4-in-1 Refractometer for Ethylene & Propylene Glycol Antifreeze, DEF, Battery Acid & Windshield Fluid – Accurate ATC Tester with °C Scale for Coolant Freezing Point & SRFI, Automotive & Industrial Use

4-in-1 Refractometer for Ethylene & Propylene Glycol Antifreeze, DEF, Battery Acid & Windshield Fluid – Accurate ATC Tester with °C Scale for Coolant Freezing Point & SRFI, Automotive & Industrial Use

• MULTIFUNCTIONAL TESTING: 4-in-1 refractometer designed to measure the freezing point of ethylene glycol & propylene glycol antifreeze, specific gravity of battery acid, windshield washer fluid, and urea concentration in DEF.
• ANTIFREEZE FREEZING POINT: Measures ethylene glycol (-50°C to 0°C) and propylene glycol (-50°C to 0°C) antifreeze freezing points, ensuring optimal protection for your vehicle in extreme weather conditions.
• BATTERY ACID SPECIFIC GRAVITY: Quickly tests battery acid's specific gravity (1.10 to 1.40 kg/l) to determine charge condition, helping you monitor battery health and avoid unexpected failures.
• WINDSHIELD WASHER FLUID FREEZING POINT: Accurately measures the freezing point of windshield washer fluid (-40°C to 0°C) based on ethanol or isopropyl alcohol, with SRFI scale to ensure clear visibility in freezing temperatures.
• DEF UREA CONCENTRATION: Accurately measures DEF (Diesel Exhaust Fluid) concentration (30% to 35%) to ensure your vehicle’s emissions system is operating efficiently and effectively.
• AUTOMATIC TEMPERATURE COMPENSATION (ATC): Features ATC for precise readings across varying temperatures, eliminating the need for manual adjustments and providing quick, reliable results.
• EASY TO USE & PORTABLE: No batteries required—simply place 2-3 drops of fluid on the prism for fast, accurate readings. Durable, compact, and portable design for convenience on-the-go.
• EXCELLENT CUSTOMER SERVICE: We pride ourselves on providing outstanding customer service with fast support and assistance to ensure your complete satisfaction with your refractometer purchase.
