FSTURIOS Coolant Tester, Accurate Dial Type Coolant Hydrometer Tester, 6/12/24V Car Battery Liquid Densitometer, Quality Automotive Antifreeze Tester for Ethylene Glycol Coolant

Practical Function: This dial coolant tester is designed to measure freezing point in winter and boiling point in summer. It helps users to know the status of coolant to ensure that the engine runs normally and maintains good performance under different temperature conditions

Reliable Quality: The transparent PC shell has good corrosion resistance, the top silicone ball is not easy to age and deform, and it can withstand frequent extrusion. This antifreeze tester can adapt to the complex working conditions to ensure long-term stable use

Quick Testing: Simply squeeze the silicone ball at the top to draw up the appropriate amount of coolant sample into the test device, and the results can be obtained quickly. It is easy to operate and requires no tedious steps or waiting, which greatly improves the efficiency of the test

Easy to Read: Our antifreeze tester ensures more accessible results with easy-to-read scales and pointers. The dial features a clear and intuitive dual scale display of F° (Fahrenheit) and C° (Celsius), which meets the habits and needs of users in different regions

Wide Application: This coolant hydrometer can be used to test battery liquid in 6V, 12V, and 24V systems, which meets the demand of daily use. It is ideal for checking antifreeze and coolant in the engine systems of cars, trucks, SUVs, and other common vehicles
