Essential for Automotive & DIY Maintenance: Density tester for car owners, mechanics, and hobbyists to test lead‑acid batteries in cars, trucks, motorcycles, boats, and solar power systems Precise Electrolyte Measurement: Accurately measures battery acid/alkaline solution density from 1.10‑1.30 g/cm³, providing reliable data to assess battery health and charging status Compact & Portable: 275mm (10.8‑inch) length with lightweight build, fits easily in a tool pouch or glove box for roadside checks, garage use, or fleet maintenance Glass & Rubber Construction: Battery hydrometer electrolyte tester is Made of glass with a flexible rubber bulb, and designed for clear visibility of float readings Easy‑to‑Use Design: Simply immerse vertically into battery cells, squeeze the bulb to draw electrolyte, and read density directly from the calibrated float scale—no power or calibration needed 1 1 1 1 1 1. Professional for measuring acidity and storage battery solution, provides you a more exact data.
2. The high-quality glass rubber material is more conducive to observing the value and brings more convenience to your inspection.
3. Small and light in weight, and convenient for you to carry, it can reduce your burden.
4. When using, you just need to put the meter vertical immerse in a transparent container, then you can read electric liquid density from the table at any time.
5. Its main function is for measuring electric battery fluid density, you can use it in any car.
