Boge LR Cartos - Resistance tested +.5 above stated ohms?

[lot_49]

I started vaping a few months ago and have been using Boge cartos on my eGo batts fairly consistently. I have a few tanks which I've been using with Smoktech Dual-Coil 1.5ohm cartos and, recently, the SmokTech 1.7ohm "Resurrectors."

I alternate between the SR and LR Boge cartos depending on the juice. It was only recently, however, that I put two and two together and realized that Equus Innova 3320 multimeter I'd purchased for my car earlier this year could also be used to test my e-cig equipment! The most helpful tutorial I was able to locate is GeekGirlVaper's video on YouTube.

Background aside, all of the literature I've seen on the Boge cartos has indicated that the LR cartos should measure at ~2.0Ω. I just tested a few LR cartos, however - brand new, if that makes any difference - and my multimeter is indicating a resistance of 2.6-2.7Ω. This seems to be a pretty substantial deviation from the advertised resistance of the LR cartos; has anyone else experienced this?

I also noticed that this batch doesn't contain the typically longer bottom condoms with the skinny little removable rubber stopper on the threaded end - rather, the threaded end comes protected with a duplicate of the shorter condom on the mouthpiece. Could this be a newer (or older) series of the Boge cartos? Are they even the Boge cartos, or some cheaper, higher-resistance knockoffs? I bought this batch of cartos from a vendor I'd not used before, but they have a great reputation - furthermore, the Smoktech dual-coil 1.5Ω cartos I'd ordered all test within +/-0.1Ω of their stated resistance, as do the 1.7Ω Resurrectors I'd ordered from the same vendor.

Has anyone experienced this? Might anyone be able to shed some light?...or figure out what I'm doing wrong, for that matter?

Did you subtract the resistance of your multimeter's leads. Puts the black and red leads together and check the resistance. Subtract that number from the reading.

I just checked a few boges that I have on me right now. I used my provari to check them.

All of them are LR. Some of these especially my black ones have been cleaned (boiled them). Not sure it the resistance can degrade over time.

Black:
2.6
2.2
2.2
2.3

Stainless:
2.4
2.5
2.4
2.3
2.4

The one with 2.6 I have been using today. I noticed it was a little low on the vapor. Lucky for me I can just adjust my provari's voltage to fix this.

I did subtract the resistance from my leads (I mean, you could say that I did - the resistance on the leads is nonexistent / 0.00). Occasionally it'll jump up to .1 for half a second and then it's back down to zero for another five. I'll have to track down some of my older, gunked-up cartos to give those a test and see what happens...

I gotta say, though; the first big thing that threw me off was the lack of the standard condoms I see on these. Besides having the same size piece on either end with no removable rubber stopper, the condoms fit very loosely over the cartos and even fall off if I wiggle them around a bit. I'm using the stainless ones, so they don't have the added thickness of the black ones...but even the stainless ones I've used prior to this order have always taken a bit of picking and shimmying to remove the condoms; nothing has ever slid straight off like with these new ones. The box looks identical to every other one I've seen...I'll see if i can't get a picture once I get home.
