Ohm meter/atomizer?

[RavenManiac]

My 24 year old college student just started vaping to get off the 1/2 pack of cigarettes he's smoking each day.

As a concerned parent, I'm doing everything I can to help him with this endeavor. This weekend, I helped him build a Nemesis Clone with an Atty 1092 atomizer-which was a nice father-son project. We made (2) coils that were 3mm and 6 wraps with a Kuro Koiler. Initially, he was using Charlie Noble juices with 6mgs of Nicotine, but he reduced that to 3mgs of Nicotine because he found he was vaping more than smoking–which is apparently the case with new vapers.

I was told I should get an ohm meter so we can test the voltage and resistance of his builds. Not sure whether to purchase a traditional multimeter or a vaping specific meter like a Smok Omni Tester or a Eleaf Meter.

I was also told I should consider getting him an atomizer with a larger juice reservoir or subtank. Sorry. I'm still trying to familiarize myself with the terminology. Two that were recommended were the Atlantis and the Kanger.

Any recommendations or advice is greatly appreciated.

Hello and welcome to the forum. Glad to have you here!

I prefer using an ohm reader for checking my builds. The better ones are made by USA Ohm meters. I use a DMM for checking the voltage of my batteries.

If you are new to mech mods and rebuildables I highly recommend you spend some time with Baditude (one of our resident battery/safety experts) and visit his blogs. You are now 100% in control of your own safety (and others around you). Make sure you purchase an ohm reader and a voltmeter or DMM so you can measure your builds, check for shorts and measure the remaining charge on your batteries.

Baditudes Blogs. The blogs that address battery safety, Ohm's Law, CDR (continuous discharge rating/Amps) and how they all work together are detailed below:

BATTERIES

Battery Basics for Mods: IMR or Protected ICR?
* Another essential read to understand which batteries are safe to use in mechanical and regulated mods. Includes a frequently updated list of recommended safe-chemistry, high-drain batteries with their specifications.

Purple Efest Batteries not as Advertised
* A cautionary blog that reveals that the purple Efest batteries may not have the specifications advertised. Also includes a commentary on "continuous discharge ratings" vs "pulse discharge ratings" of battery specs.

OHM'S LAW

Ohm's Law for Dummies (Vapers)
* My attempt at explaining Ohm's Law in layman terms and how it relates to vaping.

* As simple as it is to use, some people have a tough time grasping the concept. Warning: Includes graphic photos of mod explosions.

BATTERIES - WHERE TO BUY

Only buy batteries from a reputable supplier (not ebay or Amazon) as there are many counterfeit batteries being sold. Here are several reputable battery suppliers in the US.

* RTD Vapor
* Illumination Supply
* Lighthound
* Orbtronics

Yea, I prefer a DMM over those little mystery boxes myself

As a side benefit, it comes in handy for other stuff as well. Checking battery charge. Testing that non working plug i n the kitchen, checkin your car battery etc.



Your a cool dad


Can you adopt me?

Welcome! You defently should get a meter for safty to see where your coil is and to test for shorts. A vaping specific meter is what I use.

 

[RavenManiac]

Awesome info. Thanks! Is there a multimeter brand/model that you would recommend. I hear the Fluke 113 is really good for vaping, but it's a little pricey.

LOL You are too funny. I'm sure your parents would do the same for you.

Actually I don't try to push them because of cost. But you'll have a fluk forever. Many even come with lifetime warranty and have a registration card and can always be serviced, its all I own think the 113 is pricy check out the 87v lol

Its one of those things if ya get a fluke you never need to replace it. And its a secret but you can see videos of other companies testing their boards in assembly using a fluke hows that for irony lol

USAmade- bad to the bone, second to none

But check susans link

The cheap little box meters are fine, IF you are building in the 1+ ohm range, but their accuracy isn't good enough for significant subohm builds. I would trust one making a .8ohm coil on a mod that could handle a .5ohm build, I would never trust one with a .5ohm coil or lower under any circumstances.

It's a case where you have to have your own safety margin built in to your coils. Those box meters can be as much as .2ohm (or in rare cases more) off on their readings, with anywhere from .05 to .1 off being the norm. Stay high enough with your builds that a coil that ended up being .3ohms lower than the meter says is still safe and it's good enough. If you need to be more accurate than that then you need a better meter.

Wow! That 87v is pricey.

I checked out Susan's link and that's the second time someone has recommended USA Ohm Meters to me. It's clear that their meters are extremely accurate. I just wish they put more effort into their products aesthetics.

If you are unfamiliar with using a digital multimeter, here's a nice tutorial:

It looks like Klein is a good brand of multimeter, just not as expensive as the Flukes. Does anyone have any experience with the Klein brand?

 

[RamShot Rowdy]

My DMM only has a resolution of 0.1 ohms and I don't trust it for anything under 1.0 ohm. My USA Ohm Meters atomizer meter is supposedly accurate to within 0.018 ohms, so I use it to test builds.

 

[EBates]

Personally, I prefer to use the resistance box to and ohm meter. The primary reason is that the 'cheap' ones offer more chance for probe and meter lead issues. Had a Fluke that died, Now have two 'cheap' DMMs that I would not trust for measuring a sub ohm coil to be used on a mech mod.
I use the resistance box as a build stand and for initial check of the atty resistance. The final check is done on a regulated mod, where the atty gets a second check and a dry burn, to remove any manufacturing chemicals and fix any hot spot or hot leg issues.
I'm way too paranoid to build an atty and not double verify it is safe.
Good Luck

Klein is a top notch company with all things electric. I wont use any other brand in tools messing with electricity.

 

[Frenchfry1942]

I use a little cheapie eLeaf box initially. Then, my mod reads ohms, so I confirm it there. If they are within .1 ohm, that is fine.

 

[RavenManiac]

I'm thinking I should get both. The multimeter for more detailed info and the screw in type for a quick read.

I do like the Smok OmniTester because it measures both volts and ohms and even tests builds under load. Plus, it has a USB rechargeable battery, which is pretty cool. The only con is the display is limited to a tenths reading versus hundredths. Not sure if that's a big deal or not. I'd be interested to hear from anyone who has used the OmniTester or has other recommendations for a similar device. Thanks!

Okay, I decided to go with the USA Ultimate Ohm Meter. What case/LED combination is the most attractive and easy to read in your opinion?
