Worried about your vehicle's coolant or battery? This Ade Advanced Optics refractometer takes the guesswork out of maintenance. It's super easy to use - just place a few drops of liquid on the prism and look through the eyepiece to get an accurate reading of freezing points for both propylene and ethylene glycol based cooling systems. The scale goes from 32°F all the way down to -60°F, plus it automatically compensates for temperature changes. But that's not all - you can also use it to check the strength of electrolyte solution in batteries. The high-quality optics give you crystal clear readings, and the ultra-smooth focusing makes it simple to get precise measurements every time. Perfect for cars, tractors, tanks, ships - basically any transportation vehicle that uses glycol coolant or acid charging liquid. This portable tool is a must-have for any serious mechanic or DIY enthusiast who wants to keep their equipment running smoothly through every season.
