Davtron's Model 450 voltmeter 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. Also of great
importance is the voltage at which the battery is being charged. Overcharging can lead
to excessive water loss and battery failure. Model 450 is an extremely useful instrument
which helps the pilot get better and more reliable service from the electrical system.
