.02 volts
• The dse901 battery, supplied by Puresmoker supplied 4.17 volts

The Screw driver performs best on the included atomizer, or the atomizer supplied by puresmoker. It does not have enough voltage for the litecigusa atomizer

The 901 atomizer from Litecigusa performs best on the mini battery from puresmoker.

The atomizers from the screwdriver and puresmoker do not perform as well on the dse901 battery as the atomizer from Litecigusa does.


Here are the reasons why.

The atomizer from Litecigusa needs the higher voltage than that of the 4.02 volts coming from the screwdriver battery. When it gets 4.2 volts its narrow bridge allows the heat to be concentrated to a smaller area thus producing hotter and higher volume vapor. It is also 3mm close to the mouth peice which allows for deeper cartridge compression as well as less travel distance to your mouth which reduces heat loss.

The atomizers from screwdriver and pursmoker have a wider bridge which spreads the voltage out to much causing lower heat thus lower volume of vapor.

Does this effect the quality of any of the products?
No, they all still work and work as described.

The best performer for heat and volume though would be the litecigusa atomizer on the puresmoker battery. I have to assume the battery litecigusa sells is the same voltage output.

In order for the screwdriver to use the thinner bridged atomizer from litecigusa, it will need to produce at least .2 higher voltage to properly heat the atomizer. Increasing the voltage to the wider bridge atomizers do not make them perform better as test on the dse901 battery. The battery supplied with the screwdriver is rated at 3.6 volts. I purchased a few different batteries from dealextreme to experiment with. When they arrive I will update this.

So the bottom line.
DSE901 I prefer the atomizer with the narrower bridge.

screwdriver, it works fine on the wider bridge, however if you can find a higher output battery it will perform even better on the narrow bridge atomizer. Giving you a longer use time and hot large vapor.

Im going to experiment with pinching the bridge on the screwdriver and pursmoker atomizer to see if the perfomance is based on the bridge shape alone.

Higher voltage = quicker discharge/per charge. The bridge is simply a wick, and not the place where liquid turns to vapor. Its only goal in life is to transfer liquid. Same reason you can still smoke an atomizer without the wick but can't use cartridges ... If you drip 2 drops on a hot wick, you will see it absorb at the same rate of speed as a completely cold wick ...

Explain how a widening of a wire wool wick would spread out the voltage when voltage itself is centered at the pot?

I like your testing though ... You should try averaging it out over 3-4 atomizers per supplier to find a median. I would also like to see what the circumference of the wick itself is ....

EDIT: Also, what are the Serial #'s on the batteries (minus the screwdriver) I know what mine would be, what are LiteCig's ???

Interesting, the bridge shapes may still affect vapor though.
The distance from the inner pot to the wick may have some play here. I wish I could get inside there and do a high speed video of it.

I ran the volt meter on the bridge and there was only .05 volts on activation.

I'll have to recant my remark about the bridge heating up. The heat I noticed appears to be only a transfer from the core.

What effect do you think having the bridge farther away from the core has if any?

[CaSHMeRe]

robw ... I am loving your research though This is what we need !!!!!

The only factor that would come in to play as far as distance of wick to pot would be the transfer rate of the liquid itself. Did you ever do an experiment in grade school, with colored water and celery? The longer the stock, the longer it took the celery to absorb ...

What may also be another factor is the density of the wick itself as well ... not even sure how you would test something like that .... Can you measure circumference of the wick? Would be interesting to see the heating element itself (coil and pot) and see if there is a size difference.

[robw]

I think I know what it is, it is the .5mm smaller size on the pot. If the pot is smaller then it can heat up faster due to smaller surface area.
Of course I can't confirm that until I take all the atomizers apart.
Maybe I am just to fricken anal about this stuff.

[robw]

Ya , Ill do that for you. I have one dead one I can mutilate. As soon as another goes Ill compare them.

Im also going to experiment with higher voltage. Id like to know the burn out level.

[CaSHMeRe]

perhaps, but if the pot was smaller, it also can't hold as much liquid, thus resulting in lower vapor output. at least that is what I would think. I'm also not even sure if .5mm will have much of a different on anything. If it were a 1-2mm difference and you could honestly see a difference then there may be some truth to it, but .5mm is awfully small.

did you see my other questions though, on circumference of the wick and density?

[robw]

Yeah, I can test that by just measuring the temperature of each atomizer. That should have been part of the first test, but my wife was waiting for her cig back.
