What Is a Refractometer? And Why You Should Be Using It?
A refractometer measures the refractive index of a liquid, which is affected by the concentration of dissolved solids or additives. By placing a drop of the metalworking fluid on the refractometer’s prism and measuring the refraction of light passing through it, the refractometer provides a reading that correlates to the concentration of the coolant additives. A refractometer is an important tool in metalworking fluids because it helps in determining the concentration or the ratio of coolant additives in the fluid. Read more…
