About This

• Measuring Freezing of automoblie antifreeze based on ethylene glycol or propylene glycol -58℉ to 33.8℉. Measuring Specific Gravity of battery acid 1.10 to 1.40Kg/L. Measuring of Windshield Washer Fluid based on ethanol or isopropyl alcohol -40℉ to 33.8℉. Measuring Urea Concentration in automobile diesel exhauset fluid (DEF) 30% to 35%
• With automatic temperature compensation, after calibration at 20° ambient temperature, it can be read directly as long as the use temperature is between 10 and 30°, without affecting the accuracy.
• Copper chrome-plated process, heavier weight, heavier than aluminum fittings, higher durability, generous and beautiful, friction-resistant, drop-resistant
• High-definition prism for clear data visibility, easy operation and cost savings，for Automobile Antifreeze System, Diesel Exhaust Fluid, Battery Acid and Windshield Washer Fluid
• It doesn't require calibration before first use,The refractometer comes calibrated and is ready to use out of the box.
• Easy operation and save big: just need 2-3 drops of solution, you can get accurate readings.Clean the instrument between each measurement using a soft, damp cloth. Failure to clean the prism on aregular basis will lead to inaccurate results and damage to the prism's coating.
