Automotive Coolant DEF(Adblue) Refractometer ATC, Fahrenheit DEF Urea Concentration Tester for Coolant Battery Fluid

The RHAN-757A Handheld Antifreeze and DEF (Adblue) Refractometer has three functions:

1. It can measure the freezing point temperature of ethylene glycol or propylene glycol - based automotive antifreeze. The reading indicates the temperature at which the measured solution starts to freeze.
2. It measures the urea concentration of DEF (Adblue) to help manufacturers detect whether the concentration of vehicle urea solution products meets the exhaust emission standards.
3. It measures the specific gravity (SG) of battery acid. Specific gravity is the density ratio of battery acid to water, which is used to indicate the charging state of lead - acid batteries. The higher the specific gravity value, the more fully the battery is charged.

This model is excellent for automotive maintenance professionals, fleet service providers, and manufacturers who require a versatile, reliable tool for monitoring multiple fluid systems in vehicles. Its compact design, ease of use, and multi-functionality make it a valuable instrument in both workshop and field environments.
