摘要： PROBLEM TO BE SOLVED: To prevent deterioration of the measurement precision due to adhesion of particles to a prism and glass surface of an optical sensor in an apparatus for measuring the concentration of particles of insoluble components in a lubricating oil. SOLUTION: A lubricating oil of which the concentration of insoluble component particles is to be measured is introduced into a measurement chamber 14 from an oil line of an internal combustion engine through a flow route 2. A sensor 15 is installed in the measurement chamber 14 and the concentration of particles of insoluble components is measured by utilizing light absorption, reflection, transmitting or the like. Since ions produced by ionization by an additive in the lubricating oil adhere to the particles and the particles bear electric charge, the particles are vibrated and prevented from adhering to glass face of the sensor by applying AC voltage or current to the lubricating oil from an AC power source 4.
