Top 5 Best Ohm Meters for Vaping – Our Reviews:

1. Eyotech 521 TAB V2 Multi-Function Ohms Meter 

521 Tab V2 by Eyotech is a multi-functional ohm reader that can accommodate all types of testing and is suitable for both beginners and advanced builders. 

Aside from being an ohm reader, this device also functions as a voltage reader and can even be used as a coil building deck to build coils easily. It uses a single 18650 battery and offers reverse battery protection. 

This ohm meter can measure a resistance range of 0.01-9.99 ohms and a voltage range of 0.3V to 9.99V. While resistance checking fulfills your coil testing, voltage measuring takes care of testing e-cigarette batteries. 

Moreover, the Eyotech 521 TAB V2 is capable of measuring any voltage drops and has a decent OLED display that is easily readable. 

It is built with a 510 threaded spring-load connection and provides a stable platform for building coils. You can also select from three settings: power mode, burning mode, and voltage vs. resistance switch. 


  • OLED display
  • Multi-functional meter
  • Measurer both batteries and coils 
  • Measures voltage drops 
  • Safety features 
  • Highly accurate and efficient 
  • 510 spring connection 


  • Design is not appealing but this is not a deal-breaker 

2. Geekvape 521 Tab Ohm Meter

This sleek and compact ohm meter from Greekvape is powered by a single 18650 battery and offers an ohm metering range of 0.01 to 9.9 ohms at a 33W output. The standard ohm meter reading is displayed on a bright orange LED easily readable display. 

When used in the fire mode, Geekvape 521 Tab meter can dry burn a 0.1-ohm atomizer without having to remove the device. This helps in quick and efficient testing, saving a lot of time often spent on redoing. 

The 521 Tab has a unique 510 threaded connection which is gold-plated and spring-loaded, making it an ideal meter for a wide range of coils. Overall, this is a great compact ohm reader to own.

Plus, it doesn’t hurt that it has multiple safety features for high temperature, low resistance, short-circuit, low voltage, reverse battery, and breaker protection. 


  • Bright LED display
  • Highly accurate and efficient 
  • Quick testing 
  • Heavy-duty 510 gold-plated spring connection 
  • Compatible with a wide range of coils 
  • Test firing and dry burn capability 
  • Compact and sleek design 
  • Wide range of safety features 


  • The battery needs to be bought separately 
  • Not compatible with short or inset 510 connection 
  • Not compatible with shorted systems 
  • Not compatible with atomizer using 18650 battery but has less than 20A output

3. Coil Master Digital Ohm Meter and Volt Meter 

This digital meter from Coil Master accurately measures a coil’s resistance and allows you to tune-in to your specific testing needs. The readings are precise and are neatly displayed on the OLED screen. 

It is compatible with both 510 and eGo threading atomizers, thus making it perfect for use with a majority of the tanks, clearomizers, and rebuildable atomizers. The holder is long enough for conveniently building coils and offers effective testing, effortlessly. 

The voltage meter precisely tests the battery efficiency, so you can tweak your battery for the perfect voltage output. It measures the voltage range of 0.01V-9.99V and the resistance range of 0.01-9.99V.


  • An ideal choice for building using mechanical mods 
  • Uses AA batteries that can be easily replaced 
  • Highly precise and accurate
  • Compatible with both 510 and e-Go threaded connections 
  • Compatible with a wide range of coils 
  • Long-lasting battery life 
  • Clear OLED screen 


  • Doesn’t offer much in safety

4. Eleaf ISMOKA Digital Ohm Meter and Volt Meter 

If you are looking to test both the voltage of your mod batteries and the resistance of your atomizers at an affordable price, Eleaf ISMOKA has got you covered. This device is extremely easy to use as you just need to screw your atomizer on the right and the meter displays the reading immediately and accurately. 

For battery readings, just screw your battery to the left side of this meter. 

This Eleaf device is compatible with 510, eGo, and 808D threaded connections, making it a great choice if you use a wide range of coils. 


  • High-quality build 
  • Extremely easy to use
  • Uses AA batteries that can be easily replaced 
  • Compatible with 510, 808D, and e-Go threaded connections 
  • Compatible with a wide range of coils

Wrap Up

It is important to test your coils occasionally. It doesn’t take much time and helps you enhance your vaping experience. 

Most of the popular modern vaping mods offer adjustable wattage settings and that makes it essential to have an accurate coil resistance. So, I strongly recommend that you use an ohm reader to avoid accidents arising from improper coil resistance.
