Dual Port Ohm Reader - Western Digital
2-in-1 Digital Ohm meter & Volt meter is designed for testing resistance and voltage of e-cigarette products. The size is very small, making it easy to test resistance and voltage at any time and place even for the most basic e-cigarette user. There are two ports on the Digital Ohmmeter & Voltmeter: The left one for testing voltage and the right one for testing resistance. (The ports are for eGo-threaded devices and the connector for 510-threaded devices.) LED display. Screw the atomizer onto the resistance port of the device for testing its resistance. The ohm reading will show in the LED display.
