PURPOSE:To simplify the correction work of a zero value and a gamma value, by storing data for correcting the zero value and the gamma value in a memory part to correct a measured concn. value. CONSTITUTION:Data for correcting a gamma value and a zero value is stored in a memory part 7 by the correcting data treatment part 6 of a microcomputer. Light from a light source 2 is previous through an object 1 to be measured to be incident to a light receiving element 3. The output thereof is inputted to a central treatment apparatus 4 to calculate a concn. value and correction treatment due to the correction data of the memory part 7 is applied to said concn. value while the corrected value is displayed by a display apparatus 5. Therefore, correction work is simplified. |
