Description REFRACTOMETER ANTIFREEZE GLYCOL 1.100-1.400SG ATC 3-in-1 Refractometer, tri-scale design uses for testing freezing point & concentration of either ethylene or propylene glycol-based cooling systems & testing ethylene or propylene glycol-based anti-freezing liquids. Can also measure specific gravity of battery fluid. Monitor reliability of your battery charge & health condition Check freezing point of your car cooling system Be aware of the status of your car coolant Ensure all is working properly and not causing problems like rust, prone to freezing, poor charging, poor cooling, etc. Specifications Measuring Range Ethylene Glycol : -60~0°C (66.6%-0%) Propylene Glycol : -50~0°C (62.4%~0%) Battery Fluids SG : 1.100 – 1.400kg/l Division Ethylene Glycol : 5°C Propylene Glycol : 5°C Battery Fluids SG : 0.01kg/l Accuracy Ethylene Glycol : ±5°C Propylene Glycol : ±5°C Battery Fluids SG : ±0.01kg/l ATC 10-30°C Length 152mm Weight 91g
