High Accuracy Dial Antifreeze Vehicle Car Battery Hydrometer Tester
Precision-engineered dial design ensures ±0.005 specific gravity accuracy for reliable battery health diagnostics. Heavy-duty ABS casing with shock-resistant construction withstands harsh garage or workshop conditions. Transparent anti-spill tube allows quick, mess-free electrolyte sampling without opening battery caps. Dual-scale display (freezing point and specific gravity) instantly identifies weak cells or antifreeze concentration levels. Industrial-grade stainless steel hydrometer floats smoothly for consistent readings in extreme temperatures (-40°F to 140°F). Ideal for mechanics, fleet maintenance, and DIY enthusiasts testing lead-acid batteries in cars, trucks, or marine applications. Ergonomic thumb grip and compact size (5.2") fit tight engine compartments. Includes detailed color-coded interpretation chart for immediate action decisions. Exceeds ASTM E100 standards for professional-grade durability.
