The concentration of the active ingredient in a rolling oil emulsion can be rapidly determined, and correction of the concentration of the active ingredient can be undertaken by measuring the measuring the amount of light reflected from the emulsion at the peak absorbing wavelength of the dye to obtain a first reflectance value and measuring the amount of light reflected from said emulsion at a wavelength other than the peak absorbing wavelength of the dye to obtain a second reflectance value for at least two different concentrations of the rolling oil in the rolling oil emulsion, establishing a calibration curve, and then monitoring the rolling oil emulsion in like manner. The results may be utilized to feed additional additive to the emulsion, or may be used to feed water into the emulsion system.
