Hand held Brake fluid refractometer(NTR)
This Brake Fluid Refractometer is prism mounted in high impact plastic.Patent product.
All water-based solutions can make light bend. The bending of light increases at a rate proportional to the increasing solution concentration. This 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.
