While an Om meter may tell you how close you are to reaching enlightenment, this Ohm Meter discloses your atomizer or cartomizer's resistance level as measured in... ohms. Maybe you have been using your heating element (atty or carto) for some time and are feeling it is not performing as well as it had been. Now you can know for sure. Or perhaps you have a number of attys and cartos laying around and don't anymore recollect which is which. Now you'll know which is the 1.5 ohm and which the 3 ohm. Now you'll know for sure whether you've got a dud on your hands. When there is no current flowing through the device, the led will read 1 on its lefthand side; reads from .01 to 9.99 ohms.
Use natively with 510 and 901/808D cartos and attys. Use a 510 to 510 Mega Connector to check your Ego batteries and the like.
Requires two AA batteries (not included).
