Merlin Equipment Smartguage 12/24V

SmartGauge is reknowned as The World’s Most Accurate
Battery Monitor. It’s also the easiest to install and use.
SmartGauge overcomes all the problems and disadvantages
commonly associated with conventional amp-hour based
battery monitors. These include: Loss of synchronisation,
display inaccuracy, requirement of regular resetting, complex and time consuming installation and requirement that
the user has to have an understanding of batteries.
Once users understand the level of power left in their
battery they can answer highly useful questions like “are
the batteries charged yet?”, “When should I start the engine/generator?”, “Is there enough power to run that piece
of equipment?” – if operators of vehicles/equipment not
normally versed in the way of batteries can answer those
questions, you can improve reliability & efficiency of your
fleet by ensuring that batteries are properly cared for.
