Antifreeze Coolant Tester Function 1: Measure the freezing point temperature of ethylene glycol or propylene glycol based automotive antifreeze. Scale range: glycol-based: -84°F-32°F, propylene glycol-based -60°F-32°F
Antifreeze Coolant Tester Function Function 2: Measure the concentration of ethylene glycol or propylene glycol-based automotive antifreeze. Ratio range: glycol-based: 0-70% propylene glycol-based 0-63%
Antifreeze Coolant Tester Function Function 3: Measure the specific gravity of battery acid and provide a quick reference of battery charging condition. Weighing range: 1.100~1.400kg
Widely Use: Just drop 2 or 3 drops and wait for few seconds to get the accurate value. Optic lens no battery required, hold the refractometer up to the light and look scale through the eyepiece. Adjust Automatically to Compensate for Temperature, Which makes it even easier to get fast results.
Its Easy : its easy to use, sturdy design, compact size, light weight, easy to carry around
