4-in-1 Antifreeze Refractometer Ethylene Glycol, Propylene Glycol in Antifreeze Freezing Point Temperature and

Key features

• The models have only one unit system: °F. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems. And they can also be used to test the concentration of ethylene glycol or propylene glycol in antifreeze Fluids.
• Ethylene Glycol: -84°F-32°F 0-70% VOL
• Propylene Glycol: -60°F-32°F 0-63% VOL
• AdBlue: urea concentration 30% - 35%
• Battery SG: 1.100-1.400sg
