Rontgen Coolant Refractometer
Soluable oil coolant makes an important contribution to extended blade life. It lubricates tooth tips to reduce wear and removes excessive heat from the blade & workpiece. At a recommended oil concentration of 8% - 12% the emulsion will perform both the lubrication and cooling tasks. The oil to water ratio is measured by the RONTGEN refractometer and can be read of a scale visable through the eyepiece.
