An instrument for counting and determining the size of particles suspended in a dispersion medium is calibrated by setting a certified particle contained in the dispersion medium in motion so that the particle repeatedly crosses the sensing zone of the instrument under calibration. An apparatus for accomplishing the calibration method comprises a vessel wherein a dispersion medium and a certified particle are placed and an actuator to set the certified particle in motion whereby a disperse system flow is simulated. Passing a flux of a radiant energy, such as light, through the dispersion medium gives rise to radiation pulses which are used as a basis to set the threshold of sensitivity of the instrument under calibration.
A method for calibrating an optical sensing apparatus which counts particles suspended in a fluid by (i) passing said fluid through a measuring tube having a transparent portion, and (ii) passing a transverse plane of light through said transparent portion of said tube to impinge upon a photodetector, so that particles in said fluid intercept said light and vary the output of the photodetector, said method comprising the steps of:
