OHM meter recomendations?

[Jred10465]

I found one called "The Omnitester" on RTDvapor.com and I'm not sure if it's ok.
it describes it as:

The Omnitester

The Omnitester is a cool new gadget from SmokTech. This device allows you to check the resistance of any 510 or eGo-threaded atomizer. It also allows you to check the output voltage of your 510 device, including Pulse-Width Modulated devices, like the Zmax and even eGo batteries. You can also attach an atomizer and a device at the same time to test its voltage under load! The Omnitester has an internal battery, and comes with a USB to Micro-USB cable to charge it. There are a myriad of uses for a device like this. You can simply test your resistance and use it as an ohm-meter. You can also test the voltage drop of your mechanical mod by attaching a mod and an atomizer at the same time. You can even check the output voltage of a mod that's set to wattage mode and get results in real-time, instead of using an Ohm's Law calculator.

Does anyone else have any other recomendations?

Thanks!!

I use a USA Ohm Meter, which I've been really happy with. Seems pretty accurate when compared with the readings I get from a multimeter.

I have an ohms tester as you describe. I use that and I also use a mod to test. But, once the wick is in, I stay with the plain ohm tester.

That looks cool, doesn't say how accurate it is though.

I've been looking at these USA OHM METERS as they're supposed to be pretty accurate.

Unless you're super budgeting or doing very low ohms where you want 0.01 ohm accuracy, I'd recommend a regulated mod like a vamo, svd, e-lvt instead of a e-cig-only ohm tester.

A dmm multimeter is also a versatile option; you can measure voltage under load, which is not something you can measure with a those 510 interface ohmmeters.

the description says that this one does measure voltage under load. Do you have any specific recomendations? I only chose this one because it is being sold through a reputable site.

Ohhhhhhhhh!!! Coooool.

Yeah, that does sound worth getting.

I use the USA ohm reader. Works just fine

The downside to the Omnitester for some people, as I understand it, is that it only reads ohms in tenths. This could be problematic for vapers who build sub-ohm. Here's a post from Froth on this forum:


"I own one, I was curious about it and was already ordering a few things from litecigusa which has the Omnitester in stock. A couple of notes about it. The display is three digits but it DOES NOT read to the hundredth of an ohm, it only reads a single digit past the point or tenths only, the third digit is reserved for displaying a small O when reading ohms, and a small V when reading volts. Honestly that doesn't bother me because all the way down to .20 ohms I'm more than battery safe with a good amount of buffer zone. Since the resistance of a coil changes even after just a couple hours of vaping I don't really find the need to measure hundredths of ohms until you start going below .2, because the difference between .10 ohms and .19 ohms is significant as it can cross into over 40A of current draw and will overload most batteries, the difference of .19 ohms and .10 ohms is 20A, with 22A being drawn at 4.2V with .19 ohms and a whopping 42A being drawn at .10 ohms. So, if you plan to build below .20 AT AL L I would suggest a different ohm tester than the Omnitester. For what it's worth, I never build below .20 ohms and I am perfectly satisfied with the measurement of the Omnitester."


I believe the tester does not read battery voltage but instead reads voltage drop(?) and because of the placement of the posts, tube mods can be voltage tested but box mods may be difficult if not impossible because the mod will bang up against the other post. This could be important to some folks as well. I don't own one so I cannot personally attest to the accuracy of the Omnitester.

What would work best, one of those ohm meters or a multimeter?

Those look rather nifty, might have to snag me one-thanks for the link. Buying quality gear always pays off in the long run, I don't trust things that claim to do everything when they don't state how well they do it..ie gimmicky stuff, so no Omnitester for me!!

I'd be interested to know how to measure voltage under load with a dmm multimeter. Please could you explain how this is done. Thanks
