All water-based solutions can make light bend. The bending of light increases at a rate proportional to the increasing solution concentration. This Glycol/Brake Fluid Refractometer is a precise optical instrument that measures the concentration of aqueous solutions by measuring its refractive index. Its characteristics are small, light, take only a few drops of solution to use and it is very user friendly.

Features:

• Calibration screen
• Cushioned rubber eyepiece
• Non-roll stand
• Prism mounted in high impact plastic

Applications:

• Freezing points of:
  • Ethylene & Propylene Glycol coolants and battery acid level
