The **Gefo S** is a large, high-precision hydrometer model featuring a curved glass cylinder. It is specifically designed for the exact checking of electrolyte density in large-capacity batteries and stationary accumulators, where maximum accuracy is required.
Its robust construction and large size ensure stability and accuracy during measurement. Precision: The combination of a large scale and minimal graduation ($0.005\ \text{g/ml}$) allows for an extremely precise density reading. Ideal for: Large vehicle batteries (trucks, buses, earth-moving equipment) and stationary accumulators (industrial systems, backup power systems).
