The 510/901 ohm reader is an individual module that allows you to test your cartomizer or atomizer for ohm resistance. Simply screw on the atomizer/cartomizer, and a blue or red (choose option) LED will display the ohms with an accuracy level of +/- 0.2. When there is no current drawn, it will read "1" on the display which can be ideal for advanced users to get a certain ohm level when building atomizers. The ohm meter has a range from 0.01 to 9.99 ohms and is equipped with an on/off switch. With a test amperage of only 3 milliamps, the unit will avoid any heat or danger to the atomizer/cartomizer you are testing. The unit is power by a 2 AA batteries.
- Measures to the hundredth of an ohm (2 decimal places)
- Compatible with 510 and 808/901 connectors
