This refractometer has an exclusive scale for measuring specific gravity of battery fluid and forchecking the freezing temperature of ethylene glycol and propylene glycol which are used as antifreeze mixture in automobiles, thermal catalyst for solar power systems and other industrial applications. MASTER-BC is the successor model to the conventional BC-2E. The scale is graduated in °C. NEW material (which is durable for salty and acid sample) is adopted.
