PURPOSE:To obtain information of a colorimetric cell by a remote control by dividing the spectrophotometer to a sample chamber and photometer body, placing the sample chamber in a hot cell and transmitting optical information to the photometer on the outside of the chamber through an optical fiber. CONSTITUTION:The spectrophotometer is divided to the sample chamber 12 and the spectrophotometer body 14 and the chamber 12 is placed in the hot cell. The optical fiber 16 is connected through the wall 10 of the hot cell to the sample chamber 12 and the body 14. The colorimetric cell, sample injecting funnel, waste liquid flow passage and light shielding means are provided to the chamber 12 and are operated by a manipulator. The information of the colorimetric cell is transmitted by the fiber 16 to a detector 20 and a controller 22. Since the optical fiber is sued, the transmission of the information from the colorimetric cell to a remote point is made possible and the spectrophotometer is effectively usable for radioactive material research facilities.
