Atty's resistance or "Ohms"

[nephillim]

Has anyone tried determining if the resistance on an atomizer changes when its nearing its end of life or just too dirty? This might be able to help us understand more about them.
I would test this theory, but I just started vaping and haven't *knocks on wood* lost any atty's yet.

Just a thought..

From my experience with the 901, the atomizers don't die gradually. They vape good one minute and are cold the next. I usually get around 3 ohms with a good atty and 1000++ ohms with a dead one. Dissection of the decedent usually shows a broken wire as the cause of death. The fact that a dead atty is still showing a high ohm reading is likely due to the wet gunk that adheres to the coil wires.

Zero ohms, atty is dead; 3.5ish ohms, atty is functioning properly; high ohm reading, the atty is FTD (fixin' to die).

Whenever I have a doubt, I check them. Till now, I did never observe any other reading, than either the original 3.5 to 3.7 ohms, or none.

Not all attys have the same default resistance. Some ohm meters have a specific false reading of about up to 0.5 ohms. Check it first, by holding the two pins together.

I just checked mine, I get 3.5 ohms on my 901 atomizer and I've been using it for almost a month now.

 

[smokinbob]

also, as the post above states, I get 0.4 ohms as a false reading.

one of my 801 janty reads 43 Ohms now, a few days ago it stopped working with 55 Ohm.

i would check whats up with that piece, but it will be changed... at least i hope.

I throw out my 801 atomizers when they read above 20 ohms. At that point, it is too hard to get them to produce any decent amount of vapor.

I get a resistance of 3.2-3.3 ohms from a new atty (RN4081).

Mathematically speaking a dead atty would have infinite resistance, according to Ohms Law. just an observation.

True, but in the case of an atty the coil is often encased in a build up of gunk that allows for some connectivity even though the wire is broken although never 0 Ohms. From my experience with the 901, a dead atty's resistance is often over 1000 Ohms, but the needle is still on the scale.

send me your dead atty's, don't throw them away! I'm working my .... off trying to find the perfect atty cleaning fluid but I'm out of dirty atty's to test/clean with....I've cleaned all mine and recovered all !! pm me for my addy....

Before you throw these away, I will take a couple. I am working on a way to rebuild these,,,,, or even make a better atty, following some information on this forum.

A cleaner would be nice.

But even nicer would be a heavy duty atty that can take the heat without burning up at the higher voltages.....

In my experience with M401 attys, 3-3.5 means a good atty. The other day I was using a good one and it started producing less vapor. It's at 7.5 now. Why does that happen suddenly?
