In this ABBE Refractometer, the liquid solution is sandwiched within thin layers for measuring the refractive index of fluids. Make sure that the samples used in this refractometer are non corrosive so that surface of prisms remains safe and undamaged. While using this refractometer, the refractive index of liquids and gases is lower than glass. Also, this refractometer finds its usefulness in the veterinary field for calibrating plasma protein of blood samples. This refractometer is featured with a digital display for measurement of values. On the other hand, this refractometer eliminates the requirement of discerning between small graduations. The offered ABBE Refractometer has user-friendly interface, portable design and longer functional life.
