For determining the concentration of oil in water emulsions and transparent solutions, such as machine shop coolant the Portable Optical Refractometer from Oxford helps maintain the correct mixture in coolant systems is vital to ensure optimum performance from cutting tools. It helps protect the machine and workpiece from corrosion and to reduce the risk of health hazards arising from incorrect concentrations of water soluble oils. I also helps economise the use of water base cutting fluids and grinding fluids.
