易化されることになる。In such a fluorometer, when a mercury lamp excited by the voltage of an exciter 2 is turned on, the lighting light passes through a filter 4 for selecting a fluorescence wavelength and passes through a sample installation section 8 which is a sample.
A light beam uniformly projected onto the cement above and strongly excited by the fluorescent substance in the cement enters the photomultiplier tube 5. In the photomultiplier tube, the photoelectrons in the incident light beam are multiplied by secondary electron emission on a plurality of photoelectron emission surfaces, and the voltage is amplified by the amplifier 6. Then, the voltage value corresponding to the amount of the fluorescent substance is displayed on the meter 7. By repeating this operation, it is possible to determine the distribution of the amount of fluorescent substance for a plurality of samples (cement), and therefore, the kneading state of the cement. In this case, if the sample H1ilff unit 8 is configured to be able to place a plurality of samples individually and at the same time, and to allow each of these samples to be moved in and out of the optical path, the above work will be facilitated. become.
