How can I check if factory coils are ni200 or titanium?

[WiSK]

I recently purchased Coilart CTOCC ni200 0.1ohm coils. But when I received them, they were 0.2ohm and they don't vape properly. At my standard 240C/40W setting for nickel I'm getting either poor weak cloud, or burnt taste. So I asked my money back, and now there is radio silence from Coilart

But still, I'm curious how I can find out exactly which type of wire is in there. I have a DNA200 device so I can maybe use Escribe. Anyone tips on how to test these coils easily?

Cannot you see the type coil printed on the coil housing itself? Most premade coils are marked that way...

Yes, of course it says Ni200 0.1ohm on the housing and on the packet, and that's what I ordered from the website. But as I said, it reads 0.2ohm (on DNA200, VTC-mini and on TC60W) and it doesn't seem to behave like nickel. I have experience with plenty of other ni200 factory coils: SSOCC, Crown, Cyclone, Goliathv2, Wismec Amor and these ones just vape wrong.

So I think it's a production mistake and I'd like to know how to discover what material the coil is actually made from.

I guess you could have a metallurgist analyze the coil wire. The DNA technology has no way that I'm aware of to determine what the coil wire is made of other than distinguishing between Kanthal (non TP wire) and TP wire. I guess you could ask the manufacturer to let you send the coils to them if you think they were packaged wrong. Many premade coils don't ohm out at exactly what they are rated at and atomizers also can have internal resistance too.

You have a dna mod so go into the analyzer escribe, fire the coil with the ni200 and then the titanium settings (low watts so you don't burn the coil), and check the results. You should be able to see if it behaves like it should in either ni200 or titanium mode.

I already asked Coilart but they didn't know. If I take the wire out of the coil, then I can probably figure it myself by looking at volume v mass and/or volume v resistance. But I was hoping to figure it without destroying the coil head. The resistance measured is fairly consistant between devices, and I tried a fresh coil out of another packet. It's unlikely 2 coils would be 200% of their rated design. Again, that's why I think it's a production error like: wrong material, wrong number of wraps, missing parallel wire.

What specifically am I looking for? Obviously with the nickel setting the device will trigger temp protection for 250C at around 0.476 ohms, while in the titanium setting the device will temp protect at around 0.365 ohms. How can I further analyse the other readings shown in Escribe?

Maybe in Device Monitor you could analyze Cold Ohms and Live Ohm's while firing and compare it to the material's TFR linear graph...

I think how much the resistance changes with temperature would be your best bet. You can use Steam-engine.org to compare how the materials should behave.

Thanks guys but unfortunately both suggestions would need an independent measurement of actual temperature. The device can't tell me the actual temperature, because it is only a calculation based on TCR setting. And it's the TCR setting which is in question.

You'll in any case see how the resistance changes. You don't need anything exact here, simply a rough view. Ni200 will have much more of an increase than titanium.

it's most likely an NI200coil. you're just not putting enough power into the coil or your set temp is too low. for a NI200 coil to be at .2 ohms there must be alot of the wire, i.e. lots of coil mass or your device is reading the resistance off. try 75 watts at the same temp (240C) and see if it makes a difference, play around with your watt and temp settings. just because one setting worked for one coil doesn't mean it'll work for another, even of the same material.

Well then for another easy way to test them..... set up your device for normal Ni200 and vape it.... Then set up the device for Titanium and vape it..... Which one vapes like it should....???? I assume you have vaped Titanium before.... Good luck....

Also you could take a multi-meter and take an ohm's reading from just the coil head with it not installed into the atty.... maybe it will read 0.10 ohms...

I don't like it on either setting. But yes, the ni200 setting seems "like it should".

For comparison, I dug out an SSOCC 0.15 ohm coil and found a good setting (250C starting at 40W). Device reads 0.191 ohms so indeed there's quite some internal resistance in the device and atty.

With the CoilArt coil reading 0.232 ohms on ni200 setting, we see similar behaviour.

For further comparison, a Crown ni200 coil, nominally 0.15 ohm reading 0.171 ohm (but it needed 240C and 60W preheat for a nice vape)

So I guess it is indeed ni200 just higher resistance than rated and not a nice vape That's a shame because the review I read (ostensibly of a 0.1 ohm ni200 coil) was favourable; that's why I ordered these.

Thanks for your suggestions guys

A TI coil ran in NI mode will be 100-150F hotter than the set point.
