Suggestions for an ohm meter?

[Rourke]

I had a cheap $10 one that I got off ebay and it broke within 2 weeks. Right now I only have a lp reomizer but I plan on getting the bf Odin. Any suggestions for an ohm meter that will work well on both those attys that is also durable and accurate. Thanks for all your help Reoville.

Was your cheap one like this? eLeaf Atomizer Resistance Tester Ohm Meter Reader Black - black ohm meter, ohm meter, eleaf ohm meter, ohm meter vape, ohm meter 510

I suggest a inexpensive multimeter,

Mine was even cheaper it only had the 510 connection.

I got mine from rtd vapor and it measures right on the money every time. I first bought one off ebay and it was ALL over the place. total waste of my money! just my

Got one of these a while back
It is accurate
Ohm Meters

They will be restocking in a few days

My old Multimeter would not allow me to check the Ohms by taking the battery out; and touching the leads to the spring and firing pin.

But THIS ONE from Staples does allow me to check the Ohm by touching the spring and firing pin.

Multimeter will be accurate and has other uses. The 510 box ohm meters are convenient and some even have dual purposes like this one 2-in-1 Ohm & Voltage Meter but if you have a need to check the output voltage of 510 threaded manual button batteries or mods using the female thread then maybe its time to PIF it.

Stay away from the 510 style ohm readers. I've had 6 of them all from different places and all 6 broke in various ways. I dropped one, it stopped reading. I tightented down the screws on my Odin and another one stopped working. I dropped one and the 510 insulator popped up, stopped working...6 @ $15-20 a pop....just invest in a decent DMM.

Huh? Then where do you suggest putting the RBA to build the coil, and to get a coil reading?? Most of us use this type of Ohm Meter.

....maybe one of these.

I use a smok omnitester and I love it to bits, reeks of quality. the only thing is that it only has one decimal place, so if you're subohming you would want to A-B it with a multimeter because the difference between 0.10ohms and 0.19ohms could make a huge difference concerning safety

 

[ed101z]

That's handy for many things, but not for actually mounting the coil on the RM2. I'll just stick with an Ohm meter with a 510 connection.

I recommend this for building coils and testing them (without the battery):

It's quite stable if you place it in one of these (I got mine from J-Wraps):

I own and use both the cheap little 510 ohm checker and have a multimeter. If I could only have one it would be a multimeter. But check on the resolution many will only read tenths not hundredths. With a 2 ohm coil no big deal, but at sub ohm .25 vs .3 those hundredths matter.

I like the looks of this one, based on the reported specifications:

OHM Meter with Voltage Adapter

Basic accuracy is 0.005Ohm or 0.2%, whichever is larger. When the measurement is below 1.00Ohm, the meter will display mOhms, or 1/1000s of an Ohm, instead of Ohms. When displaying mOhms, the decimal point is not displayed.

Don't care about the kinda weird voltage check option. (Have other/better meters for that.)

Not so sure about the 510 connector though, specifically the center pin connection. Any comment?

The limitation with multimeters is accuracy, due to the lowest resistance range being usually 0 to 200 ohms. So when we measure a coil, we are right at the very bottom of the measuring range, which is not good for accuracy. IF the multimeter had a 0 to 2 ohms range or even a 0 to 20 ohms range the accuracy would be a lot better.

Below 1 ohm, an atty reader is probably the preferred device, even if its not that accurate, it would still be a lot better than a multimeter IMO.

Further information, not necessary to read, may cause a headache for some readers:

A multimeter is designed to test using minimal test current to avoid damaging components or affecting the circuit it is measuring, that is why they are a high impedance test device, and this is its main limiting factor for reading low ohms. An atty checker on the other hand doesn't care about damaging sensitive electronic components and might push 50mA through a coil to measure the resistance more accurately, whereas a multimeter would pass maybe 1/1000 of that test current (I don't know exact figures).

Another accurate way of checking ohms for DIY type people would be to get a module from ebay that can do constant current (for just a few dollars) and set it for 1 amp using your multimeter's current measure function. Then run the 1 amp current through your coil with alligator clips on the atty posts, and measure the millivolts across the coil with your multimeter. Millivolts will equal milliohms with the 1 amp current flowing. Another application of Ohm's law, V=IR, or in this case, R=V/I.

A cheap atty tester and a $1.50 LED voltage module are what I use most of the time, but a means of testing an atty while its attached to a mod is also occasionally needed and this is where a multimeter comes in handy, or an adaptor with leads coming from the atty reader. A nice DIY modification for an atty reader would be adding 2 banana sockets so you could use multimeter test leads on it. Some of them don't have enough room for the banana sockets though. I think I would like to do this.
