The Rhino Duo-Chek Engine Coolant and Battery Test Refractometer is accurate. It stands out in the crowd. Why test engine coolant? Everyone knows that the proper concentration of engine coolant will keep the engine block from freezing and cracking in the winter months. On the other hand, the engine coolant will keep the engine from boiling over in the summer months. But did you also know that: Under Concentration of coolant/anti-freeze will cause: liner or water pump impeller cavitation general corrosion deposits on heat transfer surfaces plugging of the system with corrosion products Over Concentration...
