This refractometer is designed to measure the following items:
A. The freezing point of Antifreeze based on Propylene Glycol and Ethylene Glycol. It can not measure the antifreeze based on methanol.
B. The freezing point of Automotive glass water. It can not measure the glass water based on methanol.
C. The concentration of Automotive Adblue (Urea)
D. The Specific Gravity (sg) of the rechargeable battery fluid.
It is equipped with Automatic Temperature Compensation (ATC), so that the fractometer is automatically adjusted to correct temperature discrepancies of environment temperature.
