#1 Compact Battery Hydrometer Set



This tried and true Compact Battery Hydrometer design allows the user accurate and reliable specific gravity readings for a lifetime. This high quality tool will test your battery’s state of charge and give you an understanding of the overall health of your batteries. Its compact, heavy-duty design can monitor your flooded lead-acid batteries for decades and optimize the life of your expensive batteries.

Works well with large or small lead-acid batteries. The flexible rubber tip allows for use in tight spaces. This set includes our Wall Mount/Drip Cup System to keep your hydrometer safe and clean. Be sure to select which temperature base (60°F or 77°F) you would prefer and also whether or not you would like a Colored Zone Float or Non-Colored Zone Float. All of the floats have the same specific gravity range. Feel free to ask any questions as we always have technicians standing by to answer them.
