PURPOSE:To extract oil in fewer measuring errors, shorter measuring time and greater hygenic safety by serving a sampling container as an oil extracting reservoir, too and adding reagent and solvent directly to the sample. CONSTITUTION:There are provided an oil extracting reservoir 11, a cover 12, a stirrer 16 for reagent and solvent, a filter mechanism 18, an oil concentration measuring part 19 composed of a measuring cell 19a, an infrared light source 19b and light receiver 19c. Either of the cover body 12 and the filter mechanism 18 is supported elastically by an instrument frame, the other is fixed to the instrument frame, they are fitted to the reservoir 11 between them elastically so that they may be free to connect or disconect with the reservoir and the reservoir 11 can be used as a sample reservoir. |
