Antifreeze Refractometer – 3-in-1 coolant Tester for Checking Freezing Point, Concentration of Ethylene Glycol or Propylene Glycol Based Automobile Antifreeze Coolant and Battery Acid Conditio

• Function 1: Measuring freezing point temperture of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale range: ethylene glycol base: -84°F-32°F, propylene glycol based -60°F-32°F
• Function 2: Measuring concentration of ethylene glycol or propylene glycol based automobile antifreeze coolant. Scale Range: ethylene glycol base: 0-70% propylene glycol based 0-63%
• Function 3:Measuring specific gravity of battery acid and provide a quick reference of battery charge condition. Scale Range:1.100~1.400kg
• ADVANCED AUTOMATIC TEMPERATURE COMPENSATION（ATC）TECHNOLOGY: Adjust Automatically to Compensate for Temperature, Which makes it even easier to get fast results.
• PORTABLE ANTIFREEZE REFRACTOMETER: Easy to use, sturdy design, compact in size and light in weight, convenient to keep up and carry around

The Tiaoyeer Antifreeze refractometer is a portable multiuse tool for automotive owners,you can use it for testing the freezing point for the antifreeze fluid based on ethylene glycol or propylene glycol, you can use it for testing specific gravity of battery acid and provide a quick reference of battery charge condition, you can use it for testing urea concentration in automobile diesel exhaust fluid (DEF), you can also use it for testing windshield washer fluid based on ethanol or isopropyl alcohol. 4 Fuctions in one light and small instrument, with this refractometer, you can know the level of your regular automotive fluid quick and easy, help you protect your automotive engine. Warning-Maintenance: 1.Calibration liquids can use clean water. This product does not require frequent calibration. The temperature of the liquid to be measured should be close to the temperature of the prism to measure the data is accurate. 2 .The instrument is resistant to abrasion and corrosion resistance.Can be measured acidic and alkaline and other general corrosive liquid. But we do not recommend measuring these liquids for a long time. The residue should be cleaned immediately after measurement. 3 This is an optical instrument. Do not need regular maintenance. But you have to be careful, the vast majority of damage is due to fall, which will cause the instrument difficult to repair.
