ABSTRACT:
A device for indicating the specific gravity and/or the level of the electrolyte in a wet storage battery with the device having a magnetically actuated switch which is energized by a magnet on a floatation member which senses both specific gravity and the electrolyte level. An adjustable bias magnet is provided to modify the magnetic force applied by the first magnet on the switch to accommodate for manufacturing tolerances in the device and also to accommodate for dimensional differences in battery construction.
