The Acision RFA-554 gauges the freezing point of coolants and assesses the concentration of Ethylene/Propylene Glycol. This refractometer determines the freezing point of Propylene/Ethylene Glycol in the range of -50 to 0°C and the Specific Gravity of battery acid from 1.15 to 1.30, offering a swift reference for battery charge condition. It requires just 2 or 3 drops of solution for rapid and precise readings.

The Automatic Temperature Compensation ensures consistent measurements on a user-friendly scale. The device features a prism and lens with an easily adjustable focus, and it comes complete with a carrying case and calibration screwdriver.
