DXNQ 4-in-1 DEF Antifreeze Coolant Refractometer with ATC, Hand-Held AdBlue Coolant Tester Refractometer with Storage Box, Freezing Point Meter for Automobile Antifreeze System

Specification: Material: Aluminum, Silicone Quantity: 1 PCS Weight: 0.5 lb Size: 1.4 × 1.4 × 6.3 inches Package Includes: 1 Antifreeze Refractometer, 1 Dropper, 1 Screwdriver, 1 Cleaning Cloth, 1 Storage Box Feature: Accurate, Handy, Practical Fit Type: Universal Fit Would you like to consider the antifreeze coolant refractormeter? -The refractometer includes a protective cover that safeguards the prism during storage and enhances measurement stability. -The scale is distinctly marked for easy reading and interpretation of results. -It operates within a temperature compensation range (ATC) of 10°C to 30°C (50°F to 86°F), ensuring accurate measurements across different environments. Measuring Range: -Specific gravity of battery acid: 1.10 to 1.40 kg/l -Urea concentration in diesel exhaust fluid (DEF): 30% to 35% -Freezing point of windshield washer fluid (ethanol or isopropyl alcohol): -40 to 0 ℃ -Freezing point of automobile antifreeze (ethylene glycol or propylene glycol): -50 to 0 ℃ Notes: -The instrument is calibrated before factory shipping and is ready for immediate use. -If the scale is not clear, you can gently rotate the eyepiece to adjust it for clearer readings. -Avoid overstressing the eyepiece; if you cannot adjust it in one direction, try turning it in the opposite direction. -For calibration, add a few drops of distilled water onto the prism, then adjust the zero-setting screw until the reading aligns with the 0 scale. Clean the prism thoroughly before any testing. -Use the instrument with care, avoiding any loosening of connected parts, impact, or excessive vibrations that could affect performance. -After use, do not rinse the device in water; instead, use a clean soft cloth to wipe it down carefully to prevent scratches or damage to the prism. -Please handle carefully to prevent loss of components and ensure proper storage. -It's recommended to store the instrument in a dry place, free from corrosive gases, to maintain its precision and long-lasting performance. 【Enhanced Clarity】: The refractometer features an optical glass prism that enhances clarity by 1.5 times, paired with a high light transmission rate. This allows for precise measurement of the freezing point of antifreeze, so you can make informed decisions about your car's cooling system. 【Durable Construction】: The refractometer's aluminum body is finished with chrome plating, offering high hardness, wear resistance, and protection against rust and corrosion. You can trust this long-lasting tool that withstands frequent exposure to automotive fluids. 【Non-Slip Grip】: The tail section of the refractometer features a textured rubberized sleeve, which provides a comfortable and secure grip during operation. It allows for easy rotation and handling, minimizing the risk of slips that could compromise the accuracy of your readings. 【Use Instructions】: First, open the daylight plate and clean the prism gently with a soft cloth. Second, add a few drops of the test fluid onto the prism and close the daylight plate to secure it. Next, look through the eyepiece, directing the prism toward a bright light source for visibility. 【Broad Application】: This refractometer is ideal for various applications, including windshield washer fluid, antifreeze, diesel exhaust fluid (DEF), and electrolyte measurement, among others. You can refer to the measuring ranges listed below for some specific applications. See more product details
