A photometric analyzer comprises a measuring block and optical block that includes a photo-detector of luminous flux from medium being analyzed, and source of radiation. A white super-bright light emitting diode with narrow direction of luminous flux, 10-15º, is used as a source of radiation. A digital multimeter is used as a measuring block. A photo-resistor or a photo-diode connected to the digital multimeter in the mode of ohmmeter or in photo-galvanic mode, respectively, is used as a photo-detector. |
