5-in-1 Refractometer for DEF Urea Concentration, Windshield Washer & PG/EG Antifreeze Freeze Point, Battery Specific Gravity - Refractometer for Coolant, Antifreeze, and Diesel Fluid

About this item

• Accurately measures the freezing point of ethylene glycol or propylene glycol-based antifreeze, with a range of -60°F to 32°F (-50°C to 0°C).
• Precisely reads the specific gravity of rechargeable battery acid (1.10–1.40 kg/L) to quickly indicate charge condition.
• Tests the freezing point of ethanol or isopropyl alcohol-based windshield washer fluid from -40°F to 32°F.
• Determines urea concentration in diesel exhaust fluid (DEF) from 30% to 35% with 0.2% resolution.
• Features automatic temperature compensation for fast and accurate results under varying conditions.
