3-in-1 Antifreeze Coolant & Battery Tester - Fahrenheit Refractometer For Automotive Maintenance

About This Product

Hey car owners!

This handy little 3-in-1 refractometer is like having a mini automotive lab in your pocket.

No batteries needed - just a few drops of fluid and you'll know exactly what's going on with your cooling system and battery.

For antifreeze, it measures both freezing point (ethylene glycol: -84°F to 32°F, propylene glycol: -60°F to 32°F) and concentration levels (0-70% for ethylene, 0-63% for propylene).

Plus it checks your battery acid specific gravity from 1.100 to 1.400 kg/l to see if your battery's actually holding charge.

The automatic temperature compensation means you don't have to worry about room temperature affecting your readings.

Made from durable aluminum alloy with high-quality optics, it comes with everything you need in a compact case: the refractometer, cleaning cloth, screwdriver, pipettes, and manual.

Way more accurate than those old-fashioned floating ball testers and way cheaper than digital meters.

Perfect for DIY mechanics, weekend warriors, or anyone who wants to avoid expensive cooling system repairs or unexpected battery failures.

Seriously, for less than what a mechanic charges for one diagnostic check, you can own this tool and test your fluids whenever you want!
