Our In-Line Voltage Indicator features a bright red 3-digit LED display that displays the voltage of your variable voltage or standard voltage mod with an accuracy of 0.005 volts! The voltage indicator is built into a bright orange cylinder with 510 connections on either end; simply connect it in-line between your atomizer and your mod, and see the voltage under load! Reads 2.8V to 25.2V, in 2-second intervals. Pick one up today for all your in-line voltage indicating needs!
These indicators may not work properly with devices that use switching or pulsing regulators; in that event, the display will simply flash to notify you of the error.
