510 Voltage Indicator meter
This 3 digit Red LED display will show the voltage of an attached DC power source with an accuracy of .005 volts!
These are assembled into a small smoked cartomizer tank tube with chrome510 male and female cap and connectors. This voltage meter will show voltage of a standard non regulated battery and voltage under load with an atomizer or clearomizer attached. This meter will NOT work testing voltage on devices that use switching or pulsing regulators (vv/vw devices). With vv/vw devices the meter will NOTshow loaded or live voltage when a clearomizer or atomizer is connected.
