2-in-1 Ohm & Voltage Meter

I was looking around and saw this new meter at My Vapor Store. It's like the ohm meter that is so popular, but it includes voltage as well. Looks like I pretty handy device.

2-in-1 Ohm & Voltage Meter

 

[devauto]

Thanks for posting this, it looks pretty handy ... I do have to wonder how accurate it is though ...

 

[Ed_C]

The claimed accuracy is 0.005Ohm or 0.2%, whichever is larger for resistance, but it doesn't say for voltage. I know the straight ohm meters like this seem to be pretty popular around here.

Ed.....
Might want to jump on this....NOW!!
MVS is a top-notch company to do business with.....and this is a HOT item -- and sells out FAST!!
Grab one while they still have 'em!! Methinks I'll do likewise....!!
Happy (vaping) Trails!

 

[Vapoor eyes er]

It's a one trick pony. Better to buy a digital multi tester. Bought a bunch last Christmas for $10, regular $40.00.
I've always owned one and use it to diagnose/ fix:
Vape probs, fridge, PC, stereo, car, home electrical...pretty well anything electrical and just too many things to list.

Oh, that! Yes, get it, it's a wonderful little gazinta to have, I got one early on after I started rebuilding coils, and I love it, but they go out of stock fast, so jump on it. It's not going to tell you voltage though, just ohms. That's enough really, to start, but for voltage you want this gizmo in the foreground:



It's another hard to get thing, but very nice to have. I got mine from Sunny Vaping, and they only had 5 left. I'd been wanting one for months. For $16.95 you can have one too. Very nice to have if you use mechs.

Sunnyvaping Volt Reading and Volt Drop Meter

They are out of them now, but should have more in a couple days.

Vaslovik, this one appears to be a new model that reads output voltage as well. That's why I brought it up.Two for the price of one.
Vapoor eyes er, surely a multimeter is a more versatile tool. I just thought this would handy for down and dirty checks.

Sure maybe I was lil' too harsh and as long as it keeps you happy and off the stinkies it's all good

 

[Ed_C]

Nah, you weren't harsh at all. I agree with what you said. I just know that those little ohm readers are popular and I though it was cool that they have now added voltage.

I have a multimeter but I might have to give this a go. Looks handy.

Ed,
looks like a good unit,
and from a reliable vendor.
real good option for those rebuilding coils....

Still you can't go wrong with a good autoranging digital multimeter

I have the ohm meter from MadVapes and as with the one the OP cites, you need a 510 to eGo adapter for most clearos. The problem is that the connection on most adapters is spotty. In a 10 pack, you might get 6 or 7 that work reliably. I recently got this 'well' adapter:

510 to eGo Adapter with Well

It has a spring loaded center pin which virtually insures a good connection. Good for eGo and 510 connections alike. It's 50 cents more than their regular 510 to eGo adapter.

I also have a multimeter and check the calibration of the ohm meter with the multimeter. The ohm meter is easier, quick check when you think the coil's getting gunked up and may need a cleaning and I always check before and after cleaning - tells me when a coil is ready to be pitched. One note - don't crank down on the clearos onto the connection - easy to do when it's dead and you don't think you're getting a connection - getting a clearo out of the well adapter would be harder to do but it's a better connection than most adapters.

 

[Ed_C]

Thanks for the heads up.Those spring-loaded adapters looks pretty nice.

 

[DaveOno]

It looks like a cool gadget. But why not get something more useful? Something that can check resistance on any coil and voltage of any battery, regardless of threading?

Craftsman Digi Multimeter, $19.99

And

From Harbor Freight, 7 function digital Multimeter for $5.49

(also useful for checking those AA and AAAs we all use.)

Beyond that, it is a cheap POS tool, when I need accuracy, I'll grab my Craftsman.

Be warned, it only checks voltage on a simple (non-voltage variable) ego-c battery. Don't know about mech mods. Please tell us when you get it.

[stylezuk]

It's what i have and not only handy to check ohms but is a good building tool as can place the atty on and not have to fiddle in lap or between hands, didn't realise what the other connection was for until read this, doubt I'll ever use it though

Looks like the meter in ed's link will check voltage on any mod with a 510 connection, one of the pics has a mech hooked up to it


While I have a multimeter and think they are a must, this meter sure would be more convenient for taking out of the house.

It's a nifty toy at a decent price. I'm not dissing it, but be aware of the following:

1) For e-cig use, we usually check voltage UNDER LOAD.
2) That would have been cool if it allowed you to screw the coil on one side and the battery/power on the other (an in-line meter).
3) Thus, the voltage you are reading is unloaded voltage...the actual voltage under performance can vary (voltage sag) depending on device.

With a DMM, you need a special tester (basically an atty connector with wires exposed) to test the volts/amps under load.

It's not a bad thing. 2 for the price of one. But just know what type of voltage reading you are getting with it. Unless I hear that it has a low resistance load (like 1.5 ohms or something) I assume it's got high impedance.

Someone correct me if it doesn't measure unloaded voltage. Still, it's not bad at that price. I'd put the $$$ toward a meter though. Some may feel too intimidated for a DMM.

 

[Grateful4jerry]

I was assuming it was for testing battery voltage only. Would there be a significant voltage drop even when mod isn't underload, or would you get a fairly accurate measurement of battery? Maybe I should stick to my multimeter

Basically, it depends on the ohms of the load, and the amp output capabilities of the battery. So ....it depends. lol.

For 18650 mechs with good batteries....not much sag on standard loads. (High drain battery, after all).
For a smaller regulated e-cigs....the lower the ohms, the more sag...because the battery has an internal resistance and can't keep up. Also...the electronics may limit it (and rightly so). Over-amping a battery is how it heats up and goes thermal.

Also, depending on how the voltmeter is, various regulated e-cigs boost the voltage to the VV setting and use PWM...so they (the volt meter) don't always give the proper reading. It depends again.

So what is it that you're testing? If for a mech, it would test battery voltage. But so could a meter without a special rig. Although a special rig is handy since it's hard to get the probe to stay on the center pin and not touch the shell and short it. You should probably take the battery out in that case...it's easier (when using a DMM).

So I guess you're right....more for testing unloaded battery voltage on mechs. Meh.

The other voltage stuff is a continual point of contention in the e-cig world. nm, I guess.

P.S.
Nice AVI. My late brother was a deadhead. No pun intended.
