Featuring a corrosion-resistant chrome-plated brass body and automatic temperature compensation, it delivers precise, reliable readings across a wide temperature range (-50ºC to 0ºC). Compact and portable, it comes with all necessary accessories for easy, on-site vehicle maintenance and fluid testing. ## Description The antifreeze refractometer can be used to measure the freezing point of glycol, antifreeze, coolant and battery acid. It can also be used to check the condition of electrolyte solution batteries. Specifications: Color: Black + Silver + Blue Material: ABS Measuring range: Ethylene glycol: -50ºC-0ºC Propylene glycol: -50°C - 0°C Cleaning fluids: -40°C - 0°C Battery fluids: 1,100-1,400 sg Ethylene glycol solution factor: 5 °C Propylene glycol solution factor: 5 °C Cleaning fluids solution factor: 10 °C Battery fluids solution factor: 0.01sg Package list: 1 x frost protection refractometer 1 x cloth 1 x pipette 1 x user manual 1 x mini screwdriver 1 x storage case with inner protective shellSize: (Dia.) X (H) 17 x 4 cm / 6.69 x 1.57 inches (approx.) Item Descriptions: This style is equipped with °C. By specifying the percentage, we can know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze. - There is also an additional scale for measuring the freezing point of the windscreen cleaning fluid. It is fully designed with ATC that automatically adjust to correct temperature discrepancies during use. Review: Love this! - Great product. Especially when you want to keep your car maintenance on point! Review: Tester - Works a treat as a mobile mechanic great for antifreeze checks but also use for adblue ## Features - This style is equipped with °C. - By specifying the percentage, we can know the freezing point of either ethylene glycol or propylene glycol based cooling systems. - And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze. - Use: this refractometer can be used to determine the ethylene glycol and propylene glycol concentration of the antifreeze of your car, solar system, heat pumps, the freezing point of windscreen washer water, heating system or other machines or systems. - High quality: our chrome plated brass body is resistant to chemical corrosion and wear resistant, the service life of the refractometer is increased several times than other aluminum housings. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B093Q98N3Y | | Best Sellers Rank | 5,085 in Automotive ( See Top 100 in Automotive ) 64 in Antifreeze & Coolants | | Brand | AOKUY | | Customer Reviews | 4.5 4.5 out of 5 stars (262) | | Date First Available | 28 April 2021 | | Item Weight | 235 g | | Material | Abs | | Package Dimensions | 20.6 x 8.5 x 5.5 cm; 235 g | ## Images ![Antifreeze Refractometer, Hand Refractometer Coolant Tester for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery Acid, Urea Concentration of - Image 1](https://m.media-amazon.com/images/I/719+v0WpSNS.jpg) ![Antifreeze Refractometer, Hand Refractometer Coolant Tester for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery Acid, Urea Concentration of - Image 2](https://m.media-amazon.com/images/I/71OC4RvKDwS.jpg) ![Antifreeze Refractometer, Hand Refractometer Coolant Tester for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery Acid, Urea Concentration of - Image 3](https://m.media-amazon.com/images/I/61pkIEINH3S.jpg) ![Antifreeze Refractometer, Hand Refractometer Coolant Tester for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery Acid, Urea Concentration of - Image 4](https://m.media-amazon.com/images/I/618LSGQoLcS.jpg) ![Antifreeze Refractometer, Hand Refractometer Coolant Tester for Ethylene Glycol, Propylene Glycol, Freezing Point of Cooling Water, Windscreen Water, AdBlue, Battery Acid, Urea Concentration of - Image 5](https://m.media-amazon.com/images/I/71SRgERvlcS.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Love this! *by S***T on 15 June 2025* Great product.
