5 in 1 Coolant DEF(Adblue) Refractometer ATC, Automotive Coolant Tester for Battery Fluid Windshield Cleaner

The RHAN-504A model handheld antifreeze, Adblue and battery acid refractometer has four functions:

1. It measures the freezing point temperature of ethylene glycol or propylene glycol - based automotive antifreeze. The reading indicates the temperature at which the tested solution begins to freeze.
2. It measures the freezing point temperature of windshield cleaning fluid.
3. It measures the urea concentration in Diesel Exhaust Fluid (DEF) to determine whether the solution meets the required standards.
4. It measures the specific gravity (SG) of battery fluid, to determine battery health.
5. 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.
