Offer

Product description

  • Stable Readings: Built in ATC function for environments from 10°C to 30°C effectively eliminates the influence of ambient temperature differences on measurement results, allowing direct reading of calibrated temperatures.
  • Four in One Design: This refractometer coolant tester integrates four key tests, accurately measuring automotive urea, battery fluid specific gravity, antifreeze freezing point, and windshield washer fluid, it is an efficient vehicle maintenance tool.
  • Measurement Range: Urea concentration 30%-35%, battery fluid specific gravity 1.10-1.40 kg/L, antifreeze -50°C to 0, windshield washer fluid -40°C to 0. Easy Operation: Antifreeze refractometer ethylene glycol, propylene glycole, Simply add 2-3 drops of the test solution to the prism, align the eyepiece with the light source, and read the scale result.
  • Durable Design: The antifreeze refractometer with automatic temperature compensation uses alloy chrome plating technology and golden ratio cutting, improving durability and extending service life.
