Glycol Refractometer – Automatic Temperature Compensation (Fahrenheit Units)



  • Equipped with scale measurement which provides direct reading.
  • Uses ambient light only which means battery or power source is not required.
  • Heavy-duty and lightweight with its aluminum construction.
  • Cushioned with soft & comfortable non-slip rubber.
  • Durable and built to last long.


– This unit reads only Fahrenheit. With the indication of the percentage we may know the freezing point of either ethylene glycol or propylene glycol based cooling systems.  This aids in figuring the concentration of a particular glycol fluid.
– The Glycol Refractometer is designed for testing for concentration of glycols. With the indication of the percentage you may know at which temperature the fluid will be frozen for both propylene glycol and ethylene glycol.
– It’s FULLY EQUIPPED with Automatic Temperature Compensation that automatically adjust itself to correct temperature discrepancies during use. Capable of measuring with high accuracy and provides precise results. It’s equipped with vivid and sharp reticle chart for easy and comfortable reading.
