  • Professional-Grade 5-in-1 Diagnostics – This high-precision refractometer is the ultimate shop tool for cooling systems, batteries, and emissions. Whether you're a master technician or a DIY enthusiast, get instant, lab-quality readings for Ethylene/Propylene Glycol, Battery Acid, DEF, and Washer Fluid.
  • Precision Cooling & Antifreeze Testing – Protect your engine from extreme temperatures. Accurately measure the freezing point of glycol-based coolants from -60°F to 32°F (-50°C to 0°C). Perfect for ensuring winter readiness and preventing costly radiator or block damage.
  • Rapid Battery Health & DEF Analysis – Stay ahead of maintenance with a dedicated Specific Gravity scale (1.10–1.40 kg/L) for rechargeable batteries and a high-resolution DEF (Urea) scale (30%–35%) with 0.2% accuracy. Essential for maintaining peak performance in modern diesel engines and lead-acid batteries.
  • Advanced ATC (Automatic Temperature Compensation) – Eliminate the guesswork. Our integrated ATC technology automatically adjusts for ambient temperature shifts, ensuring your readings remain pinpoint accurate in the heat of a busy shop or the cold of a driveway.
  • Built for the Professional Garage – Engineered for durability and ease of use, this kit includes a high-quality prism and a non-slip rubber grip. It provides clear, high-contrast optics that are easy to read even in low-light conditions, making it a staple for any serious tool chest.
