The REDARC 52mm dual voltage gauge is ideal for monitoring battery systems mounted in 4WD's, Campers, Caravans, Motorhomes and other similar vehicle applications. The LCD/ LED display allows you to monitor the charging performance of both your main and auxiliary batteries.
In the event of an alternator or system failure, the voltage reading on the gauge will be low and drop as the battery discharges. In the event of an overcharge condition, the voltage reading will climb above its normal zone. The G52-VVA gauge also has pre-set alert levels (<11V and >16V) to notify you of these situations by changing the gauge backlight colour to either amber or red, and initiate an audible beep when the vehicle's ignition is on.
