The Megger 2001-692 8-Channel Digital Hydrometer Kit accurately and quickly determines specific gravity of flooded cells. Simply draw the electrolyte into it; the specific gravity and temperature are determined in five seconds. It provides memory for both temperature and specific gravity for eight tests of 256 cells each. The stored data can be easily transferred to the accompanying data logger. The data logger can hold 8 separate sets of test data. The data can then be easily imported directly into a Megger Power DB battery report from the data logger.
