4 In 1 Car Refractometer For Antifreeze And Coolant, Battery Acid Specific Gravity 1.10 To 1.40, Windshield Washer Fluid Ethanol Or Isopropyl, And Diesel Exhaust Fluid Urea Concentration, Copper CNC Machined Sensor
✔️ Reads antifreeze freezing point, battery acid SG, washer fluid, DEF
The all-in-one refractometer is designed for automotive service and DIY projects, letting you quickly verify antifreeze, battery acid, windshield washer fluid, and DEF concentration. It arrives calibrated and ready to use out of the box, with automatic temperature compensation for reliable readings across typical garage temperatures. The copper chrome-plated sensor and high-definition prism deliver clear, durable performance in tough environments.
✅ Copper chrome-plated sensor improves durability and longevity in automotive use
✅ Measures antifreeze freezing point from -58℉ to 33.8℉ with automatic temperature compensation
✅ Reads battery acid specific gravity from 1.10-1.40 Kg/L
✅ Detects DEF concentration from 30% to 35% with ambient temperature compensation
💡 What is a car refractometer used for in automotive maintenance and how does it work with multiple fluids?
A handy guide to using it effectively on common automotive fluids.
- It measures antifreeze freezing point (-58℉ to 33.8℉) with automatic temperature compensation
- It reports battery acid SG (1.10-1.40 Kg/L) for battery health
- It evaluates windshield washer fluid ethanol or isopropyl content (-40℉ to 33.8℉)
- It checks DEF concentration (30%-35%) for proper after-treatment performance
