Testing for Great Atomizers

[Brian S]

One thing I have noticed is the inconsistency of atomizers. I buy 801s and about 1 out of 3 is a great atomizer. The others are just wimpy. On a lark, I decided to break out my multitester and see how many ohms the atomizers were. Great atomizers register 3.5 ohms. My wimpy atomizer registered 9.3 ohms. Because of the greater resistance, the wimpy atomizer just wasn't getting as hot as less current flows through it. Now I plan to test my atomizers when I receive them and send back the ones that don't make the cut as I am tired of throughing them away.

You only found one that was over 5 ohms (a reasonable cut-off point)?

Since the length of coil wire would be almost exactly the same in each case, wonder how this could happen. Bad connections are not in the 5 ohm range; generally would be hundreds of ohms and more.

Sending back attys with a resistance over 5 ohms (testable) seems a good idea; you can say exactly why they are deficient.

5 ohms may be a reasonable cutoff point. Only tested three so far and two were at 3.5 ohms. I have about 10 I need to test later today. The thing about the 9 ohm one was it had wimpy vaper and a much harder draw. Not very satisfying at all. Also, the 9 ohm atomizer didn't wick the juice from the atomizer as well as the 3.5 ohm ones.

Could be a lot of things causing the difference, a longer coil wire. A coil wire with a different diameter, the way the coil wire is connected. The ones I tested were from the same supplier. I'll know more later today.

Hey...

I'm a EE and ohms are one of my turn ons

How can I help define the characteristics of a good atomizer?

FYI Even though DSE901 atomizers and JOYE 510 atomizers are of similar design, it seems to me that the JOYE 510 atomizers are performing better than those for the DSE901. I have attributed this to the thicker 510 providing more air around the heating element. What do you think?

The 510's have strands of some type of wicking material attached to the the underside of the metal wick, do 901's have it? I never noticed it on a 901.

I build guitar amps as a hobby so I guess I'm an EE type too. Home_Page

It seems that two factors are more important when producing vapor. The temperature of the atomizer and the voltage supplied. Given a resistance, the temperature should increase when a higher voltage is suppled. Lower the resistance, and the higher current flowing should produce a hotter atomizer. Check the resistance on your different atomizers. If it is the same then the additional air may be a factor.

This is really interesting

Moving away from best vapor for a minute...

I would think that if the heat is not properly dissipated away from the atomizer, it would significantly shorten the life of the atomizer. Maybe the best combo would be for the atomizer to get really hot for a very short period of time, then quickly cool.

Which brings my next question. Which would be a better housing around an atomizer? Good conductor (metal) or good insulator (non-metal)?

There is definately a fair amount of inconsistancy in atomizers. I fired up a new one from my last Ruyan order. It was weak from the start and it flooded very easily. Never had a flooding problem with any atomizer before this one. Been using it for just over a week. It works, but just not as aggressively as I would like. So I blew it out today and got a few drops out of it, then did a about a 10 second heat cycle on it. Let it cool and did another... then it gave up.... dead.

So I grabbed another out of the same order and - oh glorious vapor! Like a freight train! Huge throat hit, pure endulgence!

Hopefully as these become more mainstream, the production quality will follow along and this won't be such an issue.

I'm referring to 901 atty's run with an 18650.

The problem is by the time you figure out which one is good the warranty is out. Mine may sit for months before I actually use it. It would be nice to know if one is up to snuff immediatly and ship it back.

My workaround for the 901 is to buy five atomizers at a time and toss out the ones that fail. That shows how much I prefer the 901 over other cheap ecigs I've tried.

This is a bit off topic, and I suppose you guys get your parts directly from China, but does any US distributor sell 901 atomizers in packs of five like Totally Wicked? My wife and I don't like the devil logo and I haven't been able to remove the darn thing.
