Monitoring voltage on a project can be very important, especially if it is running on batteries! This panel mount volt meter is accurate to 0.1V and can read between 4.0 and 24.0 VDC making it ideal for automotive, 12V marine, or other applications.

To use, connect the gauge to the power source you wish to monitor. On the back of the gauge are two 0.250″ spade terminals. Once connected, this gauge will display the voltage as long as power is provided. Mounting the gauge is quite easy; it is designed to fit in a 29mm diameter hole and can be used with panels up to 7mm thick.
