Product Description

Digital 510 Ohm Meter Resistance Reader and Voltage Tester

This digital meter is designed for testing the voltage and the ohm(or resistance) of e cigarette products. Compact and portable design allows for you to carry it with you at all times if need be. The ports are made to be used with eGo threaded devices and has a connector for 510 threaded devices.

The 510 ohm Reader Meter integrated with dual function voltage tester and resistance checker both which are an essential tool when rebuilding coils. Reading the resistance on rebuilt and home made RDA coils is necessary part of coil building and meters such as this are a standard tool used by vapors and coil builders intending to wrap their own RDA and RDA coils.

Testing voltage and reading ohm levels is super simple with this reader. Flip up the "on" switch then use the meters right port for resistance testing and the left for voltage testing. These readings will instantly be displayed on the easy to read led screen.

Have No Choice !

Posted by Guido on Jul 3rd 2021

It has been a while since I bought this along with a bunch of other small items almost a year and a half ago. Just saw this again in my email, so I figured I should review the item.

This ohm tester was inexpensive, but it was still too expensive, only to discover that it was junk. I got a reading off it once or twice, but the 510 broke loose and rotated in the plastic housing. Everything inside is a blob of hot glue ! I scored a full on Coil Master 521 Tab with all the goodies (Not The Mini) for about $8 + Shipping at ejuicesteals com Now THAT has been a delight and I am glad I bought three of them lol
Possibly Usable !

As I screwed in a Used TFV8 Beast with juice In it, with the meter power ON, as soon as the connector was in far enough it read .25ohms but the tank was really loose and as I screwed it on farther it jumped around a lot from .25 all the way up to .63 but then as it got more snug on the threads it settled down to .19 but the tank wasn't all the way threaded yet, so I continued just until it stopped turning, BUT before I got that far the reading dissapeared and it would not give anything other than three dashes and the tank was a LONG way from being tight, or even snug. Turned it off and back on again and let it sit a min. ..--- just dashes! Start to unscrew the tank and numbers appear 7.52ohms, 2.83ohms, 5.08ohm, etc. etc. Tried an empty tank next, it is a brand spanking new TFV16 with a .17 coil in it and as it made contact it reads .22 screw it just a tad farther onto the post and --- (Dashes again. I had to tilt the tank side to side and the numbers jumped around and I got a .18 reading, and flickering back and forth between .17 and .20 over and over again, But that is a Premade screw in Coil and who cares what those read?

I spun on a Brand new TFV8 Beast tank with a Brand new/ unused RBA head and, ...... Absolutely NUTHIN' But Dashes no matter what I did. Screw it on farther,... or less, ... Wiggle and jiggle, ... Nothing but dashes. Maybe the RBA is shorted? I'll try a Brand New TFV12King with a never used RBA head in it and, ... Just dashes. Oddly I found that trying to tilt the top of the tank to the left it would read something, but is it a reliable reading? Not Sure. Screw the tank on a little farther and it goes back to dashes, tilt slightly and it comes back but jumps around from 2.09 to .74 to 1.38 ohms. Tilt top of tank to the right and dashes again. SO, I find that if you screw the tank on until it Just makes contact with the pin and screw it on very slowly and Stop way before it gets anything like tight, or even snug, it is more steady in its reading. But is it accurate, or even close, or even Far close? Who knows.

I screwed my Aspire CF battery onto it and it wouldn't read Anything, just dashes and Nothing would change that. SO it seems it is even More useless at reading voltage as it is at reading ohms. Oh Well, maybe I just got a bad one?

Either way you are going to want to stick a folded up matchbook cover on top of your batteries inside because they jiggle around and pop out of their socket because the spring is long and the batteries are short and there is too much clearance between the batteries and the battery hatch door.

If I spent more than $3.29 on this I would be fairly pissed. I'm not sure if I can use this as a temporary until I find a larger 521Tab (Not the Mini), ... but If not, then it will get fed to the recycle bin.

Ugh, I'm done messing with this thing for now.
Awesome

Good product
Terrible and unusable

This item was a waste of time and money. I understand why it was on clearance when I bought it, because I didn't even get it to do a reading once. I attempted to screw an RDA into it, and the connection to the unit itself came right out of the base, like it had completely corroded. I had to use pliers to remove it from my RDA.
Absolutely a case of "you get what you pay for" except considering the brand, I expected better.
Shaky at times

Use fresh batteries, other then that, does what it says for $.99
