Maintaining proper concentration control is essential to increase fluid performance and longevity. Eriez HydroFlow offers a number of different refractometer styles. Portable refractometers require no batteries. They feature a large, easy-to-read scale that is available in two ranges, 0-10° Brix and 0-32° Brix. Automatic Temperature Compensating Refractometers provide an ideal solution for situations in which the temperature of certain fluids can affect the refractive index reading of the mix.
