High-Precision Antifreeze Tester & Refractometer
Accurate antifreeze concentration measurement with ±0.1% precision, ensuring optimal engine performance in extreme temperatures. Durable aerospace-grade aluminum body with scratch-resistant lens for long-term reliability in harsh garage or fieldwork conditions. Multi-scale calibration (C/F, ethylene/propylene glycol) for universal compatibility with all vehicle types—cars, trucks, heavy machinery. Ergonomic non-slip grip and compact design for single-handed operation during roadside emergencies or fleet maintenance. Optical prism technology requires just 2-3 drops of coolant, eliminating messy spills and wasteful traditional hydrometer methods.
