RHA***0ATC models are equipped with °F unit system. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol-based cooling systems. And this can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze liquids. It's FULLY EQUIPPED with ATC that automatically adjust itself to correct temperature discrepancies during use. Refractive index is very temperature dependent, it is important to use a refractometer with automatic temperature compensation to give you the most accurate measurement in any type of environment temperature. Capable of measuring with high accuracy and provides precise results. It's equipped with vivid and sharp reticle chart for easy and comfortable reading. It uses ambient light only and no batteries are needed. Made by experienced craftsmen and are unlikely to break down!
