Kücheks 5-in-1 Automotive Battery Antifreeze Refractometer Afor Specific Gravity, Windshield Screenwash Fluid, Freezing Point Measurement Tester Meter Coolant Condition

● SCALES : (1) Battery Fluids, (2) Ethyln Glycol Freezing Point, (3) Prpyln Glycol Freezing Point, (4) Cleaning Fluids Freezing Point, (5) SRF1 - Screenwash antifreeze(IPA ), (6) Adblue● 1. Measuring 1.10 to 1.40 kg/l specific gravity of battery acid and provide a quick reference of battery fluid condition (density of the electrolyte and each scale division corresponds to 0.01g/cm3)● 2. Measuring -50 ~ 0°C freezing point of automobile antifreeze based on ethylene glycol or propylene glycol.● 3. Measuring -40 ~ 0°C freezing point of windshield washer fluid based on ethanol or isopropyl alcohol● Auto temperature compensation (ATC), rest easy that your measurements are always accurate regardless of temperature variation
