-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.
