The Davtron M450 Digital Volt Meter is a small lightweight instrument that monitors the voltage of your aircraft precisely. The pilot can more accurately know the amount of capacity remaining in the battery when there is a low voltage condition.

Model 450 is an extremely useful instrument which helps the pilot get better and more reliable service from the electrical system.
